PDQ HSC Standard High Security Mortise Cylinder, 6-Pin KD/KA

PDQ High Security Cylinders, Cores and Cams

PDQ High Security cylinders and cores add mechanical barriers that a standard pin tumbler core does not have, resisting drilling, picking and casual key copying. The family covers key in knob/lever cylinders, mortise/rim combo and mortise cylinders, small format (SFIC) and large format Schlage compatible (LFIC) interchangeable cores, and high security cams for the mortise cylinders.

Two levels are offered. Standard High Security cylinders use two hardened anti-drill pins and a proprietary PDQ keyway with a sidebar. High Security cylinders and cores use a minimum of 11 anti-drill and stainless steel pins. Because the sidebar keyway blank is not a standard retail key wall profile, duplication is limited to controlled sources.

Frequently Asked Questions

What makes a cylinder core high security instead of standard?
PDQ High Security cores add hardened anti-drill pins plus a proprietary keyway with a sidebar, mechanical barriers a standard pin tumbler core does not have. A standard core relies on the pin stack alone.

Which PDQ products do the high security cores work with?
PDQ lists them as compatible with its GP, SD and CL Series Grade 2 locks, KV Series deadbolts, and trim including 6T thumb latches, 4P plate pulls, 4GW grip pulls and 6S rose trim.

Is PDQ High Security the same as the VAULT keying system?
No. High Security is a proprietary sidebar keyway with hardened anti-drill pins in a familiar cylinder format. VAULT is a separate PDQ platform built around a patented tapered gate (U.S. Patent #12338653).

PDQ HSC030626 – Frequently Asked Questions

1) What makes the PDQ HSC a high security mortise cylinder instead of a standard one?
The HSC is PDQ's Standard High Security level: two hardened anti-drill pins plus a proprietary PDQ keyway with a sidebar, which is a second locking element working separately from the pin stack. A standard pin tumbler cylinder relies on the pin stack alone. PDQ's upper level, simply called High Security, uses a minimum of 11 anti-drill and stainless steel pins. If you want drill and pick resistance plus controlled key duplication in a familiar mortise format, the HSC is the entry point in that family.
2) Which cylinder length do I need for the PDQ HSC mortise cylinder, 1-1/4 inch or 1-1/2 inch?
The HSC comes in 1-1/4 inch and 1-1/2 inch lengths. Measure the existing mortise cylinder from the face of the trim ring to the back of the cylinder body: 1-1/4 inch is the common length for standard mortise lock bodies on normal commercial doors, and 1-1/2 inch is used where thicker doors or heavy trim set the lock back further. Both lengths are offered in 626 Satin Chrome; 605 Bright Brass and 613E Dark Oxidized Satin Bronze are offered at 1-1/4 inch.
3) Does the PDQ HSC cylinder come with a cam, or do I order that separately?
Cams are a separate item in the PDQ High Security family. PDQ offers high security cams to suit Adams Rite, Accentra (Yale), Russwin/PDQ, Falcon, Schlage and Sargent offset type mortise applications, so you pick the cam that matches the lock body or exit device the cylinder is going into. Get the cam wrong and the cylinder will thread in but will not retract the latch.
4) Can I get PDQ HSC cylinders all on one key for a building, or master keyed?
Keying is a required selection on the HSC: Keyed Different (KD) if every cylinder needs its own key, Keyed Alike (KA) if a set should all operate from one key, or Master Keyed (MK), which carries a master keying charge. One thing to plan for: the HSC is not available 0 bitted, so you cannot order blank cylinders and pin them in house later.
5) Will PDQ high security cylinders work with my existing PDQ locks and trim?
PDQ lists its high security cylinders and cores as compatible with GP, SD and CL Series Grade 2 locks, KV Series deadbolts, and trim including 6T thumb latches, 4P plate pulls, 4GW grip pulls and 6S rose trim. For anything outside PDQ's own line, the deciding factors are cylinder length (1-1/4 inch or 1-1/2 inch) and the correct high security cam for that lock body.
6) Can my tenants get copies of the PDQ HSC key made at a hardware store?
No, and that is the point of it. The HSC uses a proprietary PDQ sidebar keyway whose blank is not a standard retail key wall profile, so duplication is limited to controlled sources. PDQ also does not sell key blanks for its high security cylinders. Each cylinder ships with 2 cut keys, so order enough cylinders and keys for the people who actually need access rather than planning to cut more locally.
7) Should I use a mortise high security cylinder or an interchangeable core for a facility I rekey often?
The HSC is a threaded mortise cylinder, so rekeying means pulling and repinning the cylinder itself. If you rekey frequently or rotate cores between openings, PDQ's High Security line also includes small format (SFIC) cores in 6-pin and 7-pin and a large format Schlage compatible (LFIC) 6-pin core, which swap out with a control key. Note that LFIC mortise and rim housings do not include the IC core, so the housing and core are separate line items.
8) What finishes does the PDQ HSC mortise cylinder come in, and will it match my existing trim?
Three finishes: 626 Satin Chrome, 605 Bright Brass, and 613E Dark Oxidized Satin Bronze. 626 covers the satin chrome and brushed chrome trim most common on commercial openings, 605 matches polished brass, and 613E is the dark bronze used on many exterior entries. If you are standardizing a building, 626 is the one carried in both the 1-1/4 inch and 1-1/2 inch lengths.
9) Is the PDQ HSC cylinder worth it for a server room or narcotics cabinet?
Those are exactly the openings PDQ aims the HSC at, along with evidence and records storage and exterior perimeter entries. The reason is the combination of hardened anti-drill pins and a controlled sidebar keyway, which blocks both the drill attack and the casual key copy that defeats a standard pin tumbler cylinder. It is a commercial-duty part, not a residential one.
10) How do I read a PDQ HSC part number when ordering?
The HSC part number strings the length and finish onto the base model. HSC030626 is the 1-1/4 inch cylinder in 626 Satin Chrome, HSC030605 is 1-1/4 inch in 605 Bright Brass, HSC030613E is 1-1/4 inch in 613E Dark Oxidized Satin Bronze, and HSC050626 is the 1-1/2 inch in 626. Keying (KD, KA or MK) is specified alongside it rather than built into that number.
