There is nothing you can do to fix this at home, you need the dealer to scan the systems module and see what is going on.

Most likely the door lock actuators. Its unusual for two to go bad at the same time but also not unheard of.

Thanks for using FixYa. First of all you’ll need to check battery voltage, recharge it if it is low or jump start with another battery charger. Inspect, clean and tight both ends of all battery cables. Also check, clean and tight wiring connections. Check for voltage at relay. If relay has voltage but there is no "click" when key is turned to start, replace relay. Remove starter and inspect drive gear and flywheel teeth, replace damaged parts if necessary. Check to see if voltage reaches starter relay/solenoid when turn to start. If not, check for open P/N switch and brake or clutch pedal switch. Please pry the interior panel and release the inside door locks. If still the issue is not resolved then you’ll need to drill a two inch hole into the latch to access the inside lock link through the interior panel. After removing the panel replaces the latch to resolve the issue. See the picture where to drill---

Please do accept the solution if the issue is resolved or else revert for further assistance.

SOURCE: 1990 lexus ls 400 security system went off now

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.

Well it looks like car had a after market alarm installed. If so, The siren has been removed. But the alarm brain box remains powered up under dash. You have to find it and remove it. And there is a relay that is a part of the alarm system. It basically interrupts the starter circuit. Just remove it and splice the 10g wire back together the way it came from factory. That's it. Car should start no problem.

As far as windows that probably is separate.

The hood is also seperate issue I believe.

I have a 1992 Lexus ES300 that wont start. I think the heads are blown. Can I just replace the heads or do I need a whole new motor? It overheated and the radiator hose busted and it hasnt started since....

Yes, you could replace just the heads, bu i don't think they are the problem - it's much more likely that the head gaskets have failed , they are the ones that you should replace first.

Sounds like a problem I had with my 2000 ES300. Cleaning out the IACV (idle air control valves?) took care of it, at least so far.
