2 keys programmed

Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.

I’m having this problem with my car What ended up being wrong with yours? I have A 2010 Buick LaCrosse and it says 2 keys programmed, the check engine light is on, and it won’t start? Any suggestions

I had the same problem in my 2010 lacrosse cxl, also did not raise or lower the windows, rear defroster didn’t works and other weird things, also I felt heavy start up. I went to auto parts shop and they ran a battery check, it turns out that it had a broken battery cell and had to be changed, I put a new battery and magically that solved all the problems, apparently when there are battery problems, the car disconnects some unnecessary systems that lead Also I didn’t get again the fob key message.
