I m not sure, seems they was using a handheld to re programme the ECU but caf battery voltage was too low and ECU locked.

Any possible method to repair or unlock?

Recovery mode with some tool that supports this function, or good tuner could do it with WinOLS and BDM.

Always remember to use extra power when programming cars, capacity of 30-40 amps charging power with a parallel battery connected to the car. Not always needed, but it?s a cheap insurance. This is how I do it and it minimizes this kind of things happening.

The programmer should?ve known this risk.

Hope they fix your car because of their lack of knowledge the car is in this state.
