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 I02405 – Frequently Asked Questions
1) What exactly is a PDQ VAULT change key cut, and is it a blank or a finished key?
PDQ I02405 is a factory-cut VAULT change key (CKC), not a blank. A change key is the lowest level in a master key system: it operates one specific door or cylinder, while the master key above it opens that door plus others. It arrives cut to the keying assignment you submit, so it is ordered against a specific keying schedule rather than cut locally.
2) Can a locksmith duplicate PDQ VAULT keys, or do they have to come from the factory?
VAULT is a closed, patented keying system. It is covered by U.S. Patent #12338653 through 2044, unauthorized duplication is prohibited, and only authorized distributors can supply VAULT keys and cores. Plan on ordering additional change keys through the factory channel rather than having them cut on a local machine.
3) Will a PDQ VAULT key work in the standard SFIC cores already in my building?
Yes. VAULT keys also operate standard SFIC cores, which is what lets a facility convert in phases: swap VAULT cores into the highest-security openings first and keep issuing VAULT keys that still run the existing small format interchangeable cores. The reverse is not true, since the tapered VAULT key is required to pass the patented VAULT door inside the core that blocks standard keys.
4) I need masters as well as individual door keys for a PDQ VAULT system. What else do I order alongside the change key cuts?
The VAULT line covers every level of the system, not just change keys. Beyond the CKC you can order VAULT master, grand master, great grand master and control key cuts, plus the VAULT key blank. PDQ recommends no more than four levels in a master key system, so a typical build is change key, master, grand master and great grand master.
5) What makes the VAULT key physically different from a regular SFIC key?
The key is tapered so it can pass the patented VAULT door built into the core. That internal door blocks a standard, untapered key from entering far enough to operate the plug, which is the mechanical basis of the system's key control.
6) Can I buy blanks for PDQ high security cylinders and cut them myself?
No. PDQ sells high security keys only as factory-cut keys; blanks for the high security cylinders are not sold. A blank is available for VAULT, but the high security 6-pin cylinder, 7-pin SFIC core and 6-pin LFIC control keys on the TA keyway all come cut from the factory.
7) What is the difference between a restricted keyway and a patented keyway like PDQ VAULT?
A restricted keyway means the blanks are set aside for limited use, so keys and cylinders can only be ordered with authorization. A patented keyway adds legal protection on top of that. VAULT is patented under U.S. Patent #12338653 through 2044, so duplication is both mechanically restricted by the tapered key and prohibited by patent.
8) Is this a commercial-grade keying product or something for residential use?
It is a commercial door hardware item. The VAULT change key cut belongs to a patented, distributor-controlled keying program built for facility key control, which is why it is specified on institutional, multi-family and MRO jobs rather than sold as a consumer key.
9) Where do I find the PDQ keying forms I need to submit with a VAULT key order?
PDQ publishes a keying systems and forms document covering its keying programs, available at https://zensupply.com/content/pdf/pdq/pdq-keying-systems-and-forms.pdf. Since change key cuts are made to a specific keying assignment, that paperwork is what defines which door the I02405 key will operate.
