PDQ HSC320 High Security Mortise/Rim Combo Cylinder 1-1/8" 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 HSC320626 – Frequently Asked Questions

1) Will the PDQ HSC320 cylinder fit both a mortise lock and a rim exit device?
The HSC320 is a 1-1/8 inch mortise/rim combo cylinder, so the same body covers a rim exit device and short mortise applications at that length. If you need a deeper mortise cylinder, PDQ's High Security line also runs 1-1/4 inch and 1-1/2 inch mortise formats. For mortise use, the cam has to suit the lock, and PDQ offers high security cams for Adams Rite, Accentra (Yale), Russwin/PDQ, Falcon, Schlage and Sargent offset type applications.
2) Can I key the PDQ HSC320 into my existing building master key system?
Only if that system is already on PDQ's proprietary High Security sidebar keyway. The keyway is proprietary with a sidebar as a second locking element, so it won't integrate with a Schlage, Sargent or other standard keyway system. Within PDQ High Security, you choose keyed different, keyed alike, or master keyed (master keying charge applies) when you order.
3) Does the HSC320 high security cylinder come with keys, and can I buy blanks to cut more?
Two cut keys ship with the cylinder. Key blanks for PDQ high security cylinders are not sold, and the cylinder is not available 0 bitted, so additional keys have to come through controlled sources rather than a retail key wall. Order the full key count you need up front if you have multiple users per door.
4) Which PDQ locks will the HSC320 work with?
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 a rim exit device, the 1-1/8 inch combo body is the right length.
5) What is the difference between PDQ Standard High Security and High Security cylinders?
Pin count is the dividing line. Standard High Security uses two hardened anti-drill pins plus the proprietary PDQ sidebar keyway. High Security uses a minimum of 11 anti-drill and stainless steel pins. Both add mechanical resistance to drilling and picking that a plain pin tumbler core relies on the pin stack alone to provide.
6) Should I use the HSC320 cylinder or an interchangeable core for a facility where staff turn over often?
For frequent rekeying, an interchangeable core is easier because you swap the core instead of pulling the cylinder. PDQ's High Security family includes SFIC cores in 6-pin and 7-pin plus an LFIC Schlage compatible 6-pin core. Note that LFIC mortise and rim housings do not include the IC core, so the housing and core are ordered separately. The HSC320 is the fixed-cylinder option, which suits doors you don't expect to rekey often.
7) What finishes does the PDQ HSC320 come in to match existing door hardware?
Three: 626 satin chrome, 605 bright brass, and 613E dark oxidized satin bronze. The ordering number appends the finish code, so satin chrome is HSC320626, bright brass HSC320605 and dark oxidized satin bronze HSC320613E.
8) Is the PDQ HSC320 suitable for commercial openings like server rooms and pharmacy cabinets?
Yes, it is a commercial-rated cylinder, and PDQ cites server and data rooms, evidence and records storage, pharmacy or narcotics cabinets, and exterior perimeter entries as typical applications. The restricted sidebar keyway is the reason it suits those spaces, since casual key duplication is limited to controlled sources.
