Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Programming ignition keys
Ignition keys can be added or erased. A maximum of 6 key IDs can be programmed into the immobilizer control module. When programming a key, the control module identifies the relevant key and stores it in the control module memory.
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.
During programming, when the control module receives a code from one of the remaining keys, all previous keys are erased from the control module. Only the code from the last used key is stored. The remaining keys must be programmed into the control module again. This corrective action can only be carried out on keys previously programmed into the control module.
It is important therefore that the customer takes all the keys to the dealership.
