This morning my kids managed to set off the anti theft in my 99 Accord. I have no idea how they did it, but the horn just kept blaring over and over again. I was able to put the key in and start the car, even drive it out of my driveway, but the horn would not stop! Ugh!!! I bought the car from my brother so of course there was no key fob to be found, and all I have is a single ignition key.

On the off chance this happens again, what can I do to kill the horn??? My husband tinkered with it and he has no idea what he did, but it will now start without the horn going and it's driveable again.

Thanks!!

 

Is it a factory or aftermarket anti-theft system?

 

It's factory. I just lock and unlock the old fashioned way, not by fob

 

Buy a fob from the dealer.

 

well that's what I was hoping to avoid doing

 

They aren't THAT expensive. Plus, they are convenient.
