PDQ I5207 VAULT SFIC Core, 7-Pin

PDQ VAULT Patented Keying System SFIC Core, 7-Pin

PDQ VAULT is a patented keying system built around the VAULT Door, a precision engineered tapered gate inside the core that physically blocks unauthorized keys. Only the tapered VAULT key can pass this barrier, so standard keys cannot engage the core. The design is covered by U.S. Patent #12338653, protected through 2044, and unauthorized duplication of VAULT keys is prohibited.

VAULT cores are 7-pin small format interchangeable cores (SFIC) that fit hardware already prepared for SFIC, and VAULT keys still operate standard PDQ SFIC cores. That hybrid compatibility lets a facility phase its upgrade, securing the perimeter first and working inward without disrupting the current system. VAULT keys and cores are supplied only through authorized distributors under PDQ's Key Control Policy.

Frequently Asked Questions

Can VAULT cores be installed gradually without replacing every lock at once?
Yes. VAULT cores fit existing SFIC housings, and VAULT keys still operate standard cores during the transition, so a campus or multi-building portfolio can convert door by door.

When should VAULT be specified instead of PDQ High Security cores?
VAULT fits when the priority is a patent protected keyway with an authorized distributor only key control policy and hybrid SFIC compatibility. PDQ High Security cores provide anti-drill and sidebar pick resistance in a more conventional cylinder format.

Which PDQ products accept VAULT cores?
PDQ lists the MR Series mortise lock, GT and GP Series cylindrical locks, KM Series deadbolt, and 6W, 6C and 4EN exit device trim as compatible.

PDQ I52077 – Frequently Asked Questions

1) Will the PDQ I5207 VAULT core fit locks that already take a small format interchangeable core?
Yes. The I5207 is a 7-pin small format interchangeable core (SFIC), so it drops into any hardware already prepped for SFIC. PDQ names its own MR Series mortise lock, GT and GP Series cylindrical locks, KM Series deadbolt, and 6W, 6C and 4EN exit device trim as compatible. Since it is an interchangeable core, swaps are done with a control key rather than pulling the lock apart.
2) Can I convert a campus to VAULT keying a few doors at a time instead of all at once?
That is what the hybrid keying is for. VAULT cores fit existing SFIC housings, and a VAULT key will also operate standard PDQ SFIC cores, so during the changeover one key carries a user through both converted and unconverted doors. Facilities typically secure the perimeter first and work inward, door by door, without rekeying the whole portfolio in one shutdown.
3) Will a standard SFIC key open a PDQ VAULT core?
No. There is a patented tapered gate inside the core, the VAULT Door, that physically blocks any key except the matching tapered VAULT key. A conventional SFIC key cannot engage the pins. The protection runs one direction only: VAULT keys open standard PDQ SFIC cores, but standard keys do not open VAULT cores.
4) What do I have to specify when ordering a PDQ I5207 VAULT core?
Four things: finish, keyway, and whether you want it combinated or uncombinated. Finish is 626 Satin Chrome or 606 Satin Brass. Keyway choices are V5 and V6 (PDQ VAULT keyways) plus VA, VE, VJ, VK, VL and VM (standard SFIC VAULT keyways). Combinated cores arrive pinned to your keying schedule; uncombinated ships blank for your locksmith to pin on site.
5) Can PDQ VAULT cores be master keyed across a building?
Yes, the VAULT system supports custom master keying, and because the cores are interchangeable you can re-key an opening by swapping the core instead of servicing the lock. Keys and cores are supplied only through authorized distributors under PDQ's Key Control Policy, which is the point of a patented keyway: duplication of VAULT keys without authorization is prohibited.
6) Should I specify PDQ VAULT or PDQ High Security cores?
Pick VAULT when the driver is key control: a patent protected keyway (U.S. Patent #12338653, protected through 2044), distributor-only key supply, and SFIC interchangeability so you can phase an upgrade. PDQ High Security cores are the choice when the threat is physical attack on the cylinder, since they add anti-drill and sidebar pick resistance in a conventional cylinder format rather than an SFIC.
7) Is the PDQ I5207 a 6-pin or 7-pin core, and does that matter for my existing keys?
It is a 7-pin core. SFIC housings accept both 6-pin and 7-pin cores in the same figure-eight prep, so the pin count does not change the hardware, but it does change the key: 7-pin VAULT keys are cut on a 7-pin blank and the tapered VAULT profile is required to pass the core's internal gate. Existing standard keys will not operate it.
8) Which finish of the VAULT core matches the rest of my door hardware?
Two finishes are produced: 626 Satin Chrome, ordered as I52077, and 606 Satin Brass, ordered as I52078. 626 is the usual match for satin chrome or brushed nickel lever trim and exit devices; 606 suits satin brass trim. The core face is the only visible part, so match it to the cylinder collar or lever finish on the door.
9) Is the PDQ VAULT core suitable for commercial and institutional buildings?
Yes, it is a commercial-duty product, BHMA certified, and PDQ points it at large campuses and phased keying system upgrades, which is where distributor-controlled key duplication matters most: schools, healthcare, multi-building portfolios. It is backward compatible with existing SFIC hardware, so standardizing a facility does not mean replacing locks.
