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.

Key Features

- 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

- Key cuts cover every level of a master key system, from change key up to great grand master
Technical Specifications
- Manufacturer Part Number: HSC874
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 HSC874 – Frequently Asked Questions
1) Is the PDQ HSC874 a key blank or a key cut to a code?
The HSC874 is a factory-cut key, not a blank. PDQ cuts high security keys at the factory and does not sell blanks for its high security cylinders, so you order the HSC874 against your keying records rather than having it originated locally.
2) Will the PDQ HSC874 work in a 6-pin cylinder or only a 7-pin SFIC core?
It is the 7-pin SFIC core version. PDQ's high security cut keys are offered separately for 6-pin cylinders, 7-pin SFIC cores, and 6-pin LFIC control keys on the TA keyway, so if your cores are 6-pin or LFIC you need the matching cut key instead of the HSC874.
3) Is a PDQ high security SFIC key the same thing as a VAULT key?
No. PDQ runs two separate closed systems: VAULT, the patented keying system with tapered keys, and the PDQ high security cylinders and cores. The HSC874 belongs to the high security side. VAULT keys are tapered to pass a patented door inside the core that blocks standard keys, and VAULT is covered by U.S. Patent #12338653 through 2044. If your cores are VAULT, order VAULT cuts, not a high security cut key.
4) Can I just have a local locksmith duplicate this PDQ high security key?
Not practically. PDQ does not sell blanks for its high security cylinders, and all high security keys are cut at the factory. Additional copies come from PDQ through an authorized channel, which is the point of a restricted system: keys and cores can only be ordered with authorization.
5) Can one of these PDQ keys be a master key for a building, or only a single door?
PDQ high security key cuts cover every level of a master key system, from change key up through master, grand master and great grand master. Which level a given key operates is set by the cutting on your keying schedule, so specify the level when you order. PDQ recommends keeping a system to no more than four levels.
6) Do I need to send keying information when ordering PDQ high security keys?
Yes, because these are factory cuts tied to an existing system. PDQ publishes its keying systems and order forms as a document, and you supply the system and key level details on that paperwork. See PDQ Keying Systems and Forms at https://zensupply.com/content/pdf/pdq/pdq-keying-systems-and-forms.pdf
7) We want to move a building to VAULT gradually. Do we have to rekey everything at once?
No. VAULT keys also operate standard SFIC cores, so a facility can convert in phases, swapping cores as budget and access allow while one key set keeps working across both. That is a VAULT-system property; a high security cut key like the HSC874 operates the PDQ high security cores it was cut for.
8) Is this PDQ key suited to commercial buildings or residential use?
It is commercial door hardware. PDQ classes the high security SFIC cut key as a commercial item, which fits its usual home in schools, multi-family, healthcare and government facilities where a restricted small format interchangeable core system is already in place.
