Programming Ignition Keys
Ignition keys can be added or erased. When programming keys for a vehicle, the transponder and remote control are programmed at the same time. A maximum of 6 transponder IDs and their remote controls can be programmed into the vehicle. The transponder and remote control IDs are stored in the central electronic module (CEM) in cars without the keyless entry system. In cars with the keyless entry system, only the transponder ID is stored in the central electronic module (CEM). The remote control ID and ID of the keyless function is stored in the keyless vehicle module (KVM).
When programming keys, codes stored in the relevant control module memory are used to identify the key and remote control.
The erase function is used when the customer wishes to prevent one or more keys from being used to start the vehicle. The keys may have been stolen and could be traced back to the vehicle.
The ignition key and remote control are integrated. Therefore the codes for the remote control, keyless function (if applicable) and transponder must be available when programming. If adding a key with passive functionality, three codes must be programmed into the vehicle. These codes are programmed at the same time. This means that a key that has been removed can be programmed back to the same vehicle if all of these codes are available. The codes can be found on the packaging in which the keys are delivered. If the codes are not available, a new ignition key must be ordered. The remote controls are identical in appearance, only the internal functionality differs. Ensure that the "correct" remote control is programmed into the correct vehicle.
Keys are programmed via the Software Manager.
