How do you disable the alarm on a 1999 Toyota Avalon when you don't have the keyless entry and must use the key to open the door?

i had the same problem...when it would lock me out i disconnected the cables to the battery and it would unlock the door.

no mechanics was willing to do it because of not knowing which cable was which, many recommended that a stereo installer or Toyota dealer, but i finally found a mechanic who had worked for Toyota and easily and quickly removed it.

another idea if you are car savy is to contact the alarm company asking for the instructions.

I have a different answer than the person above. If you've lost your keyless entry and the alarm gets tripped, try the following steps (I know it works in slightly older Avalon models): First, disconnect your positive battery node. then open the passenger side door and leave it open. Next, put the key in the ignition and turn it to the on position (also if your car has a red button next to the steering wheel on the dashboard push it in). Reconnect the positive battery node and get into the car, leaving the drivers side door open (if the red led light has popped back out, push it back in). You should be able to start the car and the alarm should be disabled. Sometimes it takes and second run through of these steps before it works. Good Luck!
