Hi,

If the key tumbler has been replaced and you are unable to use the old keys, the (PATS) passive anti-theft system needs to be programmed to accept/recognize the new key. This requires a scan tool that can communicate with the PATS system.

I attached the directions below. Most people don't have the tooling to do it. If that is the case, you may need to contact a locksmith or a shop with the equipment needed.

I wish I had a better answer, but that is what is required.

See the directions below and please feel free to ask questions.

Take care,

Joe
