PKE REMOTE Car Key Remote

The PKE key fob and the vehicle module both contain transceivers that communicate wirelessly to detect each other.
The module in the vehicle continually sends out encoded messages; when the key fob is in range it responds.
If the encrypted messages are correct, they identify the vehicle and key fob to each other and the door opens.
Current PKE REMOTE systems often use rolling codes to ensure that a fresh code is supplied each time, preventing the possibility of a replay attack.

Cars that are designed for passive keyless entry often feature keyless start as well, which simply requires the driver to push a button.
(That combination is sometimes called passive entry/passive start or PEPS.)
Individual smart keys may be customized for specific drivers, adjusting seat and mirror positions automatically, for example, or setting the car's radio to the driver's chosen station.
