My 2002 Set For Awhile I Had To Replace Battery Now Horn Blows When 1995 2004 Toyota Tacoma

Chosen Solution

My 2002 set for awhile I had to replace the battery now every time I try to start the truck the horn blows like the alarm is set off, why?

Try resetting the alarm by rolling down the driver side window, locking the door with the inside switch and shutting the door then unlock the door with the key fob!
