About this item

If you're shopping for the Yale 5405, this is it, just under its current name. Yale's commercial hardware became ASSA ABLOY Accentra in 2024, so the AU5405LN you see here is the same lock people have specced as the Yale 5405 for years. It's a Grade 1 cylindrical lockset in the storeroom function with the Augusta lever, and reading the model number tells you most of what you need: AU is the Augusta lever, and the 05 means storeroom function.

What the storeroom function actually does

Storeroom (ANSI F86) is probably the most-specified commercial function, and once you see how it behaves it's obvious why. The outside lever stays locked all the time and needs a key to get in. The inside lever is always free, so anyone inside walks out without a key, which is what keeps the door legal for egress. There's no button to push, no thumbturn to fuss with, nothing for staff to set or forget. Pull the door shut and it's locked again. The latchbolt deadlocks too, so you can't slip it with a card.

That makes it the go-to for storerooms, mechanical and utility rooms, supply closets, and server rooms. Anywhere you want locked-by-default to the public but never want someone trapped inside.

Why people keep specifying the 5400LN

Here's the thing about lever locks: they almost always fail at the lever. A rigid lever that's locked is something a person can crank on, and eventually it loosens, sags, or snaps. The Free Wheeling design on the 5400LN takes that away. When the lock is engaged, the outside lever just spins freely, so there's nothing to wrench against. No leverage, no damage.

That one detail is why this lock ends up on so many schools, hospitals, and public buildings, the places where door hardware takes a beating every single day. And the lifetime guarantee against lever sag covers the exact complaint that sends most lever locks to the scrap pile. For a facility manager standardizing a whole building, that's a lock you install once and stop thinking about.
