The transmitter can be snapped apart to replace the batteries by twisting a thin coin between the two halves of the transmitter. DO NOT TAKE THE FRONT PART OF THE TRANSMITTER APART. Carefully remove the old batteries. When installing the new batteries, be sure to place the positive (+) side down as marked. Snap the two halves back together. Replacement/additional transmitters In the event a transmitter is lost, return the remaining transmitter(s) to your dealer for reprogramming of your remote entry system. This is necessary to prevent unauthorized use of the lost transmitter. Additional transmitters may be purchased from your dealer (remote entry system will work with up to four transmitters). Follow the same programming procedure as above. All transmitters must be programmed (or reprogrammed) at the same time. If the programming mode is entered and the transmitters are not programmed (or reprogrammed) at the same time, they will not operate with the system. 88
