Many 1994 models did. Cutlass Supreme 88 88 Royal LSS 98 Regency
No, it doesn't. It uses a "passlock" system. The resistor, or "chip" is part of the ignition lock cylinder. The chip in the key is called "passkey", where there is a resistor in the key, which is quite visible.
It could. A gray key does have a chip, a black key does not.
If the key is gray, yes. If the key is black, no.
Grey key, yes. Black key, no.
the security chip in the key might be bad or missing
In 1999 it may or may not have one. If it has a thick black head with the hole in the head of the key being offset, then it is probably a chip key. If the hole is in the center top of the key or completely metal then it is not a chip key.
If the key head is gray, yes. If the key head is black, no.
If the key is gray or has built in buttons, yes. If black with no buttons, no.
Some do. If your factory key is just flat metal you don't have but, if there is a little (usually black) square chip on it, you do. Most with a key fob do as well.
yes,im not sure if model matters but the chip is in the rubber part of the key,there should be a black and a grey key(valet key) for the 1999 and up models.dont set your keys on any magnets
it depend where you go to get it done, where you live, and if the key has a micro chip in it or not. when you look at your key right below the base if there is a little black piece of plastic then there is no way to get the key copied (the piece of plastic is a micro chip)
If your key has the anti-theft chip on it, the best (and likely only) place would be a Chevrolet dealer.
