I purchased a 2004 Trailblazer EXT for my wife. Keyless Entry Works perfectly. My question is: Is there a way to program the horn on the keyless entry? I looked in the owners manual but my vehicle does not have a customize button on the steering wheel. My keyless entry works but no horn sounds. Is there another way to program it to sound when the keyless entry is used? Any help is appreciated!

There is a method - it's somewhere in the owner's manual. It involves holding certain buttons and pressing others. Look for remote entry confirmation/verification in the manual. Or also programming power door locks.

I found the instructions in the owners manual but it says to push the customize button on the steering wheel. Unfortunately my Trailblazer has no buttons on the steering wheel. Any other ideas?
