Passive Entry Passive Start (PEPS Fob)

Automotive Security System Solutions from Texas Instruments


Car access functions enable entry into the car and starting the engine. Immobilizer system specifically allows the driver to start the engine or the motor using the correct key. Remote Keyless Entry (RKE) allows for entry into the car using the correct keyfob. The more advanced Passive Entry Passive Start (PEPS) system enables unlocking the car door for entry and starting the engine with a keyfob that uses wireless low frequency and high frequency signals to communicate with car access control units. In order to unlock the door or the trunk, PEPS systems detect the presence of a keyfob based on the driver touching the door handle of the car or kicking her foot under the trunk. Car access systems also include key pad installed on the door that allow access when the driver enters specific code on the keypad.
