key reprogram?

More then likely this is not a key programming issue unless you are trying to use a key that has not been programmed. Otherwise there is an issue with the system which means we need to follow this testing in order to figure it out.

Here is a guide that will help with this type of testing:

This means we need to run through this testing and find out what the issue is. Also, you could try another key if you have one, just to eliminate a faulty key. Otherwise we need to complete the testing to find out what the issue is.

Let us know if you have questions. Thanks
