When you are trying to program a key for newer Toyota 8A/4A (2018+) proximity all keys lost it will ask you for the 12-digit security code. How to get these codes?

The newer Toyota’s have an extra security component even adding keys diagnostically will be a problem unless you have the special password.
These rolling code changes every time you plug in. You can buy code online directly or have other tools to bypass the pin code.
Bypass method:
Here are top tools that will bypass seed code for Toyota 8A/4A smart key.
1). Autel MaxiIM IM608/IM508 series
Autel MaxiIM had an update for Toyota. It supports back up immo data for 8A smart keys via OBD. The Gbox is not needed. Connect right into the OBD2 port. It did back up the data. Then go into key learning, follow the steps, it asks if back up, click Yes and it went into learning mode. And successfully learn a New key via OBD II without doing a In-code or out-code, or any Password.
2 Ways to bypass pin with Autel:
a. Very simple use apb112 emulator and it takes 5 mins.
You need to generate a master key with the apb112 then use it to add a key.
Autel+apb112+ right key.
Example:
Autel IM508 Program 2019-2022 Toyota RAV4 Free Pin by OBD
b.
You can also do it without the apb112 just have to do a smart box reset and wait the 16min.
Much easier and cheaper to do it with the apb112 way. And besides it can be used for other things also.
Just make sure to have the right key.
If it is a US car, generate Autel ikey universal remote. Just reset smart box then program keys afterwards. Do without 12 digits reset immo. Always 15min or so reset to get access to AKL ! Same with Subaru. And you need to unlock key if you purchase an original used key.
IM608 also release an update for 4A proximity add key and all keys lost free pin code via OBD in May 2023.
2). OBDSTAR X300 DP Plus/X300 pro4
You will need the CAN Direct Kit to bypass rolling code for 8A/4A proximity. The kit contains a Toyota 24 cable (for Corolla 4A) and Toyota 27 cable (for 4A,8A-A9, 8A-AA Toyota vehicles.)
The CAN DIRECT cable and the online calculations are working spot on, no issue 2018 to 2022 on all (A9 A9 and AA AA).
All keys lost requires Key SIM emulator as well.

Buy Code Online
If you don’t have bypass adapters, you can buy code directly.
I. NASTF
Best bet is Techstream subscription with NASTF.
It’s the $65 security professional script. If you have a yearly subscription there is no cost. The yearly subscription costs $1,295.
You can purchase a 2 day subscription at a cost of 65 dollars. Then you have to wait for email ( up to half hours) then you can re-log back in to site and get 1 free key code. It’s much quicker to just pull out the drivers door lock cylinder and get the key code. It’s stamped right on it!
If bypass the seed code, there is no option for all keys lost or generate smart key, only add key, then add the key.
Once you have reset immo, you go back and add key.
