replacement keys
Hello. I recently lost my only set of keys to my 06 GX470 and now all I have is the valet key. Can i get a new buttoned key made through lexus dealership without the master key? How much is this typically and also is there a less expensive way to get new key made. any help would be great. thanks.

You need a key with a chip in it to make a duplicate without reflashing the ECU. Do you have the little wallet key with the chip? Mine was in the leather owners manual pouch in the glove box. That will work.

Related issue here. We have only one set of keys to my '03. I'd like to have a second set made now that we seem to have misplaced the valet key. Any recommendations on how to go about that, approx price, etc? I know that this isn't going to be cheap, which is why I've been procrastinating doing it.

Then take the key somewhere to get it programmed or buy a techstream and program it yourself.
New key arrived today (2 day delivery again). It is OEM and it was cut perfectly. I didn't mess with programming. Took it to ACE Hardware and had them do the programming. Works Great!
Programming was $79.11 with the tax. A little steep, but my closest Lexus dealer is 40 miles away. Figuring in gas, time and tolls, not tooo bad a deal. Total cost was $187.27

I've got a Techstream but no compatible computer to use the software!
I was under the impression that ALL the key functions could be programed via the computer. Maybe the dealer can do it that way.

Confused,
I used techstream without flashing the ECU, I erased all of the keys except the one in the ignition and programmed other 2 keys. Total of 3 keys.
I did this, in case previous owner had a key.
I did this few times, there is a an option for it without flashing ECU.
I used Techstream with Windows 7 and 64bit machine and posted instructions on this board. You dont need XP and 32 bit.

Techstream told me there were no more keys available! All were used. When I bought the GX, no master was available so they had one made. I do not know how many were made with the original owner. Somewher along the way 5 keys were burned. I just need to be darn careful with the one master I have, I also have the wallet key and chip and valet key.Wife will have to use my key and won't have her own.

When I first connected with Techstream it said I have 4 keys in the system or 1 left. something along those line.
However, I only had 1 key on hand.
I bought 2 keys and erased and programmed to open the doors and START.
Please see this video and pay attention at 2:46 time

Thanks GX, I should have looked for some tutorials before I tried to fly by seat of my pants. So this process will not harm the key in the ignition and the wallet key and valet key will be fine also? It just erases all the other smart keys in the system?

It will erase ALL keys except the one in ignition. It will not harm the key in ignition.
You have to reprogram wallet key and other keys.
When you program wallet keys make sure the chip part is connected to the metal ring around the keyhole AND within specified time, you have to be quick.
Just remember to be fast when programming key and have them in front of you. You will get it. I kept getting timed out first few times.
The first time I did this I was scared also, and when I keep getting timed out when programming, I was getting worried, and to top all of this, wallet key (2 parts chip and key) chip part has to be touching the ring where the key goes AND you have to use the wallet key to turn the ignition when programming. the trick is to once hand touches the key cylinder ring with the chip and another hand turning the key cylinder hole with the wallet key to program. ALL of this while techstream counter timer is running, you will figure it out.
TIP, shave few seconds off the timer and perform the step sooner than timer allows,

Sorry to hijack the thread but my key just broke off in the ignition. I was able to get it out. The metal key broke off the plastic fob. I still have it all. Do I need to get everything replaced,or can I get a new key only have it cut and put the old guts back in it? Let me know if anybody's got some advice. Thanks

I used another vendor other then sewel it was easier to do and i think it was less money I emailed the following guy gave him my key code you can get your lexus dealer to give it to you or you can just supply the VIN to the vendor . My truck is a 2004 gx you can email the vendor and see if its the same shell the cost shipped was $ 60.00 new shell cut and shipped and is OEM lexus part
