Our take on the Code Alarm CA1053

by Buck Pomerantz
Code Alarm

We offer vehicle-specific interfaces that you'll need to complete your car security installation. Please identify your vehicle as we review every order to make sure you've got everything you need.

Secure your vehicle

Your car may have a keyless entry remote, but that doesn't mean you've got a security system built in as well. And even if you have a factory-installed security system, very few of them include a siren and an impact sensor, for instance — essential features if you want to stop a thief from smashing a window and taking what they want.


Code Alarm's CA1053 keyless entry and security system protects your car and its contents with an impact sensor and more, and gives you the convenience of remote door locking. The dual-stage shock sensor system's siren chirps a warning with the first impact, then goes off full blast if the intrusion continues. The system includes:

  • a dual-stage magnetic shock sensor that detects unauthorized tampering;
  • a powerful 125 dB weatherproof siren;
  • two 4-button remote controls;
  • remote door lock and unlock;
  • a starter interrupt feature which shuts down ignition during unauthorized use.
  • DBI port for direct interface connection

More features

Carjacking protection and automatic rearming provide additional safety features. The CA1053 also has an override switch for valet parking, while the "silent choice" feature allows you to arm and disarm your car alarm without disturbing your neighbors. The car-finding feature will sound your alarm at low volume so you can find your car quickly in a crowded parking lot.

Alarm Features

Alarm Features

Overview: The Code-Alarm CA1053 Vehicle Security and Keyless Entry System, a part of the Professional Series line, will protect your vehicle and its contents, and can remotely lock or unlock your doors. It comes with two remotes.

Remotes: The CA1053 comes with two 1-way, 4-button remote transmitters (CATX4). The remotes operate at 433 MHz with additional SAW filtering to give you excellent range with less RF interference. The remotes have four buttons for lock, unlock, vehicle locator/panic mode, and trunk release. Each requires one CR2016 battery (installed). Additional remotes (up to a total of 4) can be programmed to operate the alarm.

Data Bus Interface (DBI) Port: The alarm's control module has a 4-pin Data Bus Interface (DBI) port, which allows you to plug in an optional FlashLogic Transponder/Door Lock/Remote Start Interface (220FLCAN) directly into the system. These modules, compatible with many late model vehicles, can save considerable installation time by eliminating the need to find and splice various wires within the vehicle. Typical connections that are made with the interfaces include tachometer, brake, door locks, and ignition/starter.

Note: Even with the interface, there will be some required splicing into your vehicle's factory wiring.

125dB Siren: The CA1053 includes a siren which emits a single tone pattern at 125dB, which is equal to the threshold of pain in humans. Its compact size (2-3/4" footprint diameter, 3-3/8" horn diameter) gives you additional mounting flexibility. The weatherproof design keeps the siren operating flawlessly in the harsh, under hood environment.

Silent Choice: The Silent Choice feature allows you to control the arm/disarm chirps from the remote control. When Silent Choice is activated, a second press of the "lock" button is required to activate an audible arming response from the vehicle. The system default is Silent Choice disabled, which means the alarm will chirp for arm and disarm on the first button press.

Active/Passive Operation: The system can be programmed for passive or active arming and door locking. Active arming/locking requires the use of the remote to arm the system or to lock the doors. When programmed for passive operation, the doors lock and the system is armed automatically 1 minute after the last door is closed.

Hidden Alarm: You can set the alarm to activate the Hidden Alarm function. The security system will arm with the Hidden Alarm function in which the siren and/or horn will be silenced if the system is triggered.

Door Locks/Trunk Release: The alarm can lock and unlock the vehicle's doors using the remotes. The alarm works with negative switching locks. All other locking systems will need a Code Alarm Door Lock Relay Kit, or two relays (120E5000), unless you are using a data interface with door lock control. In addition to unlocking and locking the doors, the system can also open the vehicle's trunk or hatch.

Two-stage Door Unlock: The alarm's door lock function can be set to operate in two stages. The driver's door only is unlocked with one press of the unlock button. A second press of the button within 3 seconds will unlock the remaining doors.

Built-in Shock Sensor: The built-in dual-stage magnetic shock sensor will respond with a warning chirp when there is a light impact to the vehicle. Harder impacts will fully trigger the alarm. You can bypass the shock sensor for one arm cycle, and will default back to normal operation the next time the system is armed.

Starter Interrupt Output: When the alarm is triggered, the system will disable the vehicle by interrupting the circuit to the starter via a relay. As long as the system is in alarm mode, the vehicle's engine cannot be started, preventing a possible theft. The relay needed to install this feature is included with the alarm.

Personal Protection Alarm Mode: The alarm's Personal Protection or Panic Mode will activate an alert when you press and hold the panic button continually for three seconds. The transmitter's normal functions are suspended during panic mode, except to allow you to lock or unlock the doors. You can manually shut off the alarm with the transmitter, or the system will automatically stop after 30 seconds.

Progressive Car Finder: To assist you in locating your vehicle in a crowded parking lot, the Progressive Car Finder feature will sound the alarm and/or honk the horn five times at low volume. If you have not located the vehicle, the system will repeat the action at increasingly higher volumes (low, medium, high) with each press of the button.

