Start, locate and control your car from virtually anywhere with your iPhone, or Apple Watch!

“Making the cloud-connected car a reality”

"The coolest thing at the Consumer Electronics Show"

"Without a doubt, one of the coolest apps I've ever seen"

The Viper brand created the connected car category for the automotive aftermarket with the launch of Viper SmartStart in 2009. With the release of its all-new 4th generation Viper SmartStart app, connecting with and controlling your vehicle is easier than ever – including control via your Apple Watch.

- Add a Viper SmartStart module to the Viper system in your car so you can start, lock and unlock your car from virtually anywhere. Receive push or text notification if your car alarm goes off.
- Add a Viper SmartStart GPS module instead, and you can also locate your car, share activity on Facebook (because your car needs friends, too), and set safety notifications if your car is speeding or goes where it's not supposed to go.
- For the ultimate connected car experience, install a complete Viper SmartStart Digital System and you’ll also get notified if your vehicle sets a diagnostic code, along with direct feedback from the car databus for feature status. Check out the 60 Day Free Trial GPS Premium service that’s included at no extra cost with these systems!

Are you tired of carrying around another clunky remote control on your keychain, or finding yourself out of range when you really need to warm up or cool down your car before getting in? Now you can securely remote start, lock/unlock, or find your car just by pushing a button on your iPhone, iPad or iPod Touch.

Viper SmartStart 4.0 gives you fingertip control over the following features of your Viper remote start or security/remote start system:

- Lock/arm
- Unlock/disarm
- Remote car starter
- Trunk release
- Panic
- Aux channels

Viper SmartStart GPS lets you locate your vehicle or get notified via alerts if your kids go somewhere they aren’t supposed to, or drive unsafely.

How do you get Viper SmartStart? Just follow these three simple steps:

1) Download the free Viper SmartStart app
2) Get SmartStart installed in your car (see for more information and where to buy Viper SmartStart).
3) Set up your SmartStart account, and start using your SmartStart system.

That’s all there is to it!

Viper SmartStart also includes membership in the Viper Motor Club, providing convenient flat rate 24/7 access to our nationwide roadside assistance network. Just press a button in the app to get connected for towing due to breakdown or accidents, or assistance with a dead battery or flat tire.

Latest features:

- Convenient widget provides quick access to sending commands

- Two new dashboards added that allow you to pick the layout and features most important to you

- Enhanced remote start feedback: the app confirms the command and then follows it up a few moments later to let you know if the engine is running, or stopped (digital systems only). The details are provided right on the dashboard too, no need to check your status page all the time.

- Enhanced command feedback: Now when you send a command to your SmartStart system, the app provides the details for the command right on the dashboard and keeps them there in case you forget and want to check back later to confirm what happened. Doors locked at 8:30AM? Check! (all systems)

- Is my car secure when I remote start it? Yep, we've been doing this a long time. The car is started, but only you can drive it away.
- Can I control all of my cars with the same app? You bet, just install Viper SmartStart systems in your other vehicles and they will show up in the app automatically.
- What is Viper Motor Club? It's our roadside assistance program that is included with every SmartStart Secure service plan (requires user to sign up via mysmartstart web site).

Great Time & Money Saver and All Round Cool App!


This app (along with the accessories installed in your vehicle) is AMAZING! I live in the Midwest and as you can imagine it gets cold during the winter, I use the app to start my car, let it warm up and melt any ice from my windshield. I even leave my heated seats on to warm up before I get in the car. I save time in the mornings by using the app while I’m getting ready or gathering all my stuff together before I leave for the day, the car is warmed up and ready to go when I am. Additionally, I can easily find my car in a large parking lot without having to search for it the app lets me know exactly where my car is. I have even gone to an event and left my keys in the car and used the app to unlock it-saved money on having to get a locksmith! The coolest thing, I can start my car wherever I am, no need to stay within 1,000 feet like other remote starts, you can be in the next town over or another state for that matter and start the car. It’s GREAT and I highly recommend you get the app and accessories!!

Great concept but needs work


Over the last 10 years I’ve had 5 different cars with aftermarket remote starts and alarm systems from directed through their various brands. The DS4 plus now in 2018 was my hope to solve the extra key fob plus having Bluetooth sounds like a dream. Well it still needs work. Anything less than 30 feet with one wall in between the car and myself won’t allow Bluetooth to work. Doesn’t matter which app you try (Directed and Viper) still same result. Many failed attempts to start the vehicle. The watch app on the other hand... That 100% of time it’s launched it asked you to connect your watch to your phone. It’s always connected... never works unless you launch the watch app and wait and wait and maybe it will connect and the you can try to start, lock or unlock the vehicle but it’s probably not going to work. Needs more frequent updates. They DS4 plus is in a 2015 Subaru Outback.

My Two Cents


I love the app and the product. I have the Smart Start and Security package, and it really does work quite well. I would only throw out two negatives though: price and start time. I've never owned a vehicle that was "nice and warm" after 12 minutes without driving (the cut off time for the Smart Start). Realistically, it's warm after 2 starts. The signal is spotty at best at the vehicle. I’ve tried rebooting the app and starting giving the command to start multiple times, but the vehicle’s system is pretty regularly out of service. That would make it worthy of 2 stars; HOWEVER, the key fob starter has extremely long range, which will still work when the SmartStart app won’t connect with the vehicle. It needs improvements, but I still recommend the product.
