larry1, please define "master key" in the context of 2002-2006 vehicles. I have never heard the term used in the dealer for my 2002 ES300, nor is the term "master key" in my user manual at all.
Also, what do you mean by "cut a key"? As far as I know you can cut the physical part of the key, the part that opens the doors, and maybe even the glovebox, but a locksmith cannot provide the programming that will allow the key to start the engine. And, the locksmith will not be able to give you a program that automatically opens doors, moon roof, etc.
Here is the set of keys I received with my car when new. Which of these, 1, 2 or 3, is the "master key"?:
1. 2 keys that include keyless entry. There is a programmable chip in both of these keys, which are identical to one another. All keys and the engine are programmed at the same time so they all have the same program.
You cannot pass programming information from one of these keys to another, and you cannot pass programming information from a key to the engine or from the engine to the key.
Therefore, if you lose one of these keys, you have to have all your keys and your engine reprogrammed if you want them all to work. I suspect you need to take the keys to a Lexus dealer in order to make keys that your engine recognizes, because your engine also needs reprogramming.
2. A valet key, which also has programming in order for the engine to know that the valet key is matched with the engine. This key does not have keyless entry, i.e. cannot auto open the doors, trunk, moon roof etc.
You cannot open the glove box with the valet key, because the glove box has the button that allows the enabling of the trunk button that is near the driver. To keep the valet out of the trunk with the valet key, you must set the button in the glove box to lock the trunk and then lock the glove box with the keyless entry key. The valet will no longer be able to open the trunk with the valet key because the trunk activation feature is disabled by the button in the glove box and the valet cannot get into the glove box with the valet key.
3. A wallet "credit card" key, which also contains the program. There is no keyless entry on this credit card key, but it does open the glove box, allowing you to enable and disable the trunk opening button near the driver.

The 2 keys with keyless entry are master keys. That means they will unluck the trunk and the glovebox lock, where the valet key will not. They are masters, because they operate everyhing. A standard key terminology.
"Cut a key" meant to cut the proper pattern in the metal part of the key.
You are correct, you can not pass programming info from one key to another. And you are correct, the key does not pass information to the engine.
What happens is you insert a transponder key (a key with a transponder [transmitter/responder] inside the head of the key-like the two masters and the valet) that has been programmed to your your car in the ignition cylinder. There is a ring around the ignition key slot that sends a signal from the car's Engine Control Module, aka Engine Control Unit, aka ECM, aka ECU, to the key. This signal does not come from the actual engine. If the key receives that signal and transmits the proper signal back through the ring around the ignition key cylinder to the ECU, then the ECU will allow the engine to start.
Yes, the locksmith does not give you a program. The car already contains the ability to program a new master key. But Lexus wants to keep it a secret, so they can gouge you. The locksmith who posted the page with the info, let the secret out:)
If you read the website link that I gave you, you will see how to delete the stolen keyless entry, also called a remote (control) master, so that the stolen key will no longer start the engine.
I watched all of this done myself on my 2000 ES 300 a few months ago right in front of me at the locksmith's shop in Phoenix. The same guy, Charley, who is the author of the website link I posted in my last post.
I don't know how to program a key so that the remote buttons will operate the sunroof, etc. In order to save a thousand dollars or so, as you stated in your post, aren't you willing to live without that on your spare key? Or call the locksmith on the website and ask him if he knows how to do it.
I haven't seen your wallet key, but I am almost 100% certain that it will not start the engine. That key is useful only if you happen to have that key available when you have locked your other key inside the car.

We had an 02 (or was it 01. . . the old body) ES300. It was a great car and had one of the best stock stereos I've experienced. Seems the salesman told me they didn't bother ordering the upgrade system because the stock one was a 190w Alpine that sounded just as good. When my wife moved to an RX330 in '04 I gave her new sound system points for trying but without a trunk it just didn't have the bass.
Last month we inherited her mom's 06 ES330 (800 miles), and are considering keeping it sinced it only had 800 miles and the RX lease is almost up. I drove it today looking forward to the great sound we got in the old EX. Much as I like the new sedan, that stock stereo sounds like it's made for an easy-listening grandma. Turn it up much and it turns to mush even with that nice sub in the middle behind the back seat. It doesn't sound like it has any power. What happened? My daughter's $22k Honda sounds like a concert hall by contrast.

Larry, how sure are you that the "re-key" instructions that you describe work for the 2002-2006 ES300/330 ?
You said that you watched while it was performed on your 2000 ES model, which could have different electronics than the current model.
Feb 07, 2006 (8:34 pm)
I just bought a new ES330, even with the new model around the corner. The dealer was willing to discount the car $3K. I was trading in a 2001 MB C-Class, which we'd had a few problems with, and wanted the Lexus reliability now. Yeah, I know...having the newest ES would be nice, but I wasn't waiting for the next problem with the Benz to arrive.

You can call Locksmith Charley at 1-800-313-KEYS (5397) 10 a.m. to 6 p.m. Arizona time Monday-Friday and ask him. His website is www.locksmithcharley.com That website doesn't specify any differences for newer models, but you can read it yourself, or better yet, call him. And it isn't re-keying. It is reprogramming the key.

Before I'd go with locksmith Charley, I'd try your local Lexus dealer again. In my experience, the predominant cost of getting a new key is in procuring the replacement key. My Lexus dealer quotes $350 to replace a "master" key plus about $60 for reprogramming your new key plus all your other keys. (Note that larry1's second website advertises replacement keys for $177, less expensive than the $350 quoted by my dealer.)
If you buy a new key from the dealer, you may be able to negotiate the programming for free. I have lost a couple of "master" keys, and have not had to pay for reprogramming yet. The first time, the dealer allowed the price of the replacement key to cover the reprogramming too.
When you get a quote from your Lexus dealer, be sure to differentiate the cost of a replacement key separately from the cost of the programming. If you want to buy a key from the website, inform your dealer because that may impact what the dealer charges you for programming.
If your dealer charges $1000 just to reprogram your key, then you are indeed getting gouged and another Lexus dealer is likely to give you a better deal. Of course, go to locksmith Charley if all else fails, but I think doing it through a Lexus dealer is less risky.
I have a 2002 ES300.

By the way, the wallet key does start the engine. It is there for in case you lose your set of keys while away from your extra keys, so you can access your car before you can replace your keys.

What kind of mpg are you getting on your ES300?
