Keyless entry is a feature on many Chevrolet models. Through the use of a "clicker," often referred to as a fob or remote, you can lock and unlock your car before reaching it. Some cars also feature auto start or an alarm system. It's important to remember that a key fob can control only those features already installed in your Chevy; purchasing a remote with auto start will not work on a car without that system installed in the car's computer.
Key fobs for your Chevy usually feature at least two buttons. The lock and unlock buttons will feature pictures of a closed and opened padlock. If your car has an alarm, that button is sometimes red and has an image of a megaphone or trumpet. Other possible features include trunk entry and remote start, which is a circular arrow. If your keyless entry isn't working, you may just be too far from your car. The range varies from remote to remote, and that range will decrease with the battery life. Bear in mind, particularly in parking garages, that the signal goes vertically as well, so avoid using the unlock feature until you are walking toward your visible car. If the remote fails even right next to the car door, you may need to clean the battery with a soft cloth, or purchase a new battery or key fob. Like any other remote, it should never be exposed to extreme temperatures or water. If replacing the remote does not fix your problem, (or it works on only some doors) take the car to a technician. In some cases a wiring problem can prevent the locking system from functioning correctly.
If you need a new remote for your car, you should be able to find it at a Chevrolet dealership. There are also many websites that offer remotes by model, make and year. It's important to find a compatible remote; a forgotten remote for a Saturn cannot be programmed to work on a Chevy. A used remote should work just as well as a new remote and they can be found for $30 or less as of 2010.
To program a new remote, first sit in your car with all doors closed and locked. Insert the key into the ignition but do not turn. Hold down the unlock button on the driver's side door while quickly toggling the ignition on -- off -- on -- off. (Do not actually start the engine, just turn the key far enough that the lights come on.) Release the unlock button after you have turned the vehicle off and wait for the doors to automatically lock and unlock. Next, using the remote control you need to program, hold down the lock and unlock buttons at the same time. Wait for the doors to automatically lock and unlock a second time; this could take as long as 30 seconds. Repeat for any other fobs needed. The last step is important: Turn the transmission to the on position once more to end the programming sequence and complete the process.
