It's a 2006. The horn will beep 5 times quickly at random times. Why?

Also, every time I turn the car off and pull the key out, it will honk 2 times. Under the steering wheel there is a small black box. If I push and hold the button on it, it will turn a blue light on. When the light is on, the horn will only beep 1 times when I turn the engine off and remove the key. Any ideas?

 

An old alarm system? Did you buy it used?

 

I believe it's the factory one. Yes it's used.

Just honked again. Maybe it was 6 times. Haha

 

Have you checked the relay and fuse?

 

All that is missing is a loudspeaker saying "PROTECTED BY VIPER!!"
Anybody remember those alarms?!