Carjack Mode: The CA1053 features a Carjack mode, which must be turned on in system programming. The Carjack mode provides a delayed and progressive alarm response, starting with siren chirping, to full alarm with flashing parking lights, to starter kill activation, rendering the vehicle disabled.


FlashLogic Interface Module: The optional FlashLogic Databus Interface Module (220FLCAN) communicates with your vehicle's Databus to provide plug-in capability for various functions of the Code-Alarm security system. Typical functions include tach input, door trigger, dome light supervision, factory alarm arm/disarm, trunk/hatch open, diesel glow plug input, remote start, and factory keyless entry controls. Compatibility and available functions vary depending upon year, make, and model of vehicle.

Note: Before installing, the FlashLogic module will need to be configured for your specific vehicle via web-update. Some splicing into factory wiring will be required.

Universal Transponder Interface (UTI): The optional Universal Transponder Interface (UTI) works with vehicles that use an "immobilizer" key system, allowing you to operate the alarm system without interfering with the vehicle's anti-theft features. The UTI works with vehicles that have a transponder or RF-based immobilizer, including the GM Passkey systems.

Digital Tilt Sensor: The optional Code-Alarm DUB1 digital tilt sensor can detect when the angle of your vehicle changes and trigger the alarm to protect you from tow trucks and tire or wheel thieves. After you have parked your vehicle, the DUB1 has a digital self-leveling feature to determine the angle of your parked vehicle. If that angle changes due to the vehicle being jacked up or towed, it will trigger a full alarm in the security system.

Door Lock Actuators: Power door locks can be added to a vehicle with manual door locks with a Door Lock Actuator, enabling you to lock/unlock your doors with the CA1053's keyless entry feature. A Standard 2-wire Door Lock Actuator (220DA1) is available for normal manual door locks. For cable-driven door locking systems, a Motor Clutch-type Door Lock Actuator (220DA2) and a Cable Kit (220CLBK) will be needed. You will need an actuator for each door you want to control.

1-way Remote Transmitter: Up to 4 remote transmitters can be used with the CA1053 security system. Additional CATX4 1-way 4-button remotes can be purchased and programmed to operate your system.

Good basic alarm - if that's all you need

Written By Raymond M., Oregon on Sunday, July 20, 2014
Crutchfield Customer Review (What's this?)
I don't have a fancy vehicle (15 year old 4Runner) so I don't need a fancy alarm. My factory installed alarm's remote broke and I had no way of replacing it so had to get a new alarm. Crutchfield sends an electrical diagram sheet for my truck which helped a lot. I had the advantage of copying the previous wiring so if you are installing this new for the first time, it'll take you a little longer, and you may need a voltmeter so if you can't do that, then take the alarm to an installer.
Good selection of basic features.

quality keyless entry at affordable price

Written By Anonymous, greenville, nc on Sunday, May 25, 2014
Crutchfield Customer Review (What's this?)
Excellent range, simple installation, overall great entry level keyless entry and security kit. I have installed this kit on both my 98 Cherokee and 98 Grand Cherokee due to this costing less then one new OEM remote, and it gets MUCH better range.

Car Alarm

Written By Mike, Jax, FL on Wednesday, February 05, 2014
Crutchfield Customer Review (What's this?)
Installed the car alarm over a two day period and it works great. It is challenging to find all of the wires you need to tap into but the wire color guide was a big help. Phoned Tech Support a couple of times when I got in the weeds and they put me back on track. I don't think I would try installing one without some good Tech Support to back me up. It's too complex unless you have experience.
Works great. Opens the door locks, arms, disarms, makes loud noise long time when tripped.

Could you tell me how to use the Silent choice option? Like which button sequence to use etc. [ Devin  Jun 13, 2014 ]
1 answer
  • I do not know the answer to this question. I had a related query for Crutchfield and I was referred to the Manufactured of the alarm: Audiovox Electronics Corp. customer service. [ LEONARD   Jun 14, 2014 ]
I would be installing this in an 02 Jeep Wrangler. I would only be using the start kill and shock sensor as my Jeep doesn't have power anything and I normally roll with the doors off anyway. Sense I'm only using those basic features, can I get by with out the interface module? Is there something else this module could help with in this instance that I'm missing? [ James  Mar 10, 2014 ]
3 answers
  • Don't know about this situation. [ GEORGE   Mar 17, 2014 ]
  • Are you talking about the interface module that is the alarm system? If so then yes you need it as it has the shock sensor built in and controls the arming and disarming of the sensor and start kill. If your talking about the dbi controlled interface that attaches to the alarm, then no as it only benefits you if you have a lot of power features. Hope this helps. [ Victor   Mar 10, 2014 ]
  • I understand the interface module was to run door locks, we put this on a 90 Miata that did not have power anything too, we added lock actuators and used the interface module. Works really well [ THOMAS   Mar 10, 2014 ]
can this system work outside the US? [ valerie  Jan 16, 2014 ]
1 answer
  • For details on installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to discuss use in vehicles outside the US. [ Jeff Staff  Jan 16, 2014 ]
