This may be a Body Control Module (AKA, BCM) issue, this module controls these functions, wsaw this same issue on a Buick, it was the BCM, you will have to have an active system tester with live data stream cycle the locks to see what the problem is, as far as I know the dealer is the only place that has this type of dedicated test gear.

Put new battery in car and horn continues to blow


Hi Guest,
If the horn is blowing in pulses,it is probably the anti-theft system. Connect the battery and either lock and unlock the doors with the remote or use the key to lock and unlock the drivers door. This should force it to reset. If this does not work,drop me a line and we can go further. Good luck,Chuck

I need to reset my car alarm on my 02 vw golf. the battery has been replaced so alarm wont unlock doors


stick key in driver door lock and unlock it. If that works, now see if the remote will unlock the door or doors..i remember reading in an owners manual once where you can program which doors open and close by they way you press and hold down the two main buttons, also after a battery change in the remote, i think, but not sure, i did this on a blazar i once owned... the owners manual said, that you had to be within 20 feet and press and hold down both buttons till it makes the arming sound.... Can i get some feedback cause im curious..thanks.
