We have an original working remote key and we need to add a spare 8A Texas Crypto 128-bits smart key (original key) to a Land Cruiser 2023 using OBDSTAR X300 DP plus.
Go to Immobilizer-> Toyota Lexus Scion->Latest software version->Manual Sselect system->Proximity->Type 8 (CAN)
Read key numbers, there are 2 keys already. We are going to make 3rd key.
The function requires network connection
Turn on ignition switch with working key.
x300 dp plus asks for 12-digit security code.
You can get the code from 3rd party. Here we have the security code, you can also try to backup immo data via obd, if failed, use the security code.
Place a programmed key close to Start button
Program key completed.
Test the remote.
*OBDSTAR will add key and program all keys lost on Land Cruiser 2022-2023 if page is 8A-AA or 8A-A9. It cannot do 8A-BA.
