Not sure if there is still a retailer on EBay that will sell you a key shell with the blade cut to work using a photo you supply. That's how I added two keys to my SC430. Think is was like $30 for both cut shells, shipped. I do see a few that will cut with the 5 digit key code.

Please Help.... I Don't Want to Buy Wrong Key
I know this subject has been discussed at many times on this Forum, however I have searched and search and can't find the information I really need to buy the right key for my car. Can someone please help me?
My car: 2004 SC430
The dealer promised me a 2nd key with programmed remote (fob) but after 3+ weeks of calling these jerks I have finally just given up and will purchase a key w/fob and have the blade cut here locally and then try to program myself.
On e-bay I see two different but similar looking keys w/3 button fobs that both say will fit my car.
One says its fits: HYQ12BBK and the other says it fits: HYQ1512V
My current and only master key looks exactly like both of these keys but does not have any FCC or part numbers on it. Can someone please tell me if either or one of these keys is the correct one that I need so I don't have to go to the dealership and get raped for $225 for just the key, no cutting or programming which is extra. Thank so much

Look up the FCC codes here
https://fccid.io
I know HYQ12BBT works on your car, I programmed that key to my car.

Two different security light flashing sequences but still won't program new key
Avihi, you will need to program the key to your car once you swap the guts. I have attached the procedure to program the transponder. If the transponder isn't programmed your car won't start. You will only need the procedure on the 2nd page (actually page 1) The first page is for programming the remote which you won't need to do. Note, sometimes it takes more than one try to get it to work.
Any thoughts on why my new key won't program?

New key won't program
I have attempted to program a new key several times. During two attempts the red security light has flashed differently. It flashes twice quickly followed by a third flash. It repeats this over and over but never stops flashing. During the other attempts, the security light flashes a steady on and off at about a 1 second interval.
In both situations I have waited over 2 minutes and the security light never stops blinking.
Any thoughts from those that have had success? Do I need to erase all the keys first?! I have two working keys and am concerned if I erase them, I'll never get the car started again.

I've followed the programming procedures 4 or 5 times. Each time the security light never stops blinking. However, during one programming attempt, the security light flashed differently. Instead of a a steady flashing of approximately one second, it flashed two times quickly followed by a third flash. It continue until I removed the new key and re-inserted the original key.

what does TechStream tell you?
if you don’t have it, order it up for less than $25 from eBay or amazon and delete all of those old keys.

Bgw70 is correct. You'll need to perform the reset function and add your keys back in to the system.

Guys, we sell the replacement FOB shell. No key cutting, no programming necessary.

I bought a TechStream cable/software for my Prius and it worked well when I used it several months ago. Unfortunately, it won't connect to my Lexus. I receive the infamous "cannot connect to VIM' error. I noodled around with this for a while and gave up. I now have two working keys and a brand new key that I had cut for the car but I can't program.

I selected XHorse again and toggled between XHorse and TIS TechStream. I tried them both a few times. Still no luck. And I don't see an option for downloading the XHorse driver. Not sure how to do this.
