Schlage 22-644 E 626 – Frequently Asked Questions

1) What door thickness does the Schlage 22-644 deadbolt cylinder work on?
Doors from 1-3/8 to 1-3/4 inches, which covers standard commercial 1-3/4 inch doors and the older 1-3/8 inch interior thickness. Thicker than that and the length is wrong for this one; the Schlage modular cylinder platform handles thicker doors through six available rear housing lengths, so the rear housing is the part that changes, not the cylinder.
2) Does the Schlage 22-644 cylinder come keyed, or does a locksmith have to key it?
It ships 0 bitted, meaning the cylinder is supplied without a working key combination, and two keys come with it for cutting once it is pinned. For anyone running a master key system that is the version you want, because the cylinder gets pinned into your existing system rather than arriving on a factory combination you would have to strip out anyway.
3) Which keyway do I order so a new Schlage B660 cylinder works on the keys my building already uses?
Order the keyway your existing Schlage keys are cut on. The 22-644 is offered in the conventional keyways C, E, F, G, EF and FG, plus the multi-section C and S keyway groups such as C123, C145, S235 and S345. The modular cylinder supports interchangeability between Everest 29, Primus XP and Classic key systems, so an existing Schlage system can be carried forward instead of restarted. Keyway and finish are two separate choices on the order.
4) What finishes is the Schlage 22-644 cylinder available in, and will it match the deadbolts already on my other doors?
Four finishes: 606 satin brass, 622 matte black, 626 satin chrome and 643E aged bronze. The front housing is what carries the finish and Schlage offers it in all finishes to match the locks, so the visible cylinder face can be brought in line with the deadbolt trim on the rest of the openings rather than leaving one door looking different.
5) Is the Schlage 22-644 a complete deadbolt or just the cylinder?
Cylinder only. It is a 6-pin replacement cylinder for B660 and B663 deadbolts, supplied with two keys. The deadbolt body, bolt and strike are not part of it. Buy it to replace a worn or compromised cylinder, or to move a deadbolt onto a different key system, without taking the deadbolt off the door.
6) Can a Schlage modular cylinder be converted for a mortise lock or a rim device instead of a deadbolt?
The platform is built for it. One modular cylinder converts to three cylinder types by changing the tailpiece, cam or rear housing, covering mortise, rim and key-in-lever or key-in-knob applications. The 22-644 as supplied is configured for B660 and B663 deadbolts, so a conversion means ordering the right rear housing and the correct tailpiece or cam for the new application. For a locksmith stocking a van, that is the point of the system: fewer parts carried, and most Schlage cylinder types assembled on site.
7) The opening has a mortise lock rather than a B660 deadbolt. Which cylinder should I be ordering instead of the Schlage 22-644?
The Schlage 22-644 is configured for the Schlage B660 and B663 deadbolts, so a mortise lock case calls for a mortise cylinder. The Corbin Russwin 1000 is a Grade 1 series mortise cylinder at 1-1/2 inch length with an A02 straight cam. The Corbin Russwin 1070 is a Grade 1 series 1-1/4 inch 6-pin mortise housing with an A01 cloverleaf cam. The Detex MC65 is a 1-1/8 inch 6-pin commercial grade mortise cylinder cut to the Schlage C keyway. On a mortise job the two dimensions that decide the order are the cylinder length and the cam, both of which are set by the lock case, not by the door.
8) Is there an equivalent replacement cylinder for a Schlage B660 or B663 deadbolt besides the Schlage 22-644?
The Schlage 22-644 is the 6-pin cylinder matched to the Schlage B660 and B663 deadbolts, and it covers doors 1-3/8 inch to 1-3/4 inch thick. The nearest cross-brand parts are aftermarket deadbolt cylinders: the Kaba Ilco 1549 Series is a key-in-deadbolt cylinder, and the Medeco 1075127 is a 5-pin rim type lazy motion single cylinder made for handlesets and deadbolts. Those two are built to a general deadbolt cylinder pattern rather than to the Schlage B-series body the 22-644 is cut for, so a locksmith swapping one in should confirm tailpiece engagement and pin count against the deadbolt in the door.
9) Is there an interchangeable core option if I want to rekey a facility without pinning cylinders?
The 22-644 is a 6-pin cylinder, so rekeying it means pinning the cylinder. If the goal is pulling a core with a control key and dropping a new one in, look at BEST small format interchangeable core instead: the 1C Series standard 5-pin core, the 1CB 150 Series Peaks core, or the 1CDF drill resistant patented 7-pin brass core in the 150 Series. For large format on Schlage L9000 mortise locks, Corbin Russwin's 1080 Series 1-1/2 inch LFIC mortise cylinder is 6-pin with an A01 cam. Interchangeable core costs more up front and pays back on turnover-heavy properties.
10) A Corbin Russwin cylinder is described as being for Schlage locks. Can I put it in my B663 deadbolt in place of the Schlage 22-644?
Those are two different lock families that both carry the Schlage name. The Corbin Russwin 1080 is a 1-1/2 inch LFIC mortise cylinder, 6-pin, built for Schlage L9000 mortise locks with an A01 Schlage L cam, so it drives a mortise lock case. The Schlage 22-644 is the 6-pin cylinder for the Schlage B660 and B663 deadbolts on doors 1-3/8 inch to 1-3/4 inch thick. A cam that turns an L9000 mortise lock has nothing to engage in a B-series deadbolt, so match the part to the lock chassis in the door rather than to the brand on the key.
