Top 5 Tools to Bypass Toyota Smart Key 12-Digit Security Code

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?

Toyota 12 Digit Rolling Code

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.



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.
