The buttons on your key allow you to lock and unlock your doors or unlock your trunk.

When pressing the key buttons, ensure that other keys on the key ring are not between the main key and the vehicle. Other keys can obscure the signal being transmitted to the vehicle.

When a button on the key is pressed, it sends a signal to the vehicle. The receiver of the signal is a small rectangle centered on top of the dashboard. The receiver is also used to measure sunlight. It is important that the receiver is clean, not covered, and that there are no metal objects close by, as this may block the signals.

LOCK: Press this button on the key to lock all the doors, disable the engine, and set the alarm. The vehicle's turn signals will briefly flash. If you prefer to have the turn signals flash accompanied by the horn sounding, the LOCK feature can be changed. See Vehicle Personalization . The LOCK button on the key will not work if the ignition is turned on, or if the driver's and/or passenger's door is open. Prior to locking your vehicle, make sure all the doors are closed completely. If the LOCK button is pressed when a door is open, the horn will sound three times to indicate that a door has not locked. Close the open door and reset the remote system by first pressing the UNLOCK button and then the LOCK button on the key.

UNLOCK: Press this button on the key to unlock the doors. The turn signal lamps will flash twice, and the horn will chirp twice, if this unlocking option is selected through vehicle personalization. The interior light will also turn on for a short time. If UNLOCK is pressed once, the driver's door will unlock. If UNLOCK is pressed a second time, or is held down for more than half a second, all the doors will unlock. If you prefer to have all the doors unlock with a single press, the unlock feature can be changed to unlock all doors. See "Two Stage Unlock" under Vehicle Personalization . If the lock system is overloaded as a result of repeated use in a short time interval, the power supply is cut off for about 30 seconds. The door lock system has been designed to make the vehicle horn chirp rapidly five times if it detects a fault in the lock system when the LOCK button is pressed. You should check to see that the doors have locked.

(Trunk): Press and hold this button for approximately one second to release the trunk lid. The trunk button on the key will not work if you are travelling over 12 mph (20 km/h).

Battery

The key has a non-removable battery. Under normal use, the battery in your key should last about five years.

You can tell the battery is weak if the key will not work at the normal range in any location. If you have to get close to your vehicle before the key buttons work, it is probably time for a replacement key. See your dealership to purchase a replacement key.

If the buttons on the key are not working at the normal range in any location, insert the key into the ignition and turn it ON and then OFF. Remove the key from the ignition and try pressing the LOCK and UNLOCK buttons again. If it still does not work a replacement key may be needed. You will have to go to the dealership to purchase a replacement key.
