A friend changed out my coolant thermostat housing and had to take the battery completely out to get to it. As soon as it was reconnected an alarm I never knew I had started going off. I don't have a remote so my friend had to take the fuse out to my horn for now. The weird thing is I couldn't open the driver door when it was unlocked, I could get in the passengers side, and all the lights flash in my car along with the alarm. The engine turns on and I can drive but the lights will still flash every few minutes while I'm driving and it looks like my hazards are on. I have no clue how to make this stop if anyone can help. Idk if my car is trying to add another key to the system or if this is an actual factory or aftermarket alarm I wasn't aware of (purchased used).
