The horn blows once about every 20 minutes after I turn the car off and lock it.

There is an alarm module that controls the horn when the system has been activated it sounds like it is going bad. If you want to cut the wire to stop the horn here is a wiring diagrams to help you see which wire to cut.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.
