If your vehicle has this feature, you can lock and unlock your doors from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle.

With the remote keyless entry system, your vehicle will have an entry lighting feature. See "Entry Lighting" under Interior Lamps .

The following functions are available with the remote keyless entry system:

LOCK: Press LOCK to lock all doors.

UNLOCK: Press UNLOCK to unlock the driver's door. If the UNLOCK button is pressed again within five seconds, all remaining doors will be unlocked.

Matching Transmitter(s) to Your Vehicle

Each remote keyless entry transmitter is coded to prevent another transmitter from unlocking your vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any remaining transmitters with you when you go to your dealer. When the dealer matches the replacement transmitter to your vehicle, any remaining transmitters must also be matched. Once your dealer has coded the new transmitter, the lost transmitter will not unlock your vehicle. Each vehicle can have a maximum of two transmitters matched to it.

Battery Replacement

Under normal use, the battery in your remote keyless entry transmitter should last about two years.

You can tell the battery is weak if the transmitter won't work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it's probably time to change the battery.

Notice: When replacing the battery, do not touch any of the circuitry on the transmitter. Static from your body could damage the transmitter.

To replace the battery in the transmitter 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. For battery replacement, use a 3-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 tight 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. See "Resynchronization" following.

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.

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 for at least seven seconds.
  3. 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.
