Crutchfield Customer Review (What's this?)

Been installing alarms for 13 years and this one works fine. Wiring diagram could use a little more detail on door pin switch types. Programming of features a little fuzzy on the auto-rearming feature. All in all a good alarm.

Pros: Compact with 2 remotes and good price. 2 external outputs. Tech support was good to supply needed wiring for truck up front and called to make sure I had all necessary supplies prior to shipping product. Thanks!

Cons: Instructions, but experience carried me through.

Works nice

Do it your self from Manassas, VA on 11/7/2012

Crutchfield Customer Review (What's this?)

For the price I paid it does what I need. The instructions from the manufacturer could be more detailed. Make sure you have your cars wire diagram. It speeds up the install. The alarm ribbons could be longer.

Pros: Great Price

Cons: Cables could be longer. I had to extend a few of the leads to reach where I needed to hook up.

Very good alarm system!

Crutchfield Customer Review (What's this?)

When I received it I was initially disappointed with the size of the box. I thought that maybe it didn't come with the siren. When I opened it up however, everything was there! The amount of wires you see, is intimidating at first, but after you plug in the shock sensor, valet switch, blue LED, then look at wires which remain, it's not so bad at all. I did call Crutchfield for help in determining a few things for my application and they called me back on a Saturday, late in the day, which is amazing service! I purchased normally closed pin switches (so they are all open when the doors are closed) for all 11 doors I have. All I did was tie them all together to the negative door wire on the alarm brain so when the doors are opened, the switches ground the alarm brain wire which sets off the alarm. Connected the remaining wires to batt, switched batt, ground, siren and I was done. System really works well. It's programmable, small so it can mounted just about anywhere, shock sensor works well. Does everything you need it to do. I will eventually hook it up to the horn circuit so its louder, once I locate the wire on the vehicle. Excellent product at a very good price.

Pros: Small brain, can be mounted or tucked in easily.

Cons: The pamphlet that comes with it has a very good wiring diagram but it could have explained the system a little bit better. Still not sure what the trigger wire does and there are positive and negative wires for the door switch circuit with no explanation for them. The terrific Crutchfield rep helped me out though. It wasn't a big problem at all. Also, the siren by itself isn't extremely loud but does a good job. I suggest hooking up the horns too.

Great Value

Crutchfield Customer Review (What's this?)

When you factor in the price for this alarm system, you can't go wrong. It does exactly what it advertised.

Pros: Low price, two small multifunction remotes, lots of features.

Cons: Was unable to contact the manufacture when I needed a replacement part for one of the remotes.

Great alarm especially for the money.

dlo from Tacoma, WA on 10/1/2012

I purchased this alarm when it was more than double the cost it is now sadly. But it was still worth every penny. For the people complaining about the directions. All you need is the wiring diagram its very self explanatory. I am very happy with this alarm and will be installing it on other cars when the time comes.

Pros: Everything

Cons: Not 2 way transmitter.

it will work

Crutchfield Customer Review (What's this?)

very basic, yet expandable my car did not have power locks yet I was able to wire it up for keyless entry with a few extra parts for about $20 but the wiring was difficult, I was informed that 2 diodes would be necessary for the instalation and they were not required, i was told all I needed to add the power locks was the two actuators, but i also needed two relays (not included). The alarm sets automatically which is kinda a pain but I suspect that can be changed in the units programmable functions.

Pros: Reasonabaly priced, not dificult to wire if you have patience and general wiring knowledge. Support staff available 24/7 to help guide you thru any problems that you have.

Cons: most functions are add ons, lengthy programming to set up additional features

Works as it is supposed to.

Crutchfield Customer Review (What's this?)

4 stars only because of the install instructions, which were a diagram of the alarm and a power lock diagram. LOL on the auto arming have to install the valet need it to PROGRAM the system....then wont auto arm...... Worked as described minus some issues with the vehicle itself.

Pros: Works! Keyless!!

Cons: Little Sensitive. BAD install instructions.

Great Alarm System

ReggieD from Hoschton, GA. on 6/4/2012

2010 Ford Mustang
Crutchfield Customer Review (What's this?)

This is a very simple to install alarm system. I used the same alarm years ago on my kids' cars while they were in high school (97 mustang and 96 Honda Accord) . Since then, after college, they purchased newer cars. 2010 Mustang and 2004 Mini Cooper S. Installation was very easy with the help of Crutchfield's tech support. I noticed other comments below saying the alarm sets itself. I believe this is user error. The alarm comes factory set in passive mode. Meaning the alarm sets itself on after about 30sec automatically. You need to go into the program mode and turn this feature OFF.

