Keys and doors operates by operating each transmitter. B 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.

To delete old transmitter codes, program four transmitter codes into the system. If you have only one current transmitter, program it four times. If you have two current transmitters, program each one twice. If you have 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. Security system (if equipped) The security system helps to protect your vehicle and valuables from theft.
