Anti-theft switched off my starter...how do bypass that issue?


Depending what part of the country this car was purchased originally, the alarm system can be different. These are after market systems installed by the distributor or dealership. Different systems are connected differently. Either way the alarm system is connected to the engine controller and or the main electrical circuit. This has to be removed and the circuit reconnected. I would advise taking to a car alarm specialist and have them replace or remove it.

I HAVE A1992 LS400 LEXUS THE ALARM WAS GOING OFF AND THE CAR WOULDNT START,WHAT CAN I DO




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

Okay you may want to check to see if the sensor on door lock cylinder hasn't fallen off from the lock itself. Pull of the door panels and check the wires at the door lock cylinder. Hope this helps.

My Lexus LS400 was running perfect - no issues whatsoever. Today it won't start. Have tried jumping it but no luck. It acts like it is about to start but won't.


sounds like an engine immobilizer problem. close all doors,hood & trunk completely. lock and unlock the car three times with remote, then put key in door lock and lock & unlock three times.
did you accidently try to start with wrong key?

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.