Pros: Simple to install, Great features, small size, great support for from Crutchfield,

Cons: The port that controls the exterior light, trigger the park lights with a 12v signal. The 2004 Mini Cooper lights are controlled with a ground signal. Because the signals are opposite I will need to add a relay. The alarm should have the ability to have you set the light controls to +12v or ground by using maybe a jumper. Make wires longer.

Good, but.....

Bob from Overland Park, KS on 5/4/2012

1988 BMW 325I
Crutchfield Customer Review (What's this?)

This seems to be a good alarm for the money. I noticed another entry form a convertible owner that I would agree with -- I don't like the alarm setting itself. The only way to circumvent this is to disengage the the pins on the doors and trunk. Wish I would have known this before I got it..because I would have got a different one for sure. I also disabled the shock or disturbance device since it was either to sensitive or not sensitive enough depending on what you were doing. The Valet button was pretty cheep and I didn't install that either. For the money I'm pleased with auto door and trunk locks and the general assurance of security.

Pros: It makes me feel alittle safer. Good price..

Cons: The alarm sets itself. Pretty distracting when your working on the car or sending it to a repair shop.

My Review

Randall from Aurora,Co on 3/30/2012

2005 Jeep Wrangler
Crutchfield Customer Review (What's this?)

Good alarm for the price only thing I don't like about the alarm is it sets its if your working on your car,washing it or whatever it will go off on you. Wish I would have knowin this before I got it..because I would have got a different one for sure. Its not as sensitive as I thought..I have a soft top and I could take off my side windows without the alarm going off. I jumped on the back of my bumper and the alarm didnt go off. If you touch the dash or steering wheel the alarm goes off.

Pros: It makes me feel alittle safer..I guess better then no alarm. Good price..

Cons: The alarm sets it will go off on you if your washing your car or if someone is working on it or you are. Its not as sensitive as I thought it would be.

Great unit

Doc Bear from Diberville, MS on 3/3/2012

Crutchfield Customer Review (What's this?)

Unit was straight forward to install. Had to call customer service once to confirm which wire to connect to but not a big problem. I installed it in a 2007 Toyota Tacoma. Works great so far? Install time was about 5 hours, but I wanted to make all the wires look neat.

Had the alarm installed in about an hour the hardest part was removing the few trim parts other then that I installed it on my Nissan in no time

Pros: Super easy install

Cons: Nothing

Good, compact, but adding features adds cost

MikeyK from Pasadena on 9/1/2011

Crutchfield Customer Review (What's this?)

This is a nice, compact system that can be tucked away in small spaces. But because it's a basic unit, if you want to enable some features, it means buying relays. The installer said that the higher end systems have relays built in. For my wife's 99 RAV4, we needed 5 relays for our install, and that didn't even include the Dome light feature which we didn't enable. We needed 1 for the car horn (didn't want to install a siren), 1 for the parking lights, 1 to lock the car, and 2 to unlock, as we decided to use button 2 to unlock all doors, main button to unlock driver only. Again, a more expensive unit would have that feature built in. Ultimately we spent $75 on relays. But I like the features of the alarm, and it works as advertised.



Great Product

This is an excellant alarm for the money. Many great features and expandable. Hook up was easy and the extra info that was sent by the Crutchfield team was great as well.



Great Basic Alarm

John from Cleburne, TX on 6/13/2010

Crutchfield Customer Review (What's this?)

This is a good basic alarm. The installation instructions are lacking but Crutchfield was there every step of the way and I was able to install it without too much difficulty. Unless you are a professional installer, buying from anywhere else would be a mistake. Thanks again Crutchfield.



Great budget alarm

Anonymous from NC on 5/25/2009

Crutchfield Customer Review (What's this?)

The only reasons I did not give this 5 stars is the lack of a progressive unlock feature, and the included shock sensor did not work properly. I simply used channel 3 for the unlock of the 3 passenger doors which works fine for me. I installed this in a 1998 Cavalier which I had previously installed aftermarket lock/trunk actuators in. Install was no problem for me, however I am a Vehicle Repair Technician and work with vehicle electrical/electronic systems on a daily basis so my knowledge is above average. Existing power locks and electric trunk release will be an easier install than having to add everything like I did. I discovered my car had 2 separate dome light switch circuits and had to diode isolate them from one another when connecting to the alarm, I found a diagram online and bought the diodes from Crutchfield. I used the existing trunk light switch to tie the trunk into the alarm as well. I purchased the better "air pressure" shock sensor from Crutchfield and it is working great , much better unit than the one included withe the alarm which never worked right. The range on the remotes of this system is the best of any alarm/keyless I have owned. Much better than the Viper in my truck. Siren is compact and LOUD! I hid it behind the front park light so it would be hard to cut the wire!

