This electronic system uses a radio frequency fob to broadcast an encrypted signal to the vehicle's receiver. When authenticated, the body control module triggers the door actuators to open or secure the latches. It eliminates the need to insert a physical blade into the door cylinder and often includes controls for the trunk, alarm, and panic functions.
Heard on the job
I programmed the new fob, but the remote keyless entry still won't actuate the driver door lock.
Insider tip
If the system stops working suddenly, check the coin battery in the fob before tearing into the door panels.
