How to make horn beep when locking doors

SOURCE: door lock 2004 jetta wagen

If remote locks and unlocks driver door but does not unlock passenger doors,then follow the advice above:
Get in the car using the key to unlock the doors. From the passenger side lock and unlock your doors using the button on the passenger door. Get out and the remote should now unlock all the doors with 2 presses.
Worked perfectly for me after several other suggestions (and dealer) failed.

Try replacing the battery in the key. It may be too weak to engage lock.

You might can have the dealer program it not to honk, but its just the way the keyless entry works. I've owned 2 accords--an 06 and 08--and both of them honk the horn when the lock button is pressed twice. Pressing the button once will secure the car and arm the alarm. So once click is all you really need. And no your alarm is not malfunctioning.

I have a similar issue on a 2001 Jetta sedan. jandkat seems to be talking about the old system that VW used (pre-1998). To my knowledge there is no vacuum-based locks in the 2001 models. I've had the door completely apart and there are defiantly not any vacuum hoses. The only 100% for sure fix I have found is to replace the door latch mechanism. There are some other options but I'm not sure they would completely fix the issues you are having. Now for the bad news: you can only get this door latch mechanism from VW dealers. I have yet to find a place online or elsewhere that carries them. They are around $185 for the latching mechanism and if you don't want to install it, be prepared to pay another $200 or so in labor. If you do want to do it yourself, here is a great site that has step-by-step how to take a VW door apart: http://forums.vwvortex.com/zerothread?id=1015107

Hope this helps

hold the lock and unlck buttons simutaneously on the fob until you hear the the horn beep.this should do it!you may have inadvertantly changed the modes by accindentally doing the same...kinda like **** dialing your cell phone! if this doesnt do it may have blown fuse or horn for security system may have failed.you did say doors lock but horn doesnt sound right?
