Connect with your car's security/remote start system by phone

Viper's SmartStart Bluetooth Module lets you use your smartphone or similar device to secure and start your vehicle, and much much more. Through the Viper SmartStart App that you've downloaded to your device, you can lock and unlock, pop the trunk, and start your car equipped with a compatible Viper system. (Please note: your vehicle must have a remote start system to start your car with this module; otherwise, only security features will function remotely.) If you're within range, you can communicate with your car and control many of its functions from your phone.

Conveniently locks and unlocks your vehicle automatically

The VSK100 will sense the presence of your phone as it gets to within 10 to 15 feet, and will disarm and unlock your vehicle automatically, so you don't even have to take your phone out of your pocket. And when you walk away, your vehicle will lock and rearm itself automatically, the same way. (This feature is not yet available for Android users.)

Other features

The Viper SmartKey system includes a panic button, so you can set off an alarm in case of an emergency. Two auxiliary channels allow you to control additional actions like turning on the interior lights, for example. If your device can use Siri to control Bluetooth functions, you can use voice commands to lock, unlock, and start your vehicle when you're in range. Please note that some features require this Viper SmartKey module to be installed with a compatible Viper remote start or security system in order to operate.

Product Research


Overview: The Viper VSK100 SmartKey Bluetooth module can lock and unlock the doors of your vehicle automatically without pressing a button. SmartKey works with your smartphone (and the free Directed SmartStart app v3.2 or newer), and can be used as a standalone product, or added to an existing Directed Electronics product (Viper, Python, Clifford), including security, remote start, and hybrid systems. SmartKey currently works in the US and Canada. No service plan is required.

Note: The VSK100 works with negative switching locks only. Any other type of door locking system such as positive switching, 5 wire reversal, or single wire door lock systems will require the 607451M (sold separately).

SmartKey Functionality: With SmartKey installed in your vehicle, your doors will automatically unlock when the SmartKey module pairs with your smartphone. Conversely, as you leave the vehicle and get out of Bluetooth range, the doors will automatically lock when your smartphone is no longer paired with the module. You can independently set a range for the locking and unlocking functions. You can also use the two auxiliary channels to perform other functions, such as window roll up/down or pop the trunk. When added to a Viper security or remote start system, the SmartKey module allows you to control your car with your smartphone: lock/arm, unlock/disarm, remote start.

Advanced SmartKey Functions: Other SmartKey functions include:

  • Disable SmartKey: The SmartKey system can be temporarily disabled by sending an active lock or unlock command. When you are again out of range, the passive locking/unlocking is resumed.
  • Shut Off SmartKey: SmartKey can be completely turned off if you wish to disable passive locking/unlocking. You will need to manually re-enable SmartKey when you wish to resume.
  • Sleep Mode: When you are parking the vehicle for an extended period, it is recommended that the Sleep Mode be activated to prevent it from using any battery current. You can "wake up" the module by simply sending a connect request.
  • Power Saver Mode: After 14 hours with no command activity, the SmartKey module enters Power Saver Mode. The SmartKey device remains active so you can connect with it and send commands, but the reduced auto-connect polling lowers the current draw from the battery. Power Saver Mode is automatically exited when you return to the vehicle and a command is sent.

Smartphone Compatibility: The VSK100 SmartKey module works with your smartphone through the free Directed SmartStart App. The app is available from the iTunes App Store. Basic Control is supported on iPhone 3G and newer. The SmartKey passive lock/unlock feature requires Version 3.2 of the SmartStart app, and requires iOS 6 or newer. SmartKey is compatible with iPhone 5s, 5c, 5, 4s, and 4. Version 3.2 of the SmartStart app for Android is not yet available (as of 6/17/14). Windows and Blackberry are not supported at this time.

Operating Range: During normal operations, you should be able to connect with your SmartKey Bluetooth system from up to 200 feet away, however you should set the passive lock/unlock range at approximately 10-15 feet. The range can be affected by local interference, which direction you are from the vehicle (facing it from the side, front, or rear), and whether you are moving or standing still. Your smartphone will indicate the Bluetooth connection status on its display.

Installation: The VSK100 can easily interface with your existing Directed security, remote start or hybrid system. The Bluetooth Control Module is connected between the existing Directed control module and the system's Control Center via the supplied cable. A simple power and ground connection is also needed. If you are installing the VSK100 as a standalone unit, Door Lock, Door Unlock, Start/Stop, and Trunk wires have to be connected in addition to Power and Ground.

Multiple Vehicles: If you have a SmartKey Bluetooth module installed in more than one vehicle, you can choose which vehicle to control right from your compatible smart device. The Cars Screen lets you name and attach a picture for each vehicle you wish to control. You can select the desired vehicle from the Cars Screen.

Not a great Product

Written By Mike_M, Houston, TX on Sunday, September 14, 2014

Crutchfield Customer Review (What's this?)

Not a great product. Seem to work only intermittently. Some times it unlocks the car so slowly that I can unlock it faster. I have another car with a factory system that provides the same function - it is "light years" ahead of this product. The installation and operational instructions are not well written. However when it works it works great. The key phrase is "when it works."

Pros: When it works -- it works great

Cons: Seem to work only intermittently.

Not compatible with Android

Written By claytonjn, Michigan, USA on Monday, June 02, 2014


I purchased this unit when it was first released (still on backorder). At the time it was advertised as being compatible with iPhone and Android. Unfortunately, the Android version of the SmartStart app that adds the SmartKey functionality is still in internal testing and not available to the public. When I contacted Viper about this I was told that the app is being held-up in the review process by Google. I am a Software Engineer and have created multiple Android apps - there is no review process to get an app on the Google Play Store, and certainly not to push an update for an app that has already been published. I was told that the Android update should be coming in a month or two...being familiar with the industry and seeing how long it's been since the last SmartStart for Android update, I would be EXTREMELY surprised if SmartKey functionality EVER makes it into the app.

Luckily, it seems that the advertising has been updated on the Viper website to not specify iPhone/Android compatibility at all (if Viper doesn't state it's compatible and you just assume, it's not their problem) and on the Crutchfield website to state that Android is not yet compatible.

A DEI 8210 harness was required for my installation.

Also, adding adding bluetooth to my existing SmartStart system seems to have made it much LESS reliable when in range of the vehicle. See below.

Pros: Absolutely nothing

Cons: If I am in bluetooth range but it isn't connected over bluetooth, rather than sending commands over the internet as one would expect it seems the SmartStart app still tries to send the commands over bluetooth which obviously fail. Also, bluetooth never connects in the app unless bluetooth was turned off on the device before entering the app, and the app itself turns it on. I am using a Galaxy S5 which has the most current bluetooth hardware available (bluetooth 4.0)

Crutchfield response on Monday, June 16, 2014 We have confirmed that the automatic door unlocking has not yet been incorporated into the Android app. Viper tells us it's very close to release.but not yet. In the meantime, Android users still have to open the app and tap a button to lock or unlock the doors. Or just use your key. But hang in there, the update is coming!

Crutchfield Customer Review (What's this?)

Im not exactly sure why the OEMs haven't adopted this platform yet but its brilliant. We all have key fobs in our pockets (via cell phone) that we recharge the batteries on every night and it only makes sense to use this to activate entry systems on vehicles. I've been waiting for this ever since key fob passive entry became mainstream and this, in comparison, blows it away- I find myself walking up to the car and walking away over and over in amazement at how smooth this system is.

Pros: Simple to use and install.

Cons: I wish you could pair a second phone- but i may just add one more module and pair the 2nd phone to it, This would be a rather expensive fix but it would be worth it.
