Q: Warning Key System
I have a 2011 Infiniti M37x. "Warning Key System" I changed the battery and the warning still showing up.
My car has 86000 miles.
My car has an automatic transmission.
If you have the extra key then try it to see if problem is with the key or the key warning is a theft system issue? You may need to have system reprogrammed by a locksmith or dealer.
