your door switches are probably dirty spray them with wd40 then scrub them with a tooth brush

in the door jam you should find the button for the buzzer some of these are adjustable the button might not be getting push in all the way if this doesnt fix the problem I would find that stupid buzzer and rip it out

We are having the same problem and looking for a solution. My husband is in the garage right this minute pulling things apart :0). Tried searching YouTube, but no luck. HELP!

Adjust the sensitivity of the alarm system.

It may be too sensitive and is being set off by the glass breaking sensors.
loud noises usually set this off if it is too sensative.

The warning chime is on because the GEM - generic electronic module think's the door is open . Your best bet ,have a qualified repair shop check it out . Unless you have a scanner that will talk with the GEM & the engine computer & ABS computer , checking DTC'S - dfiagnostic trouble codes . If you don't know about this , take it to a repair shop.

It's going to have to be looked at. But you can try unlocking a different door with the key. Hold it to the left (unlock position) for 2 or three seconds. Should shut off the alarm and allow you to start it.

you must go to dealer and have akey made because the one you lost probably has a theft deterant by pass built into key thats why it wont start you have a computer chip in your original key that by passed alalrm and it would start ur car they will need ur vin number

Most likely it is a switch on the van. Check the hood switch near the battery . The rubber cover comes off and causes the switch to set the alarm. Good luck.

Have you checked the owners manual for possible causes of the alarm?
