Hokay, my key/fob works but the key does not come out when button is pushed. Bought an empty case with a blank key. Is there a thread somewhere (search got here) that says how to open the two cases and swap the innards ? YWTK.

 

This is the thread you want to follow in order to not damage anything. There is also a few YouTube videos out there but this should help. Just ask if any questions.

Thank you, just what I need.
