Using the lock is straightforward. The 4-pin cylinder and dual locking levers make picking or prying a real challenge.

Plus, the keyed-alike feature means one key opens all three locks, which is super convenient for managing multiple entry points. I appreciated how easy it was to lock and unlock, even with gloves on.