Complicated for an old geezer

John from Gainesville, GA on 2/9/2008

Crutchfield Customer Review (What's this?)

Crutchfield's installation instructions were excellent but the installation would still have been beyond me. Fortunately my son stepped in and between us and six hours of hard work we got the installation done in first class fashion. The Crime Guard works flawlessly and I am very pleased with it and with Crutchfield's excellent service.




Hands-on research

Product Research


Door Lock Outputs: The Crime Guard 350i5 car alarm requires no additional relays for negative trigger vehicle door locking systems. Two relays (such as 120E5000) are required for positive trigger and 5-wire reversal (rest at ground) systems.

Programmable Door Lock Pulse: The alarm brain contains a jumper that allows you to set the duration of the lock/unlock pulse. With the jumper on (default), the lock/unlock pulse is 0.8 seconds. With the jumper removed, the length of the pulse is 4 seconds.

LED Status Indicator: The alarm comes with a bright blue LED to indicate the status of the alarm system, and which zones may have been violated. After the vehicle's ignition is turned on, the LED will indicate the number of transmitters that are programmed to operate the alarm (Automatic Transmitter Verification). The LED should be placed in plain view to indicate the presence of an alarm system to potential thieves, as well as provide status indications to the user from outside the vehicle.

Valet Switch: The Valet Switch is a small black push-button (0.58" diameter, 0.454" height) with three main functions:

  • Valet Mode: turns off the security operation of the system, including the Last Door Arming feature (if used).
  • Emergency Override: used in conjunction with the vehicle's ignition key, to disarm the security system, in the event the transmitter is lost or becomes inoperable.
  • Programming: used in procedures for programming operational features and for programming transmitters to operate the system.

Starter Disable Relay: The 350i5 includes a starter disable relay. When the starter kill feature is activated, you will not be able to start the vehicle once the alarm has been armed. When the alarm is disarmed, the starter disable will be deactivated so you can start the vehicle.

AU-77MP Multi-tone "Psyren": The included "psycho siren" emits two tones simultaneously, making it sound like two different sirens going off at the same time. The compact size of the siren allows placement flexibility. Dimensions: W=3.39", H=2.98", D=2.774"

AU-84TM Shock Sensor: The 350i5 comes with a piezo-element Dual Zone Shock Sensor with adjustable sensitivity. The initial zone is a pre-warn stage which, when triggered by a light bump, will cause the alarm to emit a series of chirps. The second zone which is triggered by a more severe impact will cause the alarm to emit a full siren alert. Dimensions: W=1.508" (2.137" w/tabs), H=1.028", D=2.016"

Anti-Carjacking Protection: The 350i5 is equipped with three separate Anti-Carjacking protection features, whose operation may be selectively activated by the ignition, by an open door (while the engine is running), or by the transmitter. All three are programmable and must be turned on to operate. Once activated, a sequence begins that, if not manually canceled, will eventually end in the full alarm sounding:

Elapsed Time After Activation Alarm Reaction
0-20 seconds No signs
21-30 seconds LED blinks slowly
31-45 seconds LED blinks rapidly; siren/horn chirps once every 2 seconds
46-60 seconds LED blinks rapidly; siren/horn chirps once per second
At 61 seconds Alarm triggers with siren/horn and flashing lights

Transmitter Protection: One of the most vulnerable area of a remotely controlled system is the transmitter (remote). The system has three security safeguards for the transmitters:

  • Code Jumping: The system's Code Jumping feature randomly changes the code each time the transmitter sends a signal, rendering "code grabbing" devices useless.
  • Automatic Transmitter Verification (ATV): The system's Automatic Transmitter Verification shows the total number of transmitters which can operate the system by flashing the Status Light with this number for 90 seconds every time the ignition key is turned on.
  • Unauthorized Transmitter Alert: This system warns you whenever a new transmitter has been coded to operate alarm. For the first 48 hours after the programming mode has been accessed or the main power has been disconnected, the siren will emit a series of chirps each time the car is started and the ATV visual display increases to 90 seconds. If the Automatic Transmitter Verification indicates more than the usual number of transmitters are coded, you know that someone (a mechanic, valet, etc.) has managed to code an additional transmitter to the system, and you should recode your transmitters to prevent a potential thief from disarming the system. The alarm is capable of learning the codes for up to four remotes.

