A proximity key (also called a “smart key” or “intelligent key”) is an electronic fob used for keyless entry and ignition systems in vehicles. Proximity keys pair with push-button starters, enabling drivers to unlock, enter, and start their cars without removing the fob from their pockets or purses.

The “key” transmits low-frequency (LF) radio waves to communicate with a vehicle to lock and unlock doors and start the engine when within a short range. Antennae within the vehicle identify the rolling code radio pulse generator inside the fob.

Heated mirrors use a heating element similar to those used for rear window defrosters to melt snow and ice from your side mirror, helping maintain visibility. They eliminate the need to scrape your exterior side mirrors.
