Symptom: The horn will randomly start beeping…
• Never blasts (longer duration), but rather always a quick beep

• The beeping doesn’t happen every time you drive, in fact, I may go several days without a sound

• However, anytime it does beep, it will beep frequently, but never in a pattern- always randomly

• The beeping seems to be independent of any normal causal factors (outside temperature, engine temperature, humidity, time of day, time of year, weather, car moving, car standing still, etc.)

• Moving or striking the steering wheel or column does not affect the beeping or non-beeping

• When it is beeping, the electric car lock/unlock does not work, and in fact, depressing the lock/unlock button will make the horn beep

• If it is beeping (and hence the lock/unlock is not operational), if you turn the ignition off, and restart (even immediately), it will “reset” and the beeping will have stopped and the lock/unlock will be operational again

Thoughts?

 

What kind of alarm does it have?

 

Factory standard alarm...

I suspected this early on, and removed the security alarm fuse, and the problem still continued.

Don't know if that helps...
