Because they do not include the "handshake" technology needed to start the engine, they are generally the easiest and most inexpensive to replace.
2. Transponder Keys
Introduced in the mid-1990s, these secrets feature a plastic head housing a little microchip. Although the key should be physically turned in the ignition, the engine will not start unless the car's computer system receives a specific digital signal from the chip. This prevents "hotwiring."
3. Switchblade Keys
These fobs integrate the remote locking buttons with a mechanical key that folds into the fob body. They are common with European manufacturers like Volkswagen and Audi. The replacement needs both specialized laser cutting for the blade and electronic programming for the remote.
4. Smart Keys (Proximity Fobs)
Smart secrets represent the peak of existing entry technology. These fobs do not need a physical key to be inserted into a slot. As long as the fob remains in the motorist's pocket or purse, the car can be opened through a button on the door handle and started with a "Push to Start" button.

Every time the fob is pressed, it creates a new code that the car expects to see next. This prevents "relay attacks" where burglars catch a signal to use later on.
Professional programming involves:
- Connecting to the OBD-II Port: A specialist uses a specialized computer system connected to the lorry's diagnostic port.
- Clearing Old Data: If keys were lost or stolen, the old IDs are cleaned from the lorry's memory.
- Syncing the Transponder: The vehicle is put into a "discovering mode" where it acknowledges the unique identification number of the new chip.
- Evaluating Features: Ensuring the trunk release, remote start, and distance sensing units all work in harmony.
