Accentra 451-2 – Frequently Asked Questions

1) What are Accentra 451-2 master pins used for?
They're the master (spacer) pins that go into an Accentra cylinder plug above the bottom pins to create a second shear line, which is how a key besides the change key is made to operate that cylinder. The 451-2 is a .51 size master pin sold 100 to a pack, meant for rekeying work and building or reconfiguring master key systems on Accentra commercial cylinders.
2) The Accentra 451-2 comes in pin number 2 and pin number 4 - what's the difference?
The pin number is the increment the master pin spans, not a different product. A No. 2 master pin is twice the depth increment and a No. 4 is four increments, so the No. 4 lets a master key sit further from the change key cut. Both are ordered the same way in 100-count packs; pick the increment your pinning chart calls for, and most master key work needs several increments on hand.
3) Will these master pins work in a Kwikset or Schlage cylinder?
No. The 451-2 is a genuine Accentra component sized for Accentra cylinder assemblies. Master pin lengths are keyed to each manufacturer's depth increment, so dropping them into another brand's plug gives you cuts that don't reach a clean shear line. Use the pin kit matched to the cylinder brand you're servicing.
4) Do I get everything I need to rekey a cylinder with the 451-2 pack?
No. The pack is 100 master pins in one size only. A full rekey also needs bottom pins in the depths your chart calls for, top (driver) pins, springs, and the plug follower and key gauge to do the work. Order the 451-2 alongside the rest of your pin stock, not instead of it.
5) Can I use these pins to build a master key system across a whole building?
Yes, that's the intended use. Master pins are what let one key open a single door and a master key open every door in the group, and the 451-2 is supplied in bulk specifically for master key system creation and cylinder reconfiguration across commercial facilities. Standardizing on Accentra cylinders throughout the building keeps a single pin stock serving every opening.
6) Is the Accentra 451-2 master pin pack suitable for commercial buildings or just residential locks?
It's a commercial-grade item, catalogued for mechanical lock servicing in commercial settings: office buildings, schools, hospitals, municipal facilities, warehouses, and locksmith field kits. The 100-count pack is sized for shops running repeat rekey programs rather than a single door.
