I used to have all of the codes that the dealer has. It was a sheet of all Toyota radio codes. I found it on a Supra forum after I locked myself out of my Supra radio. I'm pretty sure it covered all codes through 98 so you might want to get on the Supraforums.com and see if you can find it.
Hi I am in the same boat to ! I have a 93 and the radio and tape working, but the CD is not working and I am wonder if this problem have to do with the security code? I have more the 7 months with out my Cd's !
This thread worked perfect for my 92. The way to enter the 3 digit code is to hit the Tune up arrow right next to the one and hold it down then hit the 1 at the same time. This will make a --- up and down arrow display. Enter a 3 digit code like it says above and then hold down Scan, this will produce the first error, do this 10 times and now its in HELP mode. Now you can start the above procedure.
Very timely. I am planning on changing my battery and I don't have the code for my LX450 so I called the dealer in Reno, NV last week and asked them to check my VIN# and find my code. The answer they gave me was: "Lexus doesn't use security codes on their radios. I thought it sounded wrong...Thanks for the information.
