The Passive Keyless Entry (PKE) system provides the user with the convenience of communicating with a RKE/immobilizer/security system without pressing any buttons.
This reference design contains three boards:
- Base Station – Initiates communication by sending out a Low Frequency signal between fixed time intervals to search for the paired Key Fob.
- Key Fob – When the Key Fob detects the signal it sends back an Ultra High Frequency acknowledgment signal.
- Receiver/Decoder – Receives the signal sent out by the Key Fob, and upon positive authentication, signals for the door to be unlocked.
