Does a 2003 silverado key have a chip?

Yes, a 2003 Chevrolet Silverado key typically has a transponder chip embedded in it. This chip is part of the vehicle's anti-theft system, allowing the engine to start only when the correct key is used. If you have a non-chipped key, the vehicle will not start, as it won't recognize the key's signal. Always consult your owner's manual or a professional locksmith for specific information about your key.
