2020 Toyota Highlander all keys lost.
If it’s add key, autel is able to add it without LSID. Either way, you can try it. If it shows you 3 data lines, then not possible.
Autel doesn’t support toyota/lexus 2018+ all key lost yet, still in development. 2018 before AKL requires APB112 emulator. As for lonsdor you’ll need to Lonsdor specific smart key and open AKL license on your device which has to be renewed every year.
If all keys lost, it requires Toyota Subscription with techinfo.toyota.com. The newer Toyota’s have an extra security component even adding keys diagnostically will be a problem unless you have the special password. IM608 can do the ’21 Corolla’s and Camry’s (at least) by OBD as long as you can provide the 12-digit outcode. The im608 requires a response code of 12 digits, which comes after you submit the 3 lines of data.
Autel cannot bypass the seed code (LSID). Best bet is Techstream subscription with NASTF.
Its 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. It’s confusing, but that’s how it’s done.
