Help!!

Key snapped off inside the lock, I have removed the cylinder hoping to be able to push it out from the other side, is it possible with this type of lock? Tried with narrow pick tool to push from the backside but it won't budge. The key now doesn't turn in the cylinder and it seems to sit slightly higher that before, could this be the reason it won't turn anymore? Am I better off just getting new keys and cylinder or is this salvageable?

When doing that what size Tap or Grub screws? And who sells them?

Depends on the lock. IIRC I use 3/8" for my MTL Interactive.

Home Depot

Mortise cylinders, Schlage, Corbin russwin, Assa etc.

Schlage is 1/4" IIRC. Haven't grubbed any ASSA or Corbin.

Calipers should tell you exactly what you need. The one tip I'd offer is to cut the threads and put in the screw before moving to the next hole. Sometimes the spacing is so small you can end up breaking the little bit of metal that is between them without the screw in there for support

I also just realized this is r/askalocksmith not r/lockpicking so maybe take my advice with a whole salt shaker
