If the code matches the kept recommendation, the engine is permitted to begin. This included a layer of anti‑theft protection and significantly lowered the incidence of hot‑wiring.
Remote Keyless Entry (RKE) Fobs
RKE fobs integrate a mechanical key blade with a radio transmitter. Pushing a button sends out an encrypted RF signal to lock/unlock doors and, in numerous designs, to open the trunk or trigger a panic alarm.
