I dropped my car off to get the windows retinted finally. Was done around 5pm and the guy left my key fob under a towel next to the car for me to pick up after hours. Went to pick it up, grabbed the key, the door unlocked no problem with the key in my hand and started with the push button start. When I turned the car on my check engine light was suddenly on, wasn’t on before. Got home and checked the code: P0512. Searched around because I was baffled and found that someone had the same, they cleaned the rubber stoppers in the door jams and it worked for them. So I took the rubber stoppers off, cleaned them with rubbing alcohol, put them back on, cleared the code and restarted the car. Started up with no cel.

Fast forward to this morning (next day) and I go to get in my car and the doors aren’t unlocking. It’s early and I’m not thinking and go okay the battery is dead. Jump it with a portable battery, and I get in the car and to start it I have to start it with my key fob against the button. And even after starting it, the key light comes on the dash, so I realize then it’s my fob. Key light disappears and doesn’t show up again, but I can’t start my car without the fob against the button. Figure it’s the battery. Change the battery, doesn’t help. I also realized the red light blinked on the old battery anyway. Disconnected the battery terminal in a last ditch effort, no avail.

Really at a loss, I’m sure I’m just not connecting the pieces but what’s happening. Using my spare fob with a new battery, I have the same issue. Just so confused why the fob worked fine yesterday but now suddenly doesn’t.
