Mortise Cylinders
The mortise cylinder is the part your key goes into. It threads into the lock body, which means it can be swapped or upgraded quickly without replacing the whole lock.

Mortise cylinders come in different lengths and cam styles. Matching both is what makes the swap work, especially on thick metal apartment doors.
Upgrade path
Moving to a high-security mortise cylinder is a common way to improve an apartment door without changing the lock body.
