Replacing the Batteryin the Remote Transmitter 1. Insert a flat object like a dime into the slot on the side of the transmitter and twist to separate the halves. 4. Reassemble the transmitter. Make sure the halves are snapped together tightly so water will not get in. 5. Check the transmitter operation. If needed, follow the instructions on resynchronizing your remote transmitter. Resynchronizing Your Remote Transmitter Your remote lock control system uses a continually changing code for increased security. Normally, the receiver in your vehicle will keep track of this changing code. Loss of synchronization will occur if the transmitter is activated more than 256 times while out of range of the vehicle. Loss of synchronization will occur after the battery replacement if the transmitter is immediately activated more than 16 times while out of range of the vehicle. 2. Gently pry the battery out of the transmitter. Do not use the metal flanges to "pop out" the battery. If your remote lock control transmitter has stopped working, you may need to resynchronize the transmitter to the vehicle receiver.To do this, press the LOCK and UNLOCK buttons together and hold for at least seven seconds or until the horn sounds if equipped with Content Theft-Deterrent. Check the transmitter operation. 3. Replace the battery. 2-12
