HOW DO I MANUALLY DISABLE THE ALARM FOR A 99 DODGE INTREPID

SOURCE: Have a 2000 VW Beetle. The alarm won't turn off!

My 2000 Beetle does same thing (although not all the time). Just found an internet post that suggests there is a problem in the door lock sensor. I assume you are using a regular key - not
the keyless entry - like I am. He also said that you can disable the alarm (also disables the
keyless entry - which doesn't bother me) by leaving the front door AND the rear trunk open and
starting the car up. Seems to work so far. I will get the door lock sensor replaced and turn the
alarm system back on (not sure how yet), and let you know if that stops the problem.

you need to reset alarm/immobiliser.lock car with remote, hold button down for 30 secs,then press/hold down unlock button,should reset.another way is with key in ignition/turned on, press alarm button down and hold for 30 secs.this resets immobiliser.toyota
systems vary..depending on market.
