I have an '01 RX300 and just discovered that the master key won't work. I put a fresh battery in and the remote operates the locks but won't start the car. Dealer mechanic told me it's very unusual for the chip to go bad so I'm going to be out $200 for a new key. Have one master that works fine but want to have a spare. Anyone else had this trouble?

Thanks

I had the same problem with my windows this summer; wouldn't close, wouldn't open, would bounce back and forth. Took it to my mechanic and he told me the master switch was bad and while it's about $70 in most cars, the one Lexus uses has a mini computer in it and it cost $700. Few days later I learned my "sprained" ankle was actually broken and when I got home that day, didn't close the door tight, so the light stayed on several days (I was stuck in the house on crutches and couldn't drive) until the battery died. Once I was able to jump start the battery, it was like rebooting that master switch computer and it's been fine since.

Dear members,

I found that my passenger side power-window was acting strange. Both the driver master switch nor the passenger switch could have a very hard time to move the window up. Lubricating the window track had been tried but it didn't work.

Finally I replaced the window motor. Now the window can move up and down okay. BUT once it hits the top w/ automatic open, it just bounces back down to the middle and leaves it halfway open. Then I have to manually click up the switch until it closes all the way up.

Am I missing something here!? Some relay is also broken? Where? Or the window motor needs some special reset procedure? I have only tried holding the button down - wait 1 sec - and up to the top for 10 sec AFTER disconnecting the battery.

Anything else? Please help from all the experienced members.

Thank you so much!

2001 RX300

One of my master keys no longer works. The remote locks and unlocks the doors but the car will not start. The key fob battery is new and dealer service rep said it's very unusual for the chip in the key to go bad; with my other key, no problem.

Anyone else had this trouble?

I just took the cover off at the passenger feet,, under that is the temp control motor and valve,,, I turned the temp from cold to hot and the motor and valve are working just like they should, moving nicely. I wanted to make sure that the heater core was not blocked,, so I disconnected it and ran water thruogh it,, no problems totally open.

Is there another motor or valve that would have anything to do with this?

Any Help?

I brought my '01 RX300 to the dealer today for no heat. Told the servo was bad; part of the AC system that controls air flow. They have to order it so my Lexy is in the shop until Tuesday but at least I have a brand new ES loaner. Car has 100,000+ on it so have to expect stuff to go bad.
