Twizy fault memory lock active

Sounds familiar! Had something similar with my old Peugeot 208. An error was stored in the error memory, due to the car having undervoltage. Maybe your battery is low?

Undervoltage, huh? What does it mean?

Basically, the car's computer, the ECU or control unit, detects that the voltage supplied by the battery is too low. In my case, I needed to go to the workshop to have it fixed. I would do the same.

Thanks for the tip! Turns out it was undervoltage. Had to get it sorted at a garage, cost 240€. All good now!
