PDQ VAULT and High Security Keys and Key Cuts
These are PDQ factory keys for two closed key systems: the VAULT patented keying system and PDQ high security cylinders and cores. The range covers the VAULT key blank and VAULT master, grand master, great grand master, control and change key cuts, plus high security cut keys for 6-pin cylinders, 7-pin SFIC cores and 6-pin LFIC control keys on the TA keyway.
Key Features
- VAULT keys are tapered to pass the patented VAULT door inside the core, which blocks standard keys
- VAULT is covered by U.S. Patent #12338653 through 2044, and unauthorized duplication of VAULT keys is prohibited
- VAULT keys also operate standard SFIC cores, so a facility can move to VAULT in phases
- High security keys are cut at the factory; blanks for high security cylinders are not sold
- Key cuts cover every level of a master key system, from change key up to great grand master
Technical Specifications
- Manufacturer Part Number: HSC965
Frequently Asked Questions
What is a restricted or patented keyway?
A restricted keyway uses key blanks set aside for limited use, so keys and cylinders can only be ordered with authorization. A patented keyway adds legal protection: PDQ VAULT is covered by U.S. Patent #12338653 through 2044, and only authorized distributors can supply VAULT keys and cores.
How does a master key system work?
A master key system groups locks so one key opens many doors while each door keeps its own change key. Levels run from change key to master, grand master and great grand master keys, and PDQ recommends no more than four levels.

PDQ HSC965 – Frequently Asked Questions
1) What does the PDQ HSC965 control key actually do?
The HSC965 is a factory-cut control key for PDQ high security large format interchangeable core (LFIC) cylinders on the TA keyway, 6-pin. A control key is what pulls the core out of the housing, so it is the key you use to swap cores during a rekey or a tenant turnover. It does not operate the lock as an operating key.
2) Will the PDQ HSC965 control key work on SFIC cores?
No. The HSC965 is cut for 6-pin LFIC control, and large format and small format cores are different formats with different control key geometry. PDQ's high security range also covers 7-pin SFIC cores, so for small format you need the SFIC-specific key cut, not this one.
3) Can I order blank PDQ high security keys and cut them myself?
No. PDQ high security keys, including the HSC965 control cut, are cut at the factory only, and blanks for the high security cylinders are not sold. If you need field-duplicatable blanks, PDQ sells a VAULT key blank instead; the VAULT system is the one with a blank in the range.
4) Is the TA keyway restricted, and do I need authorization to buy this key?
PDQ high security and VAULT keys come out of closed key systems, which means keys and cylinders are supplied only with authorization through authorized distributors. VAULT specifically is patent protected under U.S. Patent #12338653 through 2044 and unauthorized duplication is prohibited. Plan on providing authorization for the keying record when ordering a control key like the HSC965.
5) Should I go with PDQ VAULT or PDQ high security cylinders for a new building?
VAULT is the patented route: its keys are tapered to pass a patented door inside the core that blocks standard keys, and the patent runs to 2044, so duplication is legally controlled. It also has a key blank available and VAULT keys still operate standard SFIC cores, which lets a facility convert in phases rather than all at once. PDQ high security cylinders and cores are the other path, with factory-cut keys only and no blanks sold, covering 6-pin cylinders, 7-pin SFIC cores and 6-pin LFIC control keys on the TA keyway, like the HSC965.
6) How many master key levels should I plan for in a PDQ system?
PDQ recommends no more than four levels. The levels run change key, master, grand master and great grand master, and PDQ cuts keys at every one of those levels. A control key such as the HSC965 sits outside that hierarchy, it exists to remove cores rather than to open doors.
7) What do I need to submit to get a PDQ control key cut correctly?
Because these are closed-system factory cuts, the order has to tie to your keying record: keyway (TA for the HSC965), pin count (6-pin LFIC), and the system it belongs to. PDQ publishes its keying systems and order forms so you can document the system levels and cuts before the order goes in.
8) Is the PDQ HSC965 key meant for commercial or residential use?
Commercial. The HSC965 is a door hardware item for high security interchangeable core systems, the kind of keying a property manager, locksmith or facility MRO buyer standardizes across a building.
