Keys
These keys can be cut as they are a standard locker/garage door key.  The main difference is that they have a slot along then which nearly locksmiths cannot cut.
This slot can be ground out with a Dremel but it's not a nice job.

The easiest way is not to cut the slot in the key but to file off the nib on the front of the lock barrel, where the key slot locates.

To do this:-

  1. Lay the lock on a flat surface facing upwards.
  2. Remove the two screws.
  3. Lift the cover from the lock.
  4. The barrel should remain standing in the middle.  Just lift out.
  5. The barrel is made of alloy and the nib is at the front end and will file away easily using a small flat file.
  6. Test the barrel by sliding the key in.
  7. Replace the barrel into the lock.
  8. Replace the cover and fix with the two screws.
