Re: Key issue
Mine started to show this message when the battery started getting low in the remote. I replaced the battery and it works great now. I could still unlock the doors automatically just it wouldn't let me start it every so often till the battery was changed out. Just what fixed my issue. Hopefully you're problem is just as eaasy to fix.
