- Transponder Keys: Introduced in the mid-1990s, these secrets feature a plastic head consisting of a small computer chip. Even if the metal is cut correctly, the car will not start unless the chip is set to the lorry's ignition.
- Remote Keyless Entry (RKE) Fobs: These are portable devices that permit for locking and unlocking doors through radio waves. In lots of older designs, the fob is separate from the mechanical key.

The Programming Process: Why It's Complex

- Examine the Battery First: Often, a "dead" key is merely a dead CR2032 battery. Replacing the battery for ₤ 5 can conserve a ₤ 300 journey to the dealer.
