Top 20 1997 Lexus LS 400 Questions & Answers

Question edited for clarity, full 'year MAKE model'. Question moved to Year Model category. You can't! You have to fix the problem not find a way around it. You have a Lexus not an 1981 Chrysler. I have an ES330. Your antitheft system is protecting your vehicle to stop precisely what you are trying to do, drive the car without the correct credentials. You have a transponder chip in the key, a receiver in the steering column, alarm sensors, the antitheft module, the Body Control Module, the Engine Control Module, and all the break-in sensors on hood, trunk, doors, and inside the vehicle all protecting you against theft. You need an auto electrician, the dealership, or an auto locksmith / alarm installer with a pro grade scan tool computer to check the system and find out why it isn't working. If you lost all three keys, the dealership can make a key based on the VIN Number. Get one and then get the auto locksmith to make another and program both. https://www.google.com/search?q=auto+electrician+near+me

Test battery with load tester. Check for electrical short.

is it connected properly? if so check your fuses and see what is blown.

Forgot a wire that hooks to either ground or positive terminals. might have dropped out of site while swapping out batteries.

Other than getting a locksmith, you may have to remove the door panel and take the lock out from the inside. Then replace it or remove the broken key. Hope this helps.

There could be a number of things wrong. It could be your battery is dead. or the starter has gone bad. or the ignition electric box which the key moves could be bad. It is kind of hard not being there.

It sounds like maybe your I.A.C. (Idle Air Controll) valve is stuck or gummed up. Try cleaning it and check for vaccume leaks.

A mechanic would use starting fluid to suppliment the fuel supply. Then check for fuel pressure with a gauge. It could be the pump relay among other things.

The short answer to you question is yes, eventually. The transmission fluid on the wires can harden the insulation on the wires which then cracks when the wires flex and at that point it can short out. The lights dimming and the wipers slowing are indications of a high power draw and add to that it gets worse when it's wet make it a lock that you have, probably, bad wires. Carefully inspect the full length of the wires. If you find cracked or worn insulation either repair the short if it is worn or replace the wiring harness if the insulation is at all cracked. Most likely it will be a major power line. Good luck.
