Below is the procedure to erase all keys to start from scratch. This is the procedure using Toyota's Techstream. The person doing the erasure will need to have a valid "Security Professional" subscription to Toyota TIS in order to input the SEED NUMBER and obtain a PASSCODE NUMBER to perform the erasure.
After the keys are erased, then you can program as usual using procedure "A" as shown below.
(e) PROCEDURE "E"
All keys ID erasure
Process
Procedure
1. Start of erasure
1.Connect intelligent tester (with CAN VIM) to DLC3
2.Turn engine switch on (IG)
3.Turn tester on while turning driver side door courtesy light switch on and off repeatedly at 1.5 second intervals or less
4.Select "SMART ACCESS / ID UTILITY / SMART CODE RESET" from tester menu
5.Read "SEED NUMBER" sent from TIS according to tester screen
2. Erasure of ID code
Perform operation according to prompts on tester screen
3. End of erasure
Finish key ID code erasure
(a) PROCEDURE "A"
New key ID registration (when replacing certification ECU and ID code box, or certification ECU, ID code box and steering lock ECU), or when performing all keys ID erasure (key code reset):
Process
Procedure
1. Start of registration
1.Connect intelligent tester (with CAN VIM) to DLC3
2.Turn engine switch on (IG)
3.Select "SMART ACCESS / ID UTILITY / SMART CODE REG" from tester menu
HINT:
Engine switch cannot be turned on (IG) more than 10 times. After connecting tester, turn tester on while turning driver side door courtesy light switch on and off repeatedly at 1.5 second intervals or less to continue key registration procedure.
2. Confirmation of ECU code
Perform operation according to prompts on tester screen
HINT:
Mode is automatically selected by tester, new registration mode or add more
3. Verification of unregistered key *1
1.Hold unregistered key close to engine switch
2.Confirm that wireless door lock buzzer sounds once (short beep)
3.Place unregistered key on front passenger side seat
4.Confirm that wireless door lock buzzer sounds once (short beep)
4. Registration of ID code
Perform operation according to prompts on tester screen
5. End of registration
Finish new key ID code registration
Locksmiths use different scanners that basically avoid having to have a TIS subscripton, or having to use a techstream. Toyota basically wishes they used these tools, as it is much faster, and easier to reset, and reprogram keys.

Can a used Lexus smart key be re-programmed to work for your car? The answer is 100%, abso-effin-lutely YESS!!!
A little background. I recently purchased a 2008 Lexus GS350. Being new to the "smart key" concept I was alarmed when I was warming up my car, and when I walked away the car started beeping. Fearful the car was going to shut off I left the key on the sunroof of my car (I realize now that the car was alerting me the engine was still running instead of warning me it was going to shut off). I come back minutes later and drove off, and only after accelerating to get onto the freeway I hear the keys fall off the roof of my car and the screen on my car alerting me that the key was "out of range". Basically I needed a new key.
Luckily my dad owns a used car wholesale business so I asked my little brother to send me several used Lexus smart keys they had laying around. Making sure the number on the key fob matched the one on my spare.

What compelled me to post this thread is because after taking it to Lexus of Carlsbad and spending 1.5 hours there they were not able to program my keys. According to the service rep the Master Technician said, "There is now way to program used smart keys." And they were going to charge me half of the original quote of $125. I ended up getting it waived, and while I very disappointed, I was happy to get a free car wash.
I then took it to the locksmith option. If you're in San Diego contact Jerry with BusyBee Locksmith in Little Italy, and tell him Vince with the silver GS sent you. I brought the 3 spare keys I had to Jerry, and after about 1-hour of trouble shooting, he was able to program all 4 keys (1 original, 3 used). He would probably be able to do it in 30 minutes or less from now on. Here are some things we learned:
1. The smart keys to be programmed need batteries - for some reason the ones I had didn't have batteries in them and the dealership failed to check. That is unless they removed them.
2. They needed to reset the proxy (proximity) computer.
3. It takes 16 minutes to access and reset the proximity computer - I believe Lexus set this up as a precaution so someone couldn't easily boost your car. It would take at least 16 minutes.
4. When programing the smart keys by touching the Lexus symbol of the fob to the ignition button in your car all other keys should be out of proximity (approximately 3 feet outside of your vehicle) and done one at a time - we noticed when we were programming that the lights on all the key fobs were blinking. This means the computer was confused on which key to program.
I know there are other threads out there on the same topic, but I many weren't detailed and were debating back and forth of whether this is possible. Hope someone finds this useful. Good luck!

