It might be the alarm system; or your car is going haywire.
When a car horn goes off while the car is switched off, it means the horn has a bad ground.
It may or may not.
no power to the relay, whats the point of a horn when the key is off?
Each beep means something different - One is a confirmation tone for decoding, one could be for bluetooth headset (if you have one) and the other can be a single beep which can randomly go off.
if u are in a car simply HONK THE HORN
Firstly, turn the ignition on but don't start the engine, then turn the headlights on, then off, then turn them back on, then off again. (so twice on, twice off) the car should beep at you twice indicating this function has been switched on. To switch off, repeat the same steps above and the car will only beep once.

It will sound an alarm through the receiver that goes beep beep beep.
The horn goes off by itself on a 1998 Malibu as part of the security system. When the security system is enabled, noises and people touching the car can make the horn go off on its own.
Clicking on your seatbelt will turn off the seat belt reminder beep.
The ignition turns the car's electrical system on or off, in addition to starting the engine.
You need to determine whether the horn button or the horn relay has failed using a voltage meter and replace the damaged part.
