The vehicle's doors can be locked and unlocked, or the trunk can be unlocked from about 3 feet (1 m) up to 30 feet (9 m) away with the remote keyless entry transmitter.

LOCK: Press the LOCK button to lock all the doors. Pressing the LOCK button may arm the content theft-deterrent system. See Content Theft-Deterrent for more information.

UNLOCK: Press the UNLOCK button once to unlock the driver's door. Press the UNLOCK button again within five seconds to unlock the other doors. Pressing the UNLOCK button on the remote keyless entry transmitter will disarm the content theft deterrent system. See Content Theft-Deterrent for more details.

(Remote Alarm): Press the remote alarm button to activate an alarm. The ignition must be in off or accessory for the remote alarm to work. When the remote alarm button is pressed the headlamps will flash and the horn will sound repeatedly. The alarms will turn off when the ignition is moved to run or the remote alarm button is pressed again.

(Trunk Release): Press this button to release the trunk lid. The transaxle must be in PARK (P) for this feature to operate.

The vehicle may have Remote Lock/Unlock Confirmation. This feature provides feedback that a command has been received by the vehicle. The headlamps will flash and the horn may sound briefly. See "Remote Lock Feedback" under DIC Controls and Displays for programming information.

Matching Transmitter(s) to Your Vehicle

Each remote keyless entry transmitter is uniquely coded to prevent another transmitter from unlocking the vehicle. If a transmitter is lost or stolen, a replacement can be purchased through your dealer. Remember to bring any additional transmitters so they can also be re-coded to match the new transmitter. Once your dealer has coded the new transmitter, the lost transmitter cannot unlock the vehicle. The vehicle can have a maximum of four transmitters coded to it.

Battery Replacement

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

If the battery is weak the transmitter will not work within its normal range. It is probably time to change the battery If you have to be very close to the vehicle before the transmitter works.

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 flat object like a thin coin into the notch, located below the trunk release button, and pry the front and back apart.
  2. Remove the old battery, but do not use a metal object to do this.
  3. Slide the new battery into the transmitter. Use a type CR2032 battery, or equivalent type.
  4. Snap the front and the back of the transmitter together.
  5. Resynchronize and test the operation of the transmitter with the vehicle.

Resynchronization

If the functions on the remote keyless entry transmitter do not work, or, if only the remote alarm works, after the battery is replaced, then the transmitter needs to be resynchronized to the receiver. Do this by pressing and holding the LOCK and UNLOCK buttons on the transmitter at the same time for about eight seconds.

To verify that the transmitter has been resynchronized, the horn will sound and the exterior lamps will flash once.
