You can start your car from up to 1500 feet away — that's over a quarter mile — with Viper's Model 4105V remote start system. Just push a button on the keychain remote, and your car will be warmed or cooled just to your liking when you get to it. The remote also unlocks and locks your car, and even allows you to arm and disarm a factory security system in most cars. An auxiliary channel allows you to add a function like popping open the trunk or lowering the windows. The Model 4105V system is also compatible with any Viper SmartStart module, which allows you to start your car via your smartphone with no limit to the range.

Important Note:
We offer a databus interface module that can save you lots of time when you install a Viper remote start system in most vehicles. Chat or call us at 1-888-955-6000 to see if the interface will work with your vehicle.

If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this remote start system yourself. If not, please consider having your system professionally installed by purchasing an InstallCard.

To ensure vehicle compatibility, please enter your vehicle information in OutfitMyCar. Your order will be reviewed by our Car Experts group, who will contact you if further information or recommended accessories are needed.

Great Tech Support

Crutchfield Customer Review (What's this?)

Product worked as advertised. Tech support was very helpful - called/emailed them several times with questions. They were helpful and patient every time. Documentation provides the minimum information required to get it installed correctly. That statement is not a knock on the product, just a warning that experience with this kind of installation is pretty much a prerequisite.

Pros: Works as advertised. Very good range.

Pros: It starts the car as promised.

Cons: Car shuts off as soon as you get near with auto unlock?

Excellent addition to my already awesome features. However I now warm my vehicle from the the warmth and comfort of my home.

Pros: Easy to use

Crutchfield Customer Review (What's this?)

I installed this in my 2011 Ram 2500, installation wasn't straight-forward in the paperwork, but two calls to Crutchfield support got me fixed up. Professional installation would be good for someone who doesn't know electricity, working with a meter and basic electrical testing knowledge. Get the T harness and datalink module to make installation easier.

Pros: Good quality unit. Fool-proof connectors. Works as described. Crutchfield team always helpful and easy to work with.

Cons: Installation is not easy.

The Crutchfield team is great

Crutchfield Customer Review (What's this?)

I gave this a 4 rating because of the lack of installation instructions. The Crutchfield support team though helped my with all the answers I needed. If I purchased this from any other company I probably would have returned this. I also purchased the Dball to go with it. Works great. I would never buy any automotive electronics from anyone but Crutchfield.

Pros: The Crutchfield support team Both products like they are advertised.

Cons: Lack of installation manuals

Crutchfield Customer Review (What's this?)

If you're looking for a basic remote start system, this is an excellent choice. It has a good range and is easy to use. The installation instructions from Viper are very basic, but Crutchfield will send you the wiring data for your specific vehicle. With that and a DVM, installation is easy. You need a good digital voltmeter; don't use an analog or you risk damaging your vehicle.

Pros: Good performance, easy to fit under the dash, easy installation.

Cons: Factory instructions are basic; you'll need Crutchfield's wiring diagram or one from the factory service manual.

product works great. It's a keyless entry system with remote start not

Crutchfield Customer Review (What's this?)

It works as its supposed to. Just be clear that this is not an alarm and doesn't even have a blinking light bulb. Its a keyless entry system with remote start. It doesn't sound when you open the door. My mistake for not knowing that. Most cars now have an alarm on them already. This would be perfect for you.

Pros: Brand recognition and it works.

Cons: You need a profesional to install. I paid $175 to a guy close by. Should of got an integrated alarm.

Works Well

Review on Viper 4105V

Written by: Serge from Tularosa, NM on February 21, 2014

Crutchfield Customer Review (What's this?)

I'm very pleased with my new alarm start system. It works very well to keep my car audio equipment safe from vandals.

Pros: It's a lot easier to start my car specially if I'm in a hurry to go out and run errands or if I'm running late for classes at my university.

Cons: On certain days my alarm gets stuck and won't go back to normal settings,so I have to take it in to get checked out.

Great Remote Starter

1998 Chevrolet K Series
Crutchfield Customer Review (What's this?)

Great remote starter. I purchased the Viper 4105 V remote starter to replace a unit I had installed years ago in my fathers truck that the remotes quit working on.

Pros: Cruthfield's customer service and tech support is by far worth every penny to purchase the product from them instead of anyone else. I was able to contact them on a Sunday for technical help and we were able to work through my issues without any problem. The called me back to follow up to see if I had any other questions.

Cons: Instructions are a bit vague on where to connect some of the wires. But I believe that to be the case with any remote starter or alarm system. DIY installers need to have a good knowledge of automotive electronics on how things work in order to install, including a wiring schematic of your vehicle. Crutchfield did offer a schematic for my vehicle.

Remote Starter Features
Keyless Entry Features

Remote Starter Features

Overview: The Viper Model 4105V Remote Start and Keyless Entry system can start your car and run it by remote control from a distance of up to 1500 feet for a preset amount of time. It also functions as a keyless entry system, remotely locking and unlocking your vehicle's power door locks. The Model 4105V does not provide car security.

Note: The remote start function is for fuel injected, diesel, or hybrid vehicles only.

Remote Starting: Pressing the (*) button on the remote for a second will remotely start the vehicle and run it for 12 minutes. You can extend the run time to 24 or 60 minutes. If you wish to pre-heat or pre-cool the vehicle, you must preset the climate controls prior to starting the vehicle. When you are ready to drive the remotely-started vehicle, insert the ignition key, turn it to the On position (not Start), and press the brake pedal.

Crank Time: If the unit is programmed for no engine checking or voltage sense, the crank time must be set to the appropriate duration. The default setting is 0.6 seconds. It can be lengthened to 0.8, 1.0, 1.2, 1.4, 1.6, 1.8, 2.0, or 4.0 seconds.

