My '99 does not telescope at all so I need to do the fix but interestingly enough, the tilt started not lowering intermittantly and then stopped altogether. I can lower it manually and it always raised automatically when the car was shut off. The telescope does not function manually. I had a spare key so I tried that and the wheel lowered when placed in the ignition consistently so I'm thinking it is the micro switch that needs cleaning although I don't know why the key would make a difference?

Sure thing...I'll get a photo and post what I know about how the shop did the installation.

On my recently purchased '99 LS I removed the engine cover so I could check the condition of the plugs, etc. On top of the engine there was a small plastic box that said DIAGNOSTICS. This same setup was on my '90 LS but I was surprised to see it on my '99. There didn't appear to be any connections inside the small grid in the box so I'm wondering if this is just a leftover thingy or what?

OK, so my face is red. I was actually able to find some instructions that worked so I programmed my key and it will start the car. There is a separate set of instructions to program the remote and I'll tackle that later. At least I have a spare key that will get me into the car, manually, and start it. I was so stunned that the key worked that at first I didn't believe it.

OK, here's a pic of the SiriusXm radio installation I had done this weekend. very clean and no wires anywhere except in the former ashtray locations. The cigarette lighter is still active for a GPS or whatever. there is a rocker switch under the dash between the console and the steering column. Works great!

I didn''t know that the aftermarket keys were incompatible. If they are, I would think that the sellers would be guilty of fraud for selling them. I went on the net and have found, so far, four different sets of instructions so I am guessing this is not an exact science. So would I be fair in saying that the money I spent on the key and cutting is down the drain and that the only way to get a programmed key is by going to the dealer? If that's true then I'll just have to suck it up. It also may explain why I have never been able to program a key for my wife's Miata. Wondering how the Ebay sellers get away with selling incompatible keys and why ebay doesn't crack down on them? Oh well, thanks much for the info as always.

JUst got '99 LS with one master key so got another transponder key online and it came with instruction. Had the key cut and tried the instructions that came with the key. No luck. Tried the PDF instructions attached earlier in this thread and they are totally different from the instruction I got with the key. So now I'm really confused. In the PDF instructions, Section A, 2 and 3, are these steps done from inside the car or outside the car? In section B, I assume this part is done with the unprogrammed key but it doesn't say that anywhere. Has anyone, other than a Lexus technician ever programmed a key successfully? I think Lexus not only gives out bad instructions but also pays the online key sellers to send bad instructions so you have to go to Lexus and pay the money. But then, maybe that's just me and my frustration talking. Thanks for any help and if you have programmed a key successfully, you are my idol!

Thanks for the info and the pic. I have a Garmin that I am going to use and mount somewhere. I love the garmins but like the look of the in dash unit.

I have a stock '99 LS400 with a Nakamichi radio and without navigation. Was wondering if I can put a factory unit in and is it just a plug and play or are there wiring issues? Thanks for any iinfo.

My email is ujoint56@yahoo.com Thanks

thanks for that info, I'll check it out.

Thnaks so much for that reply...I now have a direction to go in.

My wife wants me to install SiriusXm radio in our LS and was curious if anyone has found a way to do this? Can the antenna be installed inside and not on the ourside of the car? Sorry if this has been discussed before. I am a new member and haven't learned the ins and outs of the search function.

thanks for that...now I have an idea of where to look for the mountings.

Revisiting this because I still need to change the bulbs in my 99 ls400 and I can't find any info on how to change out the bulbs without removing the battery etc. I removed a couple of bolts but the headlight assembly will not budge. Thanks for any help.
