Replacement Locks for Under-Coach Storage Compartments

I replaced my CH751 locks not due to security, but because the key is thin and can break in the lock. I went to an "automotive grade" cylinder set from Amazon (all the keys are the same, but the cylinder uses a shutter and is more dirt resistant. The key is thicker and is less likely to bend or break off as well.

If I wanted real security, I'd buy a set of Medeco or Abloy cylinders... but all that would happen is that the tweaker just would use a long screwdriver on the door and pry it open.
