If you have lost your keys, or have just bought a new car, you will need to program a new keyless remote. There are three broad categories when it comes to GM keyless remotes: pre-2007, 2007–10 with VIC, and 2007 – 10 without VIC. If your car is a GM post-2010 model, you should contact your nearest car care professional. After 2011, most GM models have already synced transmitters that come with the car when you buy it. Once you determine which category your car fits in, programming a keyless remote becomes a very easy process, only involving a few quick steps. Set aside a few minutes of your time, and you will never have to use an old-fashioned key again!

Steps

Programming for Pre-2007 GM Models

Get inside of your vehicle. It is necessary for you to be near both the inside locks and the ignition. Make sure you are sitting comfortably in your seat, and that the keyless remote is close enough to the steering wheel and locks.

Close all the vehicle doors. Make sure that each door is shut tightly, otherwise the vehicle will not sync correctly. If you can, give each door handle a yank from the inside to make sure that they are closed as tight as they can be.

Insert the ignition key into the ignition lock cylinder. However, do not turn ignition switch yet. This will screw up the cycle you will have to start over.

Press and hold the driver door unlock switch. This is the switch on the door, not the remote. Do not let up on the lock, otherwise it will mess up the process and force you to restart.

While holding the door lock switch in the unlock position, cycle the ignition ON, OFF, ON, OFF, ON, OFF. Only turn the key as far as it will go before the ignition actually starts the engine. You do not want to start your car. Every time you turn the key to the ON position, a light on the dashboard should appear, and then go away when you turn the key to the OFF position. Do this step quickly.

Release the door unlock switch. The doors will lock and unlock one time to confirm the program mode is activated. If the door only locks, or only unlocks, you will have to start the process over again. Something likely went out of sync, or you did not turn the ignition ON/OFF fast enough.

Simultaneously press and hold the lock button and the unlock button on the keyless remote for fifteen seconds. The doors will lock and unlock as you are holding down both buttons to confirm the programming of that transmitter. Do not wait to do this step. You want to do this within ten to twenty seconds after you have shifted the ignition ON/OFF.

Repeat the previous step to program up to four transmitters. Once more, do not wait very long in between transmitters. Otherwise you will lose the sync with your car and have to start the process all over again.

Turn the ignition switch to the ON (one more click forward) position in order to exit the keyless entry transmitter mode. If you forget to do this step, it is likely that your car will not unlock/lock properly.

Operate the transmitter functions in order to verify correct system operation. Step out of your car, and go as far as 20 feet. Test the locking mechanism on the transmitter. If it works from that distance, step back another 20 feet (40 feet in total) and try it from there. If you are noticing it not working, you may have to restart the sync cycle over again. It may also indicate the battery is low.

Determine if your car has a VIC (Vehicle Identity Check). Common places to look are in your driver's manual which comes with the car. You can ask your car care professional. There should also be a Vehicle Information button on your dashboard with a picture of a car, marked with the letter "I". If your car has a VIC, use the following steps.

Get in your car. Sit down comfortably in the driver's seat, and make sure that all of the doors are closed. Tug on each of the handles from inside to make sure they are all closed tight. Make sure that your transmitter is close to the steering wheel and lock buttons.

Start your car. Put your key in the ignition and turn it all the way clockwise until you hear the engine come on. Make sure that the gear shift is set to park.

Press and hold the Vehicle Information button until the display reads "Press V to Relearn Remote Key." If for some reason the display does not appear, restart your car, and repeat the previous steps. If the display still does not appear, contact your nearest GM car care professional.

Press the Set/Reset button until "Remote Key Learning Active" appears on the display. The Set/Reset button should be near the Vehicle Information button. If you cycle past the option, continue pressing the Set/Reset button until the "Remote Key Learning Active" option reappears.

Press and hold the Lock and Unlock buttons at the same time. Do this for at least fifteen seconds. You should hear a noise that sounds like a chime. This means that your transmitter has been successfully synced. If that does not happen, it is likely the sync is off, in which case you will have to restart the process.

Repeat the previous step for each transmitter, up to four. Do this in rapid succession. If you wait too long, it is likely that your car will go out of sync, and you will have to restart the process for whichever transmitters you have left over.

Exit programming mode by turning off the vehicle and removing the key. It is important that you do this, otherwise the lock/unlock features in your car will not properly work. This can result in dangerous circumstances where your locks do not work. If you forget, or take too long to take your key out, start the whole process over again for your own safety and convenience.

Test your transmitters. Get out of your car and close the driver's door. Step away from the car about 20 feet. Press the unlock/lock buttons separately. If they work from this distance, step back to a further distance and try your transmitter from there. If you are noticing that your transmitter is not locking and/or unlocking, start the process over again to ensure that it works. If you have repeated the process numerous times with no success, contact your car care professional for further instruction/help. If the transmitter works at 20 feet but does not work at, say, 40 feet, the transmitter may not have a strong enough signal to travel that far, or that the transmitter's batteries are low.

Determine if your car has a VIC (Vehicle Identity Check). A common place to find this information is in your driver's manual which comes with the car. You can ask your car care professional. There should also be a button on your dashboard with a picture of a car, marked with the letter "I". If your car does not have a VIC, use the following steps.

Get in your car. Sit comfortably in the driver's seat, and make sure that your transmitter is close enough to the steering wheel and internal locks. Pull on the internal handles of each door to make sure that they are closed tightly.

Turn your key to the "Accessory Power" position. When you put the key into the ignition, do not turn it all the way clockwise. Instead, turn it to the position right before when the ignition would start.

Press and hold the odometer stem for three seconds. This is located in front of the driver's seat, behind the steering wheel. Do this until the display board reads "Relearn Remote Key." If your car does not do this, you may have your key in the wrong position. You can always pull your key out and start again.

Press and hold the Unlock/Lock buttons at the same time for fifteen seconds. You will hear a noise that sounds like a chime. This means that your transmitter has been successfully synced. If you do not hear this chime, that means that the sync is off. You will have to repeat the previous steps in order to successfully sync your transmitter.

Program additional transmitters, up to four. Do this in rapid succession, otherwise your car will go out of sync. If this happens, make sure that you begin the process over again, otherwise you will not successfully sync your transmitters.

Turn your key to the left and remove it. If you do not do this step right afterwards, it could throw the sync of the car off. If you forget to take the key out, or take it out a while afterwards, it is best to repeat the previous steps over again. Otherwise you could potentially have thrown off your transmitters, and not be able to work your Unlock/Lock buttons.

Test your transmitters. Step out of your car and shut the driver's door. Step about 20 feet away and press the Unlock/Lock buttons separately. If the locks seem to work, go back even further and test it again. If the locks do not appear to work, it is best to restart the process for your own safety. If you have tried and tried again, and nothing seems to work, contact your nearest car care professional.
