keyfob
Pocket unlock button
A keyfob is a small electronic device carried on a keychain that transmits a signal—typically to lock or unlock a car, open a garage door, or grant building access.
The term combines key with fob, an ornament attached to a watch chain or keyring.
Modern keyfobs often allow remote engine start or proximity-based keyless entry: I left my keyfob in the car.
