Car Access

Microchip offers traditional Remote Keyless Entry (RKE), Passive Entry Passive Start (PEPS) and immobilizer car access solutions. RKE uses key fob push-button access, while PEPS enables a more advanced hands-free interaction with the vehicle. PEPS provides locking, unlocking and engine start/stop functionality over high-security channels without any manual action with the key fob. Individual key fobs can be customized for drivers, adjusting seat and mirror positions, car's infotainment settings and more. PEPS allows an autonomous and convenient way to enter and start the vehicle while maintaining a high level of safety and security. Both RKE and PEPS solutions work with immobilizer technology enhancing security and providing dead-battery fob access.
