it may be as simple as a low FOB battery or as complicated as an antenna problem with the perimeter entry ..you dont have anything new on your keyring do you? a lot of things can interfere with the signals....To start, I would replace the FOB battery then if it persists I would take it in and get a more complete diagnosisWeird... now all of a sudden the trunk lock/unlock button for the doors works only sometimes. Then also was standing right by door and they didn’t unlock - I had to use the fab. Any suggestions?
Yup. I got the same message when my fob battery was going tits up.If you're not getting the usual cel/stop/start unavailability messages, then I reckon it's the fob battery on it's way out.
If I recall, I did get a warning on the dash. Told me the car couldn't recognise the key I think. Replaced fob battery and all was well again.
If you're 18 does have the original car and fob battery, they are both likely to go any time soon...
Not sure if it's the fob battery, as OP said he needed to use the fob to unlock the door.My guess is the fob battery.
