Well I'm looking for possible soultuions before I try it . I recently had to put a battery in my 2002 toyota rav4 and my alarm goes off everytime I open the door ...... goes off for 30 secs or so and that's it . How do I disconnect the alarm ??? Can I disconnect at the flashing red light button ???

Sorry you can't disconnect it. you should be able to reprogram it though. look in your owners manual. most are programmed threw the radio controls.

Battery cables are totally clean?
hen try this
Use the key to manually unlock the driver's side door. This temporarily deactivates the alarm, giving you access to the inside of the suv.Place the key in the ignition and turn it forward one notch so that the battery activates, but the car isn't running. Look for the alarm box under the dashboard. Some models have an override button that's either black or red. Other models have a toggle switch on the box to override the alarm. Press and hold the override button in until you hear the alarm chirp once, signaling the alarm is disabled. If you have a toggle, flip it in the opposite direction
