I too have one of these Yale locks and applying tension is even simpler than pushing on the face. Instead, you can apply tension to the shackle and if you wanted a special tool for these, a spring wedged between the shackle and lock body would suffice.
However I've found it's a lot easier to just shim these from the front as their cylinder face is the same diameter as the hole in the lock body.
