BURSTCATCH works with the original lock by replacing the catch.

Simple one time only installation, and you will never have to replace
a damaged lock ever again! The vandal resistant toilet lock catch will only burst open after a
certain amount of pressure is applied to the door. The lock will then
reset and will work as normal.

If installed correctly no damage will be made to the door or lock.

Depending upon circumstances this lock could easily save you up to 5 or more
times the initial purchase price within the first year.
