PDQ I5304 LFIC Mortise Cylinder Housing, Schlage Compatible
PDQ Interchangeable Core Mortise and Rim Cylinder Housings
PDQ interchangeable core housings let a mortise or rim cylinder location accept a removable IC core. The range includes Best compatible small format (SFIC) mortise housings in 1-1/4, 1-3/8 and 1-1/2 inch lengths, including tapered versions, an SFIC rim housing for 6-pin or 7-pin cores, and Schlage compatible large format (LFIC) mortise and rim housings. Cores are ordered separately, so the housing can be paired with the PDQ core and keyway that fit the building's key system.

Frequently Asked Questions
What is an interchangeable core?
An interchangeable core lets the entire keyed core be pulled out of the lock with a control key and replaced with a new one, without removing the lockset from the door. PDQ positions this as a way to restore security quickly when keys are lost or stolen.

PDQ I5304626 – Frequently Asked Questions
1) Does the PDQ I5304 come with a core, or do I need to order one separately?
Housing only. The I5304 is a mortise cylinder housing that accepts a large format interchangeable core, and the core is ordered separately so you can match the PDQ core and keyway to the building's existing key system. Order a Schlage-compatible LFIC core alongside it or the housing arrives unkeyed and unusable.
2) What is the difference between the Schlage LFIC housing and the Best SFIC mortise housings PDQ offers?
Core format, and they are not interchangeable. The I5304 is a large format housing for Schlage-style LFIC cores. PDQ's Best compatible small format housings take SFIC 6-pin or 7-pin cores and come in 1-1/4, 1-3/8 and 1-1/2 inch lengths, including tapered 1-1/2 inch versions. Pick the housing that matches the core format your building already keys to, because a small format core will not seat in a large format housing.
3) If a tenant loses a key, can I rekey the door without pulling the lock off?
That is the reason to use an IC housing. With a core installed in the I5304, a control key pulls the core out and a new core drops in, no disassembly of the lockset and no removing it from the door. For a property manager turning units or responding to a lost key, it is a swap at the door rather than a locksmith visit to rekey a cylinder.
4) I need a rim cylinder for an exit device, not a mortise cylinder. Does PDQ make a matching LFIC version?
The I5304 is the mortise housing. PDQ's interchangeable core range also includes a Schlage compatible LFIC rim housing, which is what a rim exit device needs. Mortise housings thread into a mortise lock body; a rim device takes the rim housing with its tailpiece and back plate, so the two are not substitutes.
5) What finishes does the PDQ I5304 mortise cylinder housing come in?
Seven: 605 bright brass, 606 satin brass, 612 satin bronze, 613E dark oxidized satin bronze, 622 flat black, 625 bright chrome, and 626 satin chrome. Each is its own part number, so a satin chrome unit orders as I5304626. For a building standardized on 626 or 613E trim, the housing can be matched to the existing lock finish.
6) Is the PDQ I5304 suitable for commercial openings or is it a residential cylinder?
Commercial. PDQ lists the I5304 as a commercial door hardware item, intended for mortise lock bodies and exit hardware in buildings keyed on a master key system rather than for residential retrofit.
