Safety

A smart key fob communicates constantly with the vehicle via radiofrequency waves. It transmits a low power signal that, upon pressing it, prompts the vehicle open doors and begin the engine.

Security

A few of the most advanced electronic features in today's modern vehicles are found in the key fob. These devices are capable of more than locking and unlocking doors or making chirping sounds to help motorists locate their car in parking spaces.
