Simple Key is a new way for consumers to easily replace modern car keys. The consumer-friendly kit includes a replacement key, emergency key insert, and EZ Installer. The emergency key blade provides a way to unlock your vehicle when your remote's battery is drained. It can be cut at most hardware stores, car dealers, or automotive locksmiths. Use the included EZ Installer to quickly and easily pair your key with your car in just a few minutes, without having to go to the dealership for pairing. Works just like your OEM key. The EZ Installer is designed for single vehicle use. Once you use it on your vehicle, it cannot be used on another. This specific product has 3 button functions: Lock, Unlock, and Panic. An alternative button pad is also included for vehicles equipped with remote-start functionality.