11) All the doors in the building are keyed to one Schlage key. Which cylinders can join that same system?
The Schlage 22-644 is ordered by keyway, including C, E, F, G and EF along with the restricted C and S three-digit families such as C234 and S345, and the Schlage modular cylinder platform supports interchangeability between Everest 29, Primus XP and Classic key systems. If a mortise opening needs to fall under the same Schlage C key, the Detex MC65 is a 6-pin commercial grade mortise cylinder cut to the Schlage C keyway. The Falcon A23161-05 G is a 6-pin key in lever cylinder in the G keyway. Keyway family is what determines whether a cylinder can be brought into an existing system, and it is chosen at the time of order on each of these.
12) Do these cylinders arrive cut to a key or do I pin them at the bench?
The Schlage 22-644 ships 0 bitted in every keyway offered, from the C, E, F and G keyways through the restricted C and S families, with two keys included. That leaves the bitting to the locksmith so the cylinder can be brought into whatever system the building already runs. The Falcon A23161-05 G takes the other route: it is a 6-pin key in lever cylinder in the G keyway supplied keyed different with two cut keys, ready to hand over as its own key. Which one suits depends on whether the opening is joining an existing keying schedule or standing alone.
13) We want maintenance staff to rekey doors in-house without pulling the hardware apart. How does that compare with running the Schlage 22-644?
The Schlage 22-644 is a 6-pin cylinder for the Schlage B660 and B663 deadbolts, and the modular platform behind it changes cylinder type by swapping the tailpiece, cam or rear housing, which is a bench operation on the cylinder itself. An interchangeable core program works differently: the core comes out with a control key and a new one goes in. On that side the BEST 1CB Peaks is a 150 Series interchangeable core cylinder, the BEST 1CDF is a drill resistant patented interchangeable core in 7-pin brass 150 Series, and the BEST 1C is a standard 5-pin cylinder core. The Corbin Russwin 1080 carries the same idea in mortise format as a 1-1/2 inch LFIC cylinder. Standardizing a facility on one of those means committing to a core format and a control key across the doors.
14) The deadbolt on the door is a Kwikset, not a Schlage. Is the 22-644 still the cylinder to order?
No. The Schlage 22-644 is the 6-pin cylinder matched to the Schlage B660 and B663 deadbolts. For other manufacturers' deadbolts there are purpose-built retrofit cylinders: the Medeco 1012040 is a 6-pin lazy motion rim cylinder for Kwikset single cylinder deadbolts, the Medeco 1065140 is a 5-pin retrofit cylinder for the Arrow JL interconnected lock and the Emtek handleset and deadbolt outside cylinder, the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece, and the Emtek CY4 is Emtek's own cylinder. The deadbolt brand and body determine the tailpiece, which is why these are not interchangeable across makes.
15) Half our doors take a key in the lever rather than a deadbolt. What do I order for those?
The Schlage 22-644 is the deadbolt configuration, built for the Schlage B660 and B663, and the modular platform it belongs to is adaptable to mortise, rim and key-in-lever or key-in-knob applications by changing components. For a lever or knob opening served by a separate part, the Kaba Ilco 1539 Series is a key-in-knob and lever universal cylinder, the Kaba Ilco 1599 is a key-in-knob replacement cylinder, the Kaba Ilco 1579 is a knob and lever cylinder for Sargent, and the Falcon A23161-05 G is a 6-pin key in lever cylinder in the G keyway from the RU/T series. Match the cylinder to the lockset make on each door, since the tailpiece is what differs between them.
16) The job spec calls for a 5-pin cylinder. What are the options against the 6-pin Schlage 22-644?
The Schlage 22-644 is 6-pin across every keyway and finish it is built in. Where a spec is written around 5 pins, the Adams Rite 4036 is a five-pin mortise cylinder in the 4036 Series, Grade 1, with a 1/2 inch minimum door thickness. The BEST 1C is a standard 5-pin cylinder core. The Medeco 1075127 is a 5-pin rim type lazy motion single cylinder for handlesets and deadbolts, and the Medeco 1065244 is a 5-pin rim lazy motion cylinder with an Emtek tailpiece. Pin count is fixed by the cylinder, so it is decided at the order, not adjusted in the field.
17) The exit device on the stair door takes a rim cylinder. What covers that opening?
The Schlage 22-644 is set up as the deadbolt cylinder for the Schlage B660 and B663, though the modular platform behind it converts to three different cylinder types by changing the tailpiece, cam or rear housing. Where a rim device needs a ready-built part, the Corbin Russwin 3070 is a 6-pin rim cylinder housing with a 1-7/8 inch tailpiece, and the Medeco 1012040 is a 6-pin lazy motion rim cylinder. On a rim application the tailpiece length is the figure that has to be checked against the device.
18) Our doors are thicker than a standard 1-3/4 inch slab. Does that rule out the Schlage 22-644 in favor of another cylinder?
The Schlage 22-644 is listed for doors 1-3/8 inch to 1-3/4 inch, and the modular cylinder platform it comes from accommodates thicker doors through six available rear housing lengths, so thickness is handled by the housing rather than by moving to a different cylinder family. Among the mortise-format peers the Adams Rite 4036 five-pin cylinder works from a 1/2 inch minimum door thickness, which reflects the narrow stile aluminum doors that series is aimed at. Confirm the slab thickness and the lock type together, since one drives the housing length and the other drives which cylinder format the door needs.
