Turn ignition to on and horn beeps three times

alrights guy i hope this is the right place. I have searched this and found someone who had the same problem and the removed a fuse but it seems like theres gotta be a better solution. I have a 2012 tacoma prerunner and when i turn the key to on the horn beeps three times. Has anyone experienced this. It has a factory installed alarm on it from when i bought the truck new. Just started oit of nowhere one day. Really do t wanna take it to the dealer if i can take care of it myself. Everything seems to work fine. Also when setting the alarm i only get the alarm chirp and no horn

 

Bumb.. anyone heard of this?
