There is no way for you to go aftermarket i believe be the lexus has a very unique ecu where if you lose the master key the whole ecu gotta be replaced for a new keyless entry:-( so it's either you replace the ecu or you stay with your valet:-) that's one thing you must look out for on these Gs400, never buy one unless theres a master key:-)
Good Luck

you should try calling around to your local locksmiths. Hopefully you'll find one skilled on Lexuses.
They may be able to flash the existing ecu with their locksmith magic for cheaper then the dealer quote to replace the unit.
Search the internet ("lexus ecu or ecm reflash") and you'll find locksmiths that will do this by mail, but it'll probably be easier if you can find someone local to do it so you don't need to remove parts yourself and make sure everything works in one shot.
example I found:

or
http://www.toy-lex.com
or
http://www.transponderkeys.net/ser_lexustoyota.html
...many others

my car came with 1 key.
i bought a blank chipped key + remote off ebay.
i had it cut locally, and the ebay seller even provided instructions on programming the key (you like hit the unlock and lock something like 5 times, touch ur nose, do the macarena and country line dance) some sort of thing like that, i dont quite remember...
but if i remember correctly, the key+remote (denso) cost about 70 bucks, cutting cost me about $20 bucks, programming was free (did it myself via the instructions)
dealer wanted 350 for the key, 50 bucks for programming, 50 for cutting.

You can get aftermarket key off ebay and cut them at the dealer(I have Sewell of Fort Worth cut it twice and charge me like $15 each). Second, you also can buy an already cut key off ebay with a tramsmitter(make sure it's the correct part numbers for your car). Put the transmitter into your new cut key and use your wallet key to re-program your key(you can use the tramsmitter that come with the wallet key to re-program your master key), just put the tramsitter next to the ignition when they tell you to put your master key in. Trust me I don't it before and they work. Not that I don't have a master key, but I try it before and they work. Good luck!!

So let me get this straight, when initially programming the new master key... you put your new cut master key (without new transponder in) into the ignition and had the valet key next to it so that the car would read the valet transponder? In sense this would be the first part where they ask you to put in your old master key in.
Just follow the instructions and when they tell you to put the master key in, you use your wallet key+transponder that goes with the wallet next to each other.

2 points:
1) You WILL need a master key otherwise you will need to get ecu/ecm work done.
2) The card key (wallet key) is a master key. It is not the same as a valet key.
The http://www.toy-lex.com site seems to have the programming instructions, although searching CL will also bring up random instructions.

That is a wallet key/card key. It is also a master key. It is not a valet key
