You can lock and unlock your doors and the liftgate 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 on the remote keyless entry transmitter, only the driver's door will unlock. If you press UNLOCK again within five seconds, all the doors and the liftgate will unlock. If you would like all the doors to unlock the first time you press UNLOCK, see Vehicle Personalization . With the content theft-deterrent system, the UNLOCK button on the remote keyless entry transmitter will disarm the system. See Content Theft-Deterrent for more details. When you use your remote keyless entry transmitter to unlock your vehicle or to operate the power sliding door(s), the parking lamps will flash to let you know the command was received. If you would like to change the way the parking lamps operate with remote unlock confirmation, see Vehicle Personalization .

LOCK: To lock all doors, press LOCK on the remote keyless entry transmitter. See Power Door Locks for more details on the power door lock features. With the content theft-deterrent system, the LOCK button may arm the system. See Content Theft-Deterrent for more details. When you use the remote keyless entry transmitter to lock your vehicle, the parking lamps will flash to let you know the command has been received. If you press the LOCK button again, within five seconds, the horn will sound and the parking lamps will flash to let you know the vehicle is already locked. If you would like to change the way the parking lamps and horn operate with remote lock confirmation, see Vehicle Personalization .

Remote Alarm

When you press the horn button on the remote keyless entry transmitter, the parking lamps will flash and the horn will sound. This will allow you to attract attention, if needed.

Press this button again to stop the alarm from sounding.

Remote Power Sliding Door Operation

If your vehicle has the power sliding door, your remote keyless entry transmitter will have a button that has a van symbol on it. Press it to open or close the sliding door. See Power Sliding Door (PSD) .

If your vehicle has the dual power sliding doors, your remote keyless entry transmitter will have two buttons that have a van symbol on them. The van symbol on the left is for the driver's side sliding door and the van symbol on the right is for the passenger's side sliding door. See Power Sliding Door (PSD) .

If the power sliding door(s) is locked, first unlock all doors, then press the van symbol to open the power sliding door(s). The parking lamps will flash when the right button with the van symbol is pressed and they will not flash when the left button with the van symbol is pressed. Press the van symbol again to close the sliding door(s). See Power Sliding Door (PSD) for more information.

You can operate the power sliding door(s) with the remote keyless entry transmitter only when the power sliding door override switch(es) on the overhead console is turned off. See Power Sliding Door (PSD) .

If your vehicle's fuel filler door is opened, the driver's side power sliding door will not open completely. Do not try to force the door. Once the fuel filler door is closed, the driver's side sliding door can be opened normally.

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.

See your dealer to match transmitters to another vehicle.

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 will not work at the normal range in any location. If you have to get close to your vehicle before the transmitter works, it is 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.

  1. Insert a flat object, such as a coin, into the slot on the side of the transmitter and twist it to separate the halves.

  5. Reassemble the transmitter. Make sure the halves are snapped together tightly so water will not get in.
  6. Press and hold the LOCK and UNLOCK buttons for seven seconds to synchronize the transmitter.
  7. Check the transmitter operation.
