3 Honks when Unlocking Doors with Fob
I had to replace my fob. Both died, and I purchased a new one, had the dealer program it, and all was well for a time. The other night, my alarm started going off randomly. No one was around. Also noticed that when I unlock the door with the fob, I get 3 honks. If I hit the unlock with the doors unlocked, it acts normally. Lights flash etc.
Confirmed it is not the fob as I had removed the battery for a time, and the car still was randomly going off. Is there a common issue with 08 Cobalts and alarms/ keyless entry? I do not have remote start. The fob is an aftermarket, I did not purchase it from the dealer. Not sure if that matters.
