didn't make that out from the thread .. so once I manage to release the lock and register as unlocked it should be ok, until it sticks again

yes, I'd recommend going for a drive along a bumpy gravel road

If I could get it started

see the photo in the first post. with the ignition on use a piece of wire between the relay connections which are on the left & right in the photo. you only need to make the connection to start the engine, then disconnect again. Hence way one end is fixed and the other is free
if its the same problem you should be able to start the engine that way

cheers
