Key Programming

Getting a spare key and don't yet have a service manual. Does anyone know the programming sequence (or must you have a dealer tool)? Thanks...Matt

I bought a new transmitter and got a new blade cut by GM and programmed the key myself. The transmitter and blade work fine.

One problem is that the key will turn in the ignition in only one position and not the other even though it's a double sided key. My other two keys work in both positions.

I called the dealership and they said they will have to take a look at it and try it. I programmed the key myself so I don't want to get charged service for a defective key I got.

It sounds like a defective key to me. I had my replacement key cut by the dealer, but I also programmed it myself and it works both ways in the ignition. If it is defective then shouldn't charge you for that I wouldn't think but you never know with a dealership.
