To replace the battery in the keyless entry system, do the following: 1. Use a coin or similar object to separate the bottom half from the top half of the transmitter. 2. Remove the battery and replace it with the new one. Make sure the positive (+) side of the battery faces down. Use one three-volt, CR2032, or equivalent, type battery. 3. Put the two halves back together. Make sure the cover is on tightly, so water won't get in. 4. Check the operation of the transmitter with your vehicle. If the transmitter does not work, try resynchronizing the transmitter with the receiver. Resynchronization Your keyless entry system is equipped with a security system that prevents anyone from recording and playing back your signal. The transmitter does not send the same signal twice to the receiver. The receiver will not respond to a signal that has been sent to it more than once. To synchronize your transmitter and receiver, follow these directions: 1. Stand close to your vehicle. 2. Press and hold the LOCK and UNLOCK buttons on the transmitter at the same time. 3. Hold the buttons for five seconds. In this time, the doors should lock and unlock once. This confirms the resynchronization. If the doors do not lock and unlock, see your dealer for service. Trunk To unlock the trunk from the outside, insert the key and turn the trunk lock cylinder. When closing the trunk, close from the center to ensure it fully latches. 2-14
