Key remote not working,battery is good for lexus ls 400

ANGELOLISA.
JUST ONE DOOR FAILS.
WELL ALL FAIL FOR :
1: FUSE BLOWN
2; WIRES BAD
3 ;WINDOW GUIDE JAMMED up.
4: WINDOW MOTOR BAD OR ITS CHILD PROOFING CLUTCH BAD. (SAME REALLY)
5:CONTROLS BAD. AT DOOR.

A TECH DOES TESTS NOT JUST GUESS WILD.
USING A METER, CALLED A VOLT METER.
we check full 12vdc to the motor ,pushing up.
if good that is motor silent or sounds overloaded
it is or window is jammed.
so the tech pulls the motor driver and moves the window by hand oops its jammed. bad guides

for right now you must disconnect the positive from the battery. After you must call to the locksmith for a new key. see the diagram attached.

lexus 300 to open the button but i can not open still not working how i find the wire

lock cylender or ignition switch

CHECK THE IGNITION SWITCH FUSE.IF IT LOOK OKAY.I AM LOOKING AT THE IGNITION SWITCH.IT COULD BE OPEN.ITS NOT SENDING POWER TO STARTER.

Usually not. Disconnect negative battery terminal, then positive. Next remove battery hold down (type is specific to car model). Battery then lifts out and replace with correct new one. Install is reverse.

check the fuse's under the hood and in the car.

you have to have a main key. you may be able to remove the panel and release that way. under dash. pull cable.

I think, for this problem you have to go to the dealer. There is a few things that they have to do @ the same time. Also, make sure that you bring all of your keys to make sure that they all work with the transponder,good luck...matty

Make sure you have inserted battery correctly in key. If it doesn't work on one side, flip it on the other. Should work..
