Replacing the Battery in the Remote
Keyless Entry System Transmitter
To replace the battery in the transmitter:
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. For battery replacement, use a three
- volt
battery, type CR2032, or equivalent.
3. Read the instructions inside the case.
4. Put the two halves back together. Make sure the
cover is on tightly, so water won’t get in.
5. Check the operation of the transmitter with your
vehicle. If the transmitter does not work, try
resynchronizing the transmitter with the receiver.
Resynchronization
Your remote 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.
Normally, the transmitter and receiver resynchronize
automatically. However, under certain circumstances,
manual resynchronization may be required.
To resynchronize 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 at least 10 seconds. During
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.
