UNLOCK: When you press the UNLOCK button, only the driver's door will unlock. If you press UNLOCK again within five seconds, all the doors will unlock. If you would like all the doors to unlock the first time you press UNLOCK, see Power Door Locks on page 2-9 The UNLOCK button on the remote keyless entry transmitter will disarm the content theft deterrent system. See Content Theft-Deterrent on page 2-75 for more details. 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. (Open Trunk): Press the button with the trunk symbol to open your trunk. The transaxle must be in PARK (P) for this feature to operate. (Remote Alarm): When you press the button with the horn symbol, the headlamps will flash and the horn will sound. This will allow you to attract attention if needed. Your vehicle may have Remote Lock/Unlock Confirmation. This feature provides feedback to the holder of the remote keyless entry transmitter that a command has been received by the keyless entry receiver. To signal that a command has been received, the headlamps will flash and the horn may sound briefly. See Vehicle Personalization on page 2-43 for programming information. .& 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.