Remotes: Two 4-button remotes are included with the system. The remotes include random code encryption, which renders code grabbing devices useless by changing each signal sent by the remotes. Each remote has a range of up to approximately 1000 feet. The remotes have the following functions:

  • "Lock" button:
    • arms system and locks doors (if connected)
    • press and hold for 3 seconds to activate the panic mode (siren sounds/parking lights flash)
  • "Unlock" button:
    • disarms system and unlocks doors (if connected)
  • ( · · ) button:
    • pressing twice within 3 seconds will silent arm alarm
    • pressing twice within 3 seconds will silent disarm alarm
    • press and hold for 3 seconds to activate the auxiliary channel output (typically used to for trunk release operation)
  • ( · · · ) button:  
    • press and hold for 3 seconds to activate the 3rd channel remote output (typically used to trigger a remote car starter or window roll-up module)
    • with ignition on, press and hold for 3 seconds to activate remote anti-carjack feature
  • 2-Button Combinations:
    • Lock + ( · · ): Shock Sensor and Prewarn Bypass

Dome Light Turn-on: The alarm has an output that is dedicated to dome light supervision operation. A relay will be needed to control a negative or positive trigger dome light. When the alarm is disarmed, the dome light supervision feature turns on the dome light for 30 seconds, or until the ignition is turned on. The dome light supervision feature helps you locate your vehicle at night, and it allows you to see an intruder hiding inside the vehicle before you open the door. If you desire, you can configure the alarm to operate a different accessory such as a window roll-up module with this output.

Safety Disarm Feature: When the alarm is triggered and in a full warning condition, the safety disarm feature allows you to disarm the alarm without unlocking the doors of the vehicle. This feature allows the vehicle to remain secure, even though an activated system has been disarmed. The Safety Disarm Feature is particularly useful when the vehicle is exposed to conditions, such as storms, trains or animals, which may cause false triggers.

Remote Outputs: The 350i5 has two remote outputs (2nd and 3rd channels). The 2nd channel output is typically used to operate your vehicle's power trunk release. You can also use it to operate a remote car starter or window roll-up module. The 3rd channel can also be used to trigger a remote starter or window roll-up module. It can be configured to provide a momentary output or a longer output, depending upon the connected accessory.

Alarm Condition Recall Memory: If the system enters an alarm condition, the LED will begin to flash in sequence to indicate which zone caused the trigger; the recall memory circuit can store two consecutive zone violations (if there has been more than two zones violated, the memory will recall the two most recent violations). The LED will flash twice then pause for a hood or trunk violation, three times then pause for a door violation and four times then pause for a sensor violation.

Programmable Features: The following programmable features are easily programmed using only the ignition, valet button, and a transmitter:

  • Auto Rearm: Allows the alarm to rearm itself if it is disarmed and a vehicle door is not opened
  • Last Door Arming: Configures the alarm to automatically arm itself 30 seconds after the last door is closed with the ignition "Off". Auto Rearm allows the alarm to rearm if a vehicle door is not opened after the alarm is disarmed.
  • Doors Lock with Last Door Arming: Adds the automatic door locking of the vehicle's doors to the previous feature.
  • Double Pulse Unlock: Sets alarm to give 2 unlock pulses upon disarm for cars that require it.
  • Immobilizer Mode: If this mode is programmed "On", the starter interrupt will remain engaged after the alarm is disarmed until the vehicle's ignition is turned On and you press and release the Valet button. Upon disarming the Immobilizer mode, ignition activated anti-carjacking will be automatically canceled (of programmed on).
  • Siren/Horn: This feature configures the alarm's Brown/White horn-honk output wire. The wire can be configured to honk the horn in addition to the Brown wire operating the siren, or take over all of the siren's functions so that no siren is necessary.
  • Shock Sensor False Alarm Bypass: This feature will temporarily turn off the shock sensor and pre-warn zone if the pre-warn is triggered 10 times or the instant trigger zone is triggered 5 times while the alarm is armed. The bypassed zones will be reinstated with next alarm arming.
  • Dome Light Delay Bypass: This feature will turn off the three chirp open zone warning when arming the alarm with the remote control. This is for use in vehicles that keep the dome light illuminated after the doors have been closed.
  • Ignition Activated Anti-Carjacking: This feature turns the alarm's Ignition Anti-Carjacking feature on or off.
  • Remote and Door Activated Anti-Carjacking: This feature turns both the alarm's Remote Control and Open Door activated Anti-Carjacking features on or off.
  • Dome Light or Window Roll-up: Configures the alarm's black/white wire to operate the dome light or window roll-up module or other accessory.
  • 3rd Channel Output: Configures the alarm's pink wire to operate an accessory or window roll-up module.
