I can offer some help on your key situation. Assuming that the one key you received is a master key (instead of a valet key), you can easily add a remote key, non-remote, or wallet keys. To determine that you have a master key, does the key lock and unlock the glove box and the pass through hatch behind the rear seat armrest. If the answer is "yes", you have a master key. I started with a remote key and a valet key and added a non-remote master key and the wallet key. I purchased my keys from 1010 keys. They are on ebay and are very reasonable and will cut the key from a photo if you don't know the key code. Your car will program the newly cut key. The programming instructions are a little strange but work perfectly. The transponder key instructions for a 2003 Lexus ES300 are:

Key Programming
1. Insert an already programmed master key into the ignition. Do not turn.
2. Press and release the gas pedal 5 times.
3. Press and release the brake pedal 6 times.
4. Remove the key from the ignition.
5. Insert the new key you want to program into the ignition.
6. Press and release the gas pedal one time.
7. Wait 1 minute. The security light will be blinking for this one minute. When it stops blinking your
key is programmed. To end programming step on brake one time.
NOTE: Look for your security light. This light will guide you during the programming procedure. The security light will go off at Step 1. It will remain off until Step 6. The security light will come on and start to blink after Step 6 until the key is programmed. If the security light comes on after Step 4 STOP the procedure and start over again.
If you perform this procedure too slowly your car will not go into programming mode. If you can not get your car to go into programming mode make sure you are using a master key and not a valet key.
If you have a master key then you will probably need to perform this procedure more quickly.
Good luck to you,

Good luck to you,
Thanks for this info! I had no idea how to figure out if I have a master key
So....looks like I got a valet key
I seriously value remote entry, do I have any options at all ??
You have 2 options
well 3 I guess
Cheapest option. Look up how to do the imobilizer hack on your year car
Cheaper option, easier. Buy a master key online then take it to a shop to get cut and have the dealer program it.
expensive but easiest option. Just take it to the dealership and tell them what you need.

some locksmiths can program for a fraction of the dealer cost. we lost our master and he gave us 2 programmed keys for $150

I guess that is a good point. Where I live there is not a single shop within a 2 hour drive that can cut a lexus key let alone program one. But when I traveled to Portland there was 3 different shops that could cut me a key but I didn't ask about programming one.
If time is not an issue, you could ask if the dealership or locksmith would cut keys that aren't sold by them, that way you can get good cheaper keys from eBay.
