Car keys explained: basic, transponder, remote and smart keys
Modern car keys are small computers. Knowing which type you have helps you understand what a replacement involves.
Basic metal key
- Found on older vehicles. Cut to the lock, no programming.
- Usually the cheapest and quickest to copy.
Transponder key
- Contains a chip that the car recognises before it will start.
- A replacement has to be cut and programmed to the vehicle.
Remote head key and flip key
- Combines a transponder key with lock and unlock buttons on the same head.
- Needs cutting, chip programming and remote programming.
Smart key and proximity fob
- Lets you unlock and start the car without inserting the key.
- Needs to be programmed to the vehicle, and the cost depends on the make and model.
- Even a smart key usually has a hidden emergency key blade.
