a vehicle with children.
WARNING!
Leaving children in a vehicle with 
the Remote Keyless Entry (RKE) 
transmitter is dangerous for many 
reasons; children or others could 
be badly injured or even killed.
They could operate the power 
windows or other controls or even 
make the vehicle move. The 
windows will function with the 
RKE transmitter in the vehicle 
and they could be seriously 
injured or killed if caught in the 
path of a closing window. Do not 
leave the RKE transmitter in a 
vehicle with children.

The key that is part of the Remote Keyless Entry (RKE) transmitter can be used for the ignition and all locks if the vehicle is a key access vehicle. If the vehicle has the keyless ignition, the key can be used for the locks.

Press the button on the RKE transmitter to extend the key. Press the button and the key blade to retract the key.
See your dealer if a new key is needed.
Notice:
If the keys get locked in 
the vehicle, it may have to be 
damaged to get them out. Always 
carry a spare key.
If locked out of the vehicle, see Roadside Assistance Program (U.S.
and Canada) or Roadside Assistance Program (Mexico).
With an active OnStar subscription, an OnStar Advisor may remotely unlock the vehicle. See OnStar Overview.
Remote Keyless Entry (RKE) System
See Radio Frequency Statement for information regarding Part 15 of the Federal Communications Commission (FCC) rules and Industry Canada Standards RSS-GEN/210/220/310.
If there is a decrease in the RKE operating range:
• Check the distance. The transmitter may be too far from the vehicle.
• Check the location. Other vehicles or objects may be blocking the signal.
• Check the transmitter's battery.
See “Battery Replacement” later in this section.
• If the transmitter is still not working correctly, see your dealer or a qualified technician for service.
Remote Keyless Entry (RKE) System Operation
The transmitter functions will work up to 20m(65 ft) away from the vehicle. On vehicles with remote start the distance will be greater.
Keep in mind that other conditions, such as those previously stated, can impact the performance of the transmitter.

Keyless Access Operation
Some vehicles have a keyless access system that lets you lock and unlock the doors and access the trunk without removing the RKE transmitter from your pocket, purse, briefcase, etc. The RKE transmitter should be within 1m(3 ft) of the door or trunk being opened.
Keyless Unlocking
With the RKE transmitter within 1m(3 ft), approach the front door and pull the handle to unlock and open the door. If the transmitter is recognized, the door will unlock and open.
Entering any door other than the driver door will always cause all of the doors to unlock. This is not customizable.
To customize which doors unlock when the driver door is opened, see “Door Unlock Options” under Vehicle Personalization.

Programming Transmitters to the Vehicle
Only RKE transmitters programmed to the vehicle will work. If a transmitter is lost or stolen, a replacement can be purchased and programmed through your dealer.
The vehicle can be reprogrammed so that lost or stolen transmitters no longer work. Any remaining transmitters will need to be reprogrammed. Each vehicle can have up to five transmitters matched to it.
Programming with a Recognized Transmitter (Keyless Access Vehicles Only)
A new transmitter can be programmed to the vehicle when there is one recognized transmitter.
To program, the vehicle must be off and all of the transmitters, both currently recognized and new, must be with you.
1. Place the recognized transmitter(s) in the cupholder.
2. Insert the vehicle key of the new transmitter into the key lock cylinder located on the outside of the driver door and turn the key to the unlock position five times within 10 seconds.
The Driver Information Center (DIC) displays READY FOR REMOTE #2, 3, 4 or 5.
3. Place the new transmitter into the transmitter pocket. The transmitter pocket is located inside the center console storage area under the cupholder. The cupholder will need to be pulled out to access the transmitter pocket.
4. Press the ignition. When the transmitter is learned, the DIC will show that it is ready to program the next transmitter.

If there are no currently recognized transmitters available, follow this procedure to program up to five transmitters. This feature is not available in Canada. This procedure will take approximately 30 minutes to complete. The vehicle must be off and all of the transmitters you wish to program must be with you.
1. Insert the vehicle key of the transmitter into the key lock cylinder located on the outside of the driver door and turn the key to the unlock position five times within 10 seconds.
The Driver Information Center (DIC) displays REMOTE LEARN PENDING, PLEASE WAIT.

The DIC display should now show READY FOR REMOTE # 1.
4. Place the new transmitter into the transmitter pocket. The transmitter pocket is located inside the center console storage area under the cupholder. The cupholder will need to be pulled out to access the transmitter pocket.
5. Press the ignition. When the transmitter is learned the DIC will show that it is ready to program the next transmitter.
6. Remove the transmitter from the 
transmitter pocket and press  .

The battery is not rechargeable. To replace the battery:
1. Push the button on the transmitter to extend the key.
2. Remove the battery cover by prying it with a finger.
3. Remove the battery by pushing on the battery and sliding it toward the key blade.

See “Remote Start Climate Control Operation” in Automatic Climate Control System or Dual Automatic Climate Control System. Vehicles with heated or heated and ventilated front seats can have this feature turn on automatically during a remote start.
See “Remote Start Heated Seats” and “Remote Start Cooled Seats” under Vehicle Personalization for more information.
Extending Engine Run Time
The engine will continue to run for 10 minutes. Repeat the steps for a 10-minute time extension. Remote start can only be extended once.
When remote start is extended, the second 10 minutes will start immediately.
For example, if the vehicle has been running for five minutes, and 10 minutes are added, the engine will run for a total of 15 minutes.
A maximum of two remote starts or remote start attempts are allowed between ignition cycles.

Door Locks
WARNING!
Unlocked doors can be 
dangerous.
• Passengers, especially 
children, can easily open the 
doors and fall out of a moving 
vehicle. The chance of being 
thrown out of the vehicle in a 
crash is increased if the 
doors are not locked. So, all 
passengers should wear 
safety belts properly and the 
doors should be locked 
whenever the vehicle is 
driven.
• Young children who get into 
unlocked vehicles may be 
unable to get out. A child can 
be overcome by extreme heat 
and can suffer permanent 
injuries or even death from 
heat stroke. Always lock the 
vehicle whenever leaving it.
• Outsiders can easily enter 
through an unlocked door 
when slowing or stopping the 
vehicle. Lock the doors to 
help prevent this from 
happening.
To lock and unlock the doors from the outside, use the Remote Keyless Entry (RKE) transmitter or the key.
To lock the doors from inside, use the power door lock switch or door lock knob. To unlock the doors, use the power door lock switch or pull once on the door handle to unlock it, and a second time to open it.
Manually locking the driver door also automatically locks all other doors.
