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.
Deleting Old Transmitter Codes
The control unit of the keyless entry system has four memory locations to store transmitter codes, giving it the ability to operate with up to four transmitters. When a transmitter is lost, the lost transmitter's code remains in the memory. For security reasons, lost transmitter codes should be deleted from the memory.
To delete old transmitter codes, program four transmitter codes into the system. If only one current transmitter is available, program it four times. If there are two current transmitters, program each one twice. If there are three current transmitters, program two of them once and the third one twice. This process will leave only current transmitter codes in the system's memory.
