Replacing the batteries 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. 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 transmitters to your dealer for reprogramming of your remote entry system. This is necessary to prevent further unauthorized use of the lost transmitter. Additional transmitters may be purchased from your dealer (remote entry system will work with up to four transmitters). Return your existing transmitters to your dealer so the remote entry system can be reprogrammed with your new and existing transmitters. THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES.
