The horn when pushing the steering wheel button and keyless entry are separate horns. Main Horn is behind the grill (steering wheel horn). Keyless entry Horn is located by coolant reservoir side. Check your horn fuse. If good. Then check the 1 positive signal wire going into the horn behind the grill using a test light and having someone push the horn for you. If it has postive signal. Then horn might be bad or isnt getting proper ground.
