2004 Buick Security System

[regalman2004]

I recently bought a 2004 Buick Regal from a private owner. I noticed the security light was staying on solid, even when driving the car. I recalled that he said he had to replace the ignition lock cylinder. He Bought the part from a local parts store, which does not have a resistor on the key. With these two keys he also gave me 2 fobs which are programmed to the car.

Would there be any risk of the car shutting off because of this and can I take the new key to a locksmith to make a new key with a resistor on it, and would the new cylinder recognize the resister on the key? Any information would be valuable, since my previous cars were older models and had no security system. Thank you

Your vehicle requires a chipped/resistor key so you will need to check if the cylinder and key you were given is correct. Look up the part number to determine that, assuming it's still in the original box.

I read my question again. I meant to say he had already replaced the cylinder . He has already changed out the cylinder. The box has been thrown away. Checked several auto parts websites…none of the cylinder locks they have listed have resistors. I’m confused

Has anybody tried programming the key?

I did some research. I traced the cylinder and key from an auto parts store. They keys were blanks that needed to be made with the right resistor in it. The manufacturer stated the blank keys will not start the car. Well they do.

I asked a mechanic about this and he said that the dealership that installed the cylinder would have to had bypass the security system but using a resistor connected between two ignition wires.

I’m still scratching my head on this one because it has been two years since the cylinder has been changed…started by a key without a resistor and the security light is still on solid.
