To know for certain if *your* Chevy truck has a chipped key, you should:
* Check your owner's manual: This is the most reliable source of information.
* Try the key in the ignition: If the truck only starts when the key is properly inserted and turned, it's likely to have a chip. If it starts with just any metal key of the correct shape, it's likely not chipped.
* Look at the key itself: Some chipped keys have a small visible marking or logo indicating the presence of a chip. However, many chips are embedded inside the key head and not visually apparent.
* Consult a locksmith or dealership: They can definitively tell you whether your key has a chip.
In short, there's no single answer. You need to identify your specific Chevy truck's year and model to determine if it utilizes a chipped key.
