Question about 2001 Toyota Avalon

1 Answer

Is it possible to disable the security key system on Toyota Avalon 2001? My car does not start sometimes and I have the shop run the test but could not find any problem. They think probably I don't have the master key (look like a copy). Instead of getting to a dealer, could I try to disable the need to use the security? Is it an option? Another word, can I bypass the security for starting the car?

How to disable the vats security system on my 2001 oldsmobile alero?


you cant disable it, its a pass key system not a vats system (vats reads a resistance value in the key). The ignition cylinder has a sensor in it that measures a rotating resistance (then translates into a voltage reading) that the bcm reads to let the car know to start. Usually you can try and start the car, then the security light will start flashing - leave the key in the on position for ten minutes until the security light goes out. Then turn the key off, wait, then try and restart - they usually relearn the code after the first 10 minute try. Sometimes it takes three 10 minute cycles.

Car starting problem, but if I connected a wire from the starter to the battery it starts fine. Is there a security system in between the starter and battery that I can disable? Is it the security or...


I believe what you are looking at would be the starter solenoid. For the cost, you may want to replace the starter with the solenoid - depending upon the vehicle.You really should inquire on that.

1997 toyota avalon will not crank or start horn blowing and lights flashing security light on.


Try unhooking your battery for about ten mins. This might reset your security system. You might also try locking all the doors and then unlocking with the key.

If the keys have a chip, you may have to go back to the wrecker and get the computer out of the same car. Not sure about your car, but thats the way the older gm products are. If there is no chip on the key... i'm out. Sorry.

1998 toyota Avalon, the car alarm is going off when opening the drivers door manually with the key (remote is broke) and then the car will not start.


Same here... I have a 1998 Toyota Avalon XL. My car battery died. Replaced my car battery, but found out that when you unplug and plug the car battery with this car it engages in security mode (I have factory car alarm). This disables the engine and wont let you turn the ignition aka start the car engine until the remote (keyless entry) "UNLOCK" is applied. My remote is also lost so I cannot disable the alarm.
The only thing I can think of to do is unplug the battery again to disable everything (car alarms are annoying...) and call the dealer to pick the car up and perform the diagnosis. Most likely they will offer you another keyless (ugh... expensive) and/or you could ask to disable the factory car alarm.
I know thats not much help but it seems to be the only option from what I researched currently....

2001 Toyota Avalon quits when at idle


Just had the same problem on the 2002 Avalon. Pulled the throttle body off and removed and cleaned the Idle mixture control valve which was caked in deposits. Runs like new now. About 2 hours of work or less. Common problem with this model I heard. Hope this helps. Some one gave me this info over a year ago and I finally got around to doing it.
