I assume you have no keys already programmed. if that is the case, then you need to follow this process attached. If you have one or more keys already programmed, and you need another key, then you need to follow the "spare key" process.

If you have no keys programmed currently, make sure you follow each step (use a timer) or it won't work.

Let me know how you make out. Thanks
