Good grief ,,, just get a socket about the same size as the missing key socket ,, grind the first few mm down so its thin and works as a leader , put the socket on a six inch extension , beat the socket into the missing key pattern hard ,,,, take the nut off as usual , best bit is now the socket is the right shape for the other three locking nuts , take them off and fit the real ones that are probably still in the boot ,,,, with the missing key ,,, its just how it works out most times ,,,, next.
I'm hoping never to do it again,fingers crossed. My method worked well,we had to cut the outer spinning sleeve first. Then wacked the bolt remover over the remaining bolt. The off she came😅l. But if it happens again I may try your method👍
