Our take on the Viper Model 4105V

by Buck Pomerantz

We offer vehicle-specific interfaces and harnesses that you may need to complete your remote start installation. Please identify your vehicle as we review every order to make sure you've got everything you need.

Start your engine remotely

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. Two auxiliary channels allow you to add functions 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.

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, one of the accessory outputs 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.

Review on Viper 4105V

Written By Serge, Tularosa, NM on Friday, 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.
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.
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

Written By Mark G., Denver CO on Tuesday, February 04, 2014
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.
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.
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.
