There are a number of things that can cause this, but I would suggest starting with checking for codes.
More than likely if we have a key issue or something else in the system, we will have codes but if not, then more than likely we have a key issue.
At this point, the best thing to do is perform the reset process so I am attaching the process below. If this fails, then we will need to replace the key and retest.
Please let us know what questions you have, and we can go from there. Thanks
