Unlocking the potential of keyless innovations

Advancements in automotive technologies continue to make driving safer, simpler and easier. Passive Keyless Entry and Start, in particular, is an innovation now enjoyed by many drivers of modern vehicles. By emitting a low power signal, the system senses our proximity to our cars, allowing us to open car doors and start our engines without the need to reach for our keys. 

The ingenuity behind this innovation lies in the smart communication between the passive key and a vehicle’s electronic control unit. At Avnet, we enable this intelligent technology and advance it even further through extremely compact single chip solutions that provide immobilisation functions as well as incorporate Security Transponder, RISC Controller and UHF Transmitter on the same chip while requiring only a few external components.
