The steering lock in my Renault Megane 3 2010 would stay locked sometimes. I don’t know for what reason. The dashboard would say “ Turn steering wheel and start” but when I did that nothing would happen. Inserting the keycard would not release the steering lock, the steering wheel would move only maybe 1-2cm left and right. After visiting couple of forums, I tapped/ hit the steering lock with a hammer couple of times and disconnected the battery for maybe 3-4 hrs. And when connected everything again and tried, the steering wheel unlocked and the car started normally. Decided to remove the steering lock (obviously when unlocked) and install the steering lock emulator. It works like a charm. 😎
