Keyfob when locking no horn

My keyfob recently when pressing the lock button the horn used to beep 1 time and now it doesn't my horn does work if pressed and if I press the panic button it will go off...Anyone?

This should probably be in OEM tech... (unless it's an aftermarket alarm, I guess)

I think it's a config issue, I recall there being some way to change this setting by pushing and holding certain buttons. A little searching should find the answer, there was a thread about it in the last two weeks.

you hold the lock button for 5 secs and the press the unlock button once (while still holding the lock button), it should beep and that's it.

Scroll down the page and check the threads listed there.

This was covered recently, and the remote programming was posted in the thread.
