My car battery died after charging the battery the
alarm went off. I disconnected the battery again and
reconnected. Now it is making a chirping sound
Lock and unlock the car, open the door. Get in and insert the key and turn it off and on 4 times then start. If that doesnt work, replace the battery inside the fob and repeat. If that doesn't work, and its factory alarm, see a dealer for reset. If its aftermarket alarm, good luck.
