key fobs
Pocket entry devices
Key fobs are small devices attached to keychains, originally decorative ornaments but now typically electronic transmitters for remote locking and unlocking vehicles or buildings.
The fob communicates wirelessly when you press a button or approach the lock: I left my key fob in the car.
Some fobs also start engines remotely.
