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

- Key cuts cover every level of a master key system, from change key up to great grand master
Technical Specifications
- Manufacturer Part Number: I0241
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 I0241 – Frequently Asked Questions
1) What exactly is the PDQ I0241 VAULT MKC, a key blank or a finished key?
The PDQ I0241 is a factory cut VAULT master key (MKC), not a blank. It arrives cut to a master level combination in the VAULT patented keying system, so it opens every cylinder assigned to that master group while each door keeps its own change key.
2) Will a PDQ VAULT master key work in standard SFIC cores, or only VAULT cores?
VAULT keys operate standard SFIC cores as well as VAULT cores. That is the point of the system: a facility can convert openings to VAULT in phases and keep one master key working across both the converted and the not yet converted cores. The reverse is not true, standard keys are blocked by the patented VAULT door inside the core.
3) Can I get PDQ VAULT keys duplicated at a hardware store or by my local locksmith?
No. VAULT is a patented, closed keyway covered by U.S. Patent #12338653 through 2044, and unauthorized duplication is prohibited. Blanks are not available on the open market, so additional master or change keys have to be ordered through an authorized PDQ source. For a property manager that is the control benefit, keys cannot walk out and be copied at a kiosk.
4) I need a key that opens a single apartment, not the whole building. Is a master key cut the right thing to order?
No. A master key cut opens every cylinder in its group. For one door you want a change key cut, which is the bottom level of the system. PDQ's VAULT cut range covers change, master, grand master, great grand master and control keys, so order by the level you actually need.
5) How many levels of masterkeying does PDQ recommend in a VAULT system?
PDQ recommends no more than four levels: change key, master, grand master and great grand master. Beyond that the number of shared cuts rises and the system gets harder to control and expand. If you are laying out a campus or multi-building portfolio, plan the groups before ordering cuts.
6) What do I have to supply when ordering a PDQ VAULT master key cut?
VAULT is a closed system, so the cut has to be tied to your existing keying records or a new system assignment. PDQ publishes keying system and order forms for exactly that, at https://zensupply.com/content/pdf/pdq/pdq-keying-systems-and-forms.pdf. Expect to identify the system, the master level and the cores the key must operate.
7) Is there a PDQ high security key blank I can buy and cut myself?
Blanks for PDQ high security cylinders are not sold. Those keys are cut at the factory only, covering 6-pin cylinders, 7-pin SFIC cores and 6-pin LFIC control keys on the TA keyway. The VAULT side of the range does include a key blank, but it is still restricted to authorized supply.
8) Is a master key cut the same as a control key for an interchangeable core?
No, they do different jobs. A master key cut operates the locks in its group. A control key removes and replaces the interchangeable core itself without taking the lock apart. PDQ lists control key cuts separately from master cuts, including 6-pin LFIC control keys, so a locksmith standardizing a building usually needs both.
9) Is the PDQ VAULT keying system meant for commercial buildings or houses?
Commercial. PDQ classifies the VAULT and high security key program as commercial door hardware, aimed at facilities running a masterkeyed system with interchangeable cores rather than single-family residential locks.
