Peter - You might be able to remove the barrel and replace it with a standard pinball lock. Just ensure the tongue fits. I'd remove the locks and measure the depth. If it is the same depth, then it should be easy. I don't have that lock, but we should still be ok..

Pinball lock or arcade lock?

The type of lock mech in the photo takes a standard barrel type arcade lock with a 6mm threaded shaft with flats on both sides.
It should be 22mm long.
