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.

LOCK:  Press this button to lock all of the doors.

The turn signal lights will flash once to confirm that the doors have locked. The remote keyless entry system will not operate while the doors are open, the key is in the ignition or if the liftglass or hatch are not completely closed and latched.

UNLOCK:  Press this button once to unlock the driver's door. The turn signal lights will flash twice and the interior lamps will come on to confirm that the door has unlocked. If the UNLOCK button is pressed again within three seconds, all remaining doors will unlock. The interior lamps will stay on for 15 seconds or until the ignition is turned on. If the UNLOCK button is pressed and no door is opened, the doors will lock automatically after 30 seconds.

HATCH: Press this button for a few seconds to open the rear liftglass. If the ignition key is in the ON position, the liftglass cannot be opened by the HATCH button on the transmitter.

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 four transmitters matched to it.

Battery Replacement

Under normal use, the battery in your remote keyless entry transmitter should last about three 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, do the following:

  1. Insert a small 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 upward. For battery replacement, use a three-volt battery, type CR2032, or equivalent.
  3. Snap the transmitter back together tightly to be sure no moisture can enter.
