Because the late 1990s, manufacturers have integrated transponder chips into car keys as a deterrent versus "hot-wiring." When request quote into the ignition or brings a clever key into the cabin, the car sends out a radio frequency signal to the key. The key needs to then react with a distinct digital code.

Every car has a special security code or "PIN" (frequently called an Immobilizer Code). For lots of makes and models, the programmer needs to extract this digital code from the ECU before a new key can be added.
3. Deleting Old Keys (Optional but Recommended)
If a key was stolen or lost in a public London park or street, the technician can wipe the car's memory of all previous keys. This ensures that the lost key can no longer begin the engine, supplying the owner with comfort.

Lastly, the buttons for locking and opening the doors are set. This is often a different digital process from the transponder programming.
