PKE car alarm system

What is PKE? The system is referred to as ‘Passive’ as it does not require any action from the user. The passive keyless entry (PKE) is an automotive security system that operates automatically when the user carries the key in proximity to the vehicle, unlocking the door on approach or when the door handle is pulled and locking it when the user walks away or touches the car on exit. A PKE device can operate while stored in the user’s pocket or bag, unlike an active or RKE device, which requires the user to hold the device and push a button to lock or unlock the vehicle.
