You can lock and unlock your doors and cargo area from about 3 feet (1 m) up to 30 feet (9 m) away using the remote keyless entry transmitter supplied with your vehicle.

(Unlock):  When you press unlock, the driver's door will unlock automatically, the parking lamps may flash, the horn may sound, and the interior lights will turn on.

If your vehicle has the memory seat feature and you have previously programmed a seat position, the driver's seat will move to that position when you press the unlock button. See Memory Seat for more information.

[block ] (Lock): Press lock to lock all the doors. Press lock again within three seconds and the horn will chirp.

(Cargo Cover Release): To release the cargo cover, press the button with this symbol on it. The convertible top must be all the way up or down for this feature to work properly. See "Roof Tonneau" under Lowering the Convertible Top for more information. The cargo cover can also be released using the cargo cover release button located in the glove box. See Cargo Cover for more information.

(Remote Alarm):  Press the button with the horn symbol on it, to sound the horn and make the headlamps and taillamps flash for up to 30 seconds. This can be turned off by pressing the horn button again, or by waiting for 30 seconds, or by starting the vehicle.

You can program different feedback settings for up to two drivers using the Driver Information Center (DIC). For more information see Driver Information Center (DIC) .

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 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.

The Driver Information Center (DIC) will display a Rfa X Battery Low message when the transmitter battery is low. See DIC Warnings and Messages .

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 remote keyless entry transmitter, do the following:


Object Number: 807792  Size: B3
  1. Insert a thin coin in the slot between the covers of the transmitter housing. Gently pry the transmitter apart.
  2. Remove and replace the battery with a three-volt CR2032 or equivalent battery.
  3. Align the covers and snap them together.
  4. Check the operation of the transmitter.
