VIPER SRT

The Good The Viper SmartStart and SmartKey system adds hands-free unlocking to cars along with the ability to remotely lock or unlock the doors from anywhere in the world. GPS features show where you parked and let you share your car's location with family and friends.
The Bad Remote unlocking or locking with the app, through the data connection, takes much longer than with a key or Viper's included RF fob. Setting the Bluetooth proximity unlocking for SmartKey requires a lot of trial and error.
The Bottom Line While Bluetooth proximity unlocking and the GPS locator features of Viper SmartStart and SmartKey come in handy, it is a fairly big installation and will apply to limited scenarios and vehicles.
