I have a 99 GAGT, that is new to me. It has some very odd issues.

The first that I noticed was that the doors lock and unlock randomly, while driving. Not really all that big of a deal for me, so I have not worried much about it, but I would like to fix it.

The second has started happening recently, but did not happen before, that is when I start the car, the horn will give several very short honks, then go into a full honk repetition, like an alarm is going off.

Does anyone know what might be causing either of these issues? I've tried searching, but maybe I'm just not using the right terms, because, I am not finding much.

Check the battery connection, mine did that when the cable was loose, the security system thinks that someone is trying to hotwire it.

do you have a aftermarket alarm or remote start?