You have been the most helpful person by FAR. I have a situation and want to see if that would still work for me. A few months ago my friend threw me my keys but I failed and they fell onto the concrete, busting my fob open. I put it back together and had the Lexus dealership put a new battery in it. Since all of that, I get the "Key not Detected" message and I cannot lock or unlock my vehicle, or open the trunk. Thankfully I am still able to start the car by holding it to the start button and waiting for the beep, then I can press the brake and push the button. If I reset the proxy and reprogram the key, will it work properly again?

Lexus key.
We all tend to put keys here and there and then forget, Sorry pal I Lso have a weak cerebellum if that is where the memory synapses are located, I forget all the time,
I have a lexus GS300 year UK 2005 the fr who sold me told me it was a 2008 ha. Soon proved him wrong.
I need a TrAnsmitter or & key.
Bought one in the USA but my tech cannot programme it. Doesn't take the code when h tries.
He is convinced that Thry gave me a wrong key.
I have tried to get a key from lexus Croydon.
Seems impossible as they say he car has to be there for gem to programme the key.
Is this so ?
I seems to read that A lot of blokes buy keys all the time, and they are sent by mail, and they work fine,
Do tell me.

I own a GS 300 it is my third gS300. The first was Aristo double turbo nice acceleration and whatever,
I now want to buy a car for wife,
I have Lways gone for GS, but lately I see a lot of improvement in the ES,
The final plus was when I saw that the GS is heavy on gas Nd the 3 ES is the ore. Economical.
Which would u advise, I am keen on economy of gas,
I don't need too much speed, nice pick up is nice tho.
What about the hybrid ?

- Purchased 2011 RX450h, it came with one smart key fob (and a mechanical key).
- Called the local Lexus dealer, I was told it will cost ~$350 for a second set ($190 for key fob, $60 to program it, and $100 for the mechanical key)
- After researching , called the local Lexus dealer again, and asked if they can program a used key fob if I buy one on the internet – the service advisor #1 said they could do it, but warned that only if the key fob is the exact same model AND not defective.
- Bought a used keyfob from a reputable seller on ebay, and the fun started.
- Set up an appointment with the local Lexus dealer, brought in the SUV and the key fob – service advisor #2 said they cannot program a “used” key fob, but they will try their best since service advisor #1 had given out incorrect information.
- 2 hours wait – service advisor #2 said the technician was not able to program the key fob.
- Drove to a nearby locksmith, after 15 minutes of hooking up his equipment into my SUV, they were able to detect the key fob, but not able to program it
- Found another locksmith (~25 miles away), it took him 2 times, but was able to program the key fob successfully (via the reset proximity method)
- As for the mechanical key, I found a seller on ebay (1010keys) that sold and cut 2 keys, for $30 shipped.
At the end, my total was $150 ($70 for used key fob, $50 for programming and $30 for 2 mechanical keys), compare to $350 as quoted by the dealer. However, I think a better alternative would be buying the brand new key fob from Sewell (~$132 with the CL member discount) – take your pick: save the $60 and spend 3-4 hours running around from one place to another like I did; or you can take the long route like I did, but remember that a "used" key fob can be programed, as the OP stated...

Is there any validity to the claim that the circuit board inside the key fob has to have matching numbers. most lexus fobs are going to match on the fcc id but not on the circuit board.
