Secure-A-Key Is an anti-theft device
Designed to prevent Passive Keyless Entry and Push-to-Start vehicle theft.
Thieves can steal Push-To-Start cars by using a device to capture the frequency and data of the vehicle's remote key fob, then transmit the data over a far distance to your vehicle; this will allow the thieves to unlock your vehicle, start the engine and drive it away without setting off traditional alarms or your knowledge.
Secure-A-Key disables your vehicle's remote key fob when it is not actively being used, preventing theives from capturing its signal while your at home or work. It does this by detecting motion and cuts all power to the fob when no motion has been detected in 5 minutes.
