electronic key
Keyless entry device
An electronic key is a device that uses digital signals rather than physical notches to unlock something—typically a car or building.
The key communicates wirelessly with the lock, often through radio frequency or Bluetooth: I just keep the electronic key in my pocket and the car unlocks when I approach.
Also called a key fob or smart key.
