A FORD technician has left drivers stunned after revealing a hidden button that enables programming for a personal keyless entry code.

The Ford SecuriCode touchpad feature is only offered by the Dearborn automaker and lets drivers in without a key.

Thieves target cars with keyless entry, using relay box equipment that can pick up the signal from the key fob while it's in the owner’s home. They then use the key's code to open and start the car.