Diesel "Wait To Start" Timer: If you have a diesel vehicle, you can set the starter to delay by a few seconds before engaging. The "wait-to-start" duration can be set to 15, 30, or 45 seconds. Gasoline engines will start approximately 4 seconds after the system acknowledges the start command by flashing the parking lights.

Valet Takeover: This feature allows the vehicle to remain running after the key has been removed from the ignition. This is useful for those occasions when you wish to exit and lock the vehicle for short periods of time while leaving the motor running and the climate controls on.

Automatic Shut-down/Starter Lockout: After the vehicle is remote-started, the remote starter will shut down when the brake pedal is pressed, the hood is opened, if the run time expires, or when the remote start command is sent again from a remote control. In addition, if the hood is opened or if the brake pedal is pressed, you cannot start the vehicle using the remote starter.

Timer Mode: The Model 4105V can be programmed to start and run the engine every three hours, for a maximum of six cycles. The engine will run for the programmed run time (3, 6, 9, or 12 minutes) and then shut down. After three hours, the system will restart the engine. The Timer Mode works only when the system has been locked with the remote.

Anti-grind Circuitry: Whenever the vehicle is started using the remote, advanced anti-grind circuitry prevents the starter from being engaged using the key. (In other words, it won't let you try to start the car with the key if the remote starter has already been engaged.) This prevents damage to the starter motor. The optional Failsafe Starter Kill relay must be installed in order for the anti-grind circuitry to work.

Shutdown Switch: You can temporarily disable the remote start unit to prevent the vehicle from being remote started accidentally by switching the supplied neutral safety toggle switch to the Off position.

Keyless Entry Features

Locking/Unlocking The Vehicle: Each 7145V remote control has separate "Lock" and "Unlock" buttons. When the "Lock" button is pressed, the doors lock, the horn in the vehicle honks once and the parking lights flash once. In addition, the Failsafe Starter Kill feature is activated, preventing the vehicle's starter from cranking. When the "Unlock" button is pressed, the doors unlock, the horn honks twice, and the parking lights flash. In the Silent mode, the doors lock/unlock without the horn honks, and the parking lights flash to confirm the operation.

Note: When interfacing with any other type of factory door lock system besides negative switching locks, or when adding aftermarket actuators, two relays (such as two 120E5000s) or a door lock module (607451M) will be required. If your vehicle requires the use of a Data Integration module that controls your factory door locks, no extra parts besides the Data Integration module will be required.

Trunk Release: When connected, the accessory output can operate a factory power release for the vehicle's trunk or hatch. An optional relay may be needed, and if the factory release is not power-activated, a trunk release solenoid can often be added (Directed part # 522T).

Car Finder: If you're having difficulty finding your vehicle in a crowded parking lot, the car finder function will cause the lights to flash 5 times slowly, allowing you to locate your vehicle.

Panic Mode: If you are threatened in or near your vehicle, you can attract attention by triggering the system with your remote. Panic mode requires the horn honk circuit to be connected.

Customer Q&A

Crutchfield asked  
Why did you buy this?

Your website showed it as a top seller, and in fact the installer I called first recommended it as well. I only needed basic remote car starting, and wanted to maintain my existing keyless entry with arm/disarm of the factory alarm. An inexpensive way to have goodies added to my car, like starting the car from in the house when it's below freezing outside! Yay, I really can't wait. [ Julia  Jan 17, 2016 ]

9 questions already asked

I had my Viper professionally installed and just recently I had issues with my F150 not starting. When I contacted the installer I was told that the way this remote start system works it should in no way affect "regular" starting i.e. with the key. My issue ended up being the fuel pump and in regard to the check engine light, that little gem can represent so many things I'd take it to your trusty mechanic, have them pull a code, and solve the issue at the source. BTW I love my Viper, it has gone from "nice to have" to "have to have." [ Matt  Jan 28, 2016 ]

IT comes with next to nothing. It does tell you what each wire is for but they don't give you step by step or even how to wire in the switches they leave it to your imagination. On the plus side Crutchfield was nice enough to send a chart of what wire colors = what on my car. [ Dan  Dec 04, 2014 ]
yes, the unit comes with instructions and we send you an email with details about the wiring in your vehicle. [ RICHARD  Dec 04, 2014 ]
not that I am aware of. [ JAMES M  Dec 04, 2014 ]
I had to hire a stereo institution company. [ JERRY W  Dec 04, 2014 ]
As much as I wish it had pinpoint the installation process telling me which wires go where and which ones to use, it doesn't. You have to have the knowledge of how to use a voltmeter and find which wire you're looking for on your vehicle. I personally relied on the tech support to help me and they went step by step and had even emailed me a sheet of which wires to use and where they tie into. Even if I wasn't able to locate the location of some wires, they emailed me pictures. [ AUSTIN J  Dec 04, 2014 ]
I bought this last December. It came with very good instructions but not step by step instructions. I had to have a guy install it who worked for a custom audio shop. Well worth it though. Great product at a terrific price! [ James A.  Dec 04, 2014 ]
This product will work with a diesel, but will not work with a manual transmission. You would need to step up to the 6074606V to get manual transmission compatibility. [ Jeff  Nov 25, 2014 ]  Staff
You can make it work but is not very safe due to the fact that someone might forget to leave the transmission in neutral. [ JAY  Nov 22, 2014 ]
I do not know [ GEORGE  Nov 22, 2014 ]
Don't quote me on this but I believe it will. Contact Crutchfield's customer service. They are extremely knowledgeable and helpful. [ SHANE W  Nov 22, 2014 ]
You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility. They will be able to pull up your vehicle and see if this will work. If it does not, then they will also be able to discuss other options with you. [ Krissy  Jan 15, 2014 ]  Staff
