if it has an alarm hook up the cables so the alarm goes off then deactivate it with the remote. if you dont have the remote then you need to take it to an alarm shop and get a remote programmed for it if they cant they will have to remove the alarm and you will need to get an aftermarket alarm for it but yea it wont start because the alarm was on. when you try to jump a car with an alarm even if you have the keys in the ignition the alarm will go off its a fail safe so noone can jump your car to hotwire it. but just do as i said jump it and disactivate the alarm with remote and it should turn over with ignition......
one thing you can try close all the doors lock the doors.....USE YOUR KEY TO LOCK THE DRIVERS SIDE DOOR AND THEN UNLOCK IT. See if this might reset it.....
Best of luck i hope this will help

    This happened to me. I was able to reset the alarm by locking the doors manually (except drivers door), then using the key to lock and unlock the drivers door. The car started after that. Thanks for the tip!!!

Can i use dextron 2 transmission fluid in a1992 lexus ls400
Hello there,

Surely, you can use a Dexron II transmission fluid but I would recommend you get the Dexron III instead. In actual fact, always use Dexron III ATF for better efficiency of your vehicle.

Best of luck....

My 1991 Lexus LS 400 does something similar. When the alarm goes off I use the key to unlock the passenger side front door and it turns the alarm off. Go figure, I know it sounds funny but it solves the problem for me.
