Sargent 6251CMK – Frequently Asked Questions

1) What is a Sargent 6251CMK construction master key actually used for on a jobsite?
The 6251CMK is a temporary construction master key for Sargent 64 series removable core cylinders. During the build, contractors and trades operate the openings on the construction keying. When the building turns over, the removable core comes out and the permanent core drops in, so the construction key stops working without changing a single cylinder. That is the whole point of the removable core setup: the transition to permanent keying happens without cylinder replacement.
2) Which Sargent cylinder series does the 6251CMK construction master key work with?
It works with Sargent 64-, 11-64-, DG1-64, DG2-64 and DG3-64 series cylinders. If the cores on your job are one of those, this key covers them. Anything outside that group is a different key.
3) Will the Sargent 6251CMK work on 7-pin cylinders?
No. The 6251CMK is a 6-pin key, cut for 6-pin 64 series cores. A 7-pin core takes a 7-pin construction master key. Check the pin count on the cores your keying schedule specifies before ordering, because the two are not interchangeable.
4) Does the Sargent construction master key operate mortise and rim cylinders, or only one type?
Both, plus component cylinders and Large Format Interchangeable Core. So a mixed job with mortise locks on the offices, rim cylinders on the exit devices and LFIC elsewhere can run on one construction key, as long as every one of those cores is in the 64 series family.
5) Do I need to replace the cores when the building is handed over from the contractor?
No core replacement is needed. With the 64 series removable core design, you pull the temporary core with a control key and seat the permanent core in the same housing. The lock, the trim and the prep all stay put, and the construction master key is dead the moment the temporary cores come out.
6) Can I just order a Sargent 6251CMK construction master key, or is it restricted?
It moves through authorized distribution with geographical protection. That is deliberate on a key that opens every temporary core on a construction site, and it is what keeps duplicates from circulating outside the people who are supposed to hold them.
7) Is the Sargent 6251CMK a key blank I need cut, or is it ready to use?
It ships as a finished construction master key, not a blank. It is a replacement part for the 64 series construction keying system, so it is ordered to match a keying setup you already have rather than cut locally.
8) Is the Sargent 6251CMK meant for commercial jobs or residential?
Commercial. It is built around commercial construction keying: schools, hospitals, multi-tenant residential build-outs, government and industrial projects, plus renovation work where cores are being changed over in phases.
