- Rolling code-- In RKE and clever secrets, the code modifications with each use to prevent thieves from recording and replaying the signal.
When the motorist presses a button, the fob sends a coded signal to the car's receiver. If the code matches, the door locks (or the ignition) engage. Some systems also use low‑frequency (LF) signals for proximity detection, making it possible for "hands‑free" entry and ignition.

- Rolling code encryption: Prevents "code grabbing" attacks where thieves capture a signal and recycle it.
- Encryption of keyless signals: Advanced AES‑256 encryption is utilized in lots of modern-day clever secrets to obstruct relay attacks.
- Physical reinforcement: Some keys include an enhanced steel shaft to resist forced extraction.
Owners can further boost security by:
- Storing spare type in a shielded pouch to obstruct RFID signals.
- Utilizing a guiding lock or wheel lock when parked in high‑risk locations.
