Deleting old transmitter codes

The control unit of the remote keyless entry system has four memory locations to store transmitter codes, giving it the ability to operate with up to four transmitters.

When you lose a transmitter, the lost transmitters 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 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 systems memory.

NOTE
Make sure no one else is operating their keyless entry system within range of your vehicle when programming transmitters. If someone else were to operate their remote transmitter while you are programming your transmitters, it is possible that their transmitter code will be programmed into your system, allowing them unauthorized access to your vehicle.
