Here is a case of 2023-2025 GR86 Toyota Subaru BRZ all key lost from Qussi Marji.
Vehicle:
No bypass cable for smartbox
There is no eeprom in it
No Smart box reset
What he tried and failed:
Tried it as a Subaru nothing works
Techstream Will not even recognize the vehicle when the ignition is off The ignition has to be on there is no emergency flashers no opening the door or closing the door will work nothing will work
If you’ve never done this vehicle now you know
Vehicle got towed from Antioch dealership Sat there for a month then towed to Concord dealership then to locksmith then to me.
No one was able to communicate with vehicle because the ignition does not turn on
Solution:
The only way to turn the ignition on is to purchase
Smart box with the key already married to it and the steering lock module
1)Replace smart box and steering lock module
2)Turn ignition on
3)Login with your Techstream account
4)Enter your VSP ID and passcode
5)Program a second key
6)Register CU steering lock
7)Put everything back together and get paid
Tips:
Only Mongoose can communicate the J2534 from Autel IM608 II kept failing when doing security functions
This vehicle has no all keys lost procedure in utility menu in techstream It has immobilizer registration function and it will not approve unless you have a working key because it asks for owner confirmation when you’re adding a key and if you Don’t have a working key That’s how the procedure works
Done! Hope this could help!
