Schlage 48-311-GRN – Frequently Asked Questions
1) What is the Schlage 48-311 green construction key actually used for on a job site?
The 48-311 is a cut control key for Schlage small format interchangeable core (SFIC) cylinders during the construction phase. While a building is under construction, the green construction core sits in the lockset so trades can get in on a temporary key. When the job turns over, that key is used to pull the construction core and swap in the permanent core, which retires the construction keys without touching the lock body itself. It is a replacement part, not a lock, and it is non-handed, so the same key works regardless of door swing.
2) Is the Schlage 48-311 a key that opens the door, or does it only remove the core?
It is a control key, so its job is pulling the interchangeable core out of the housing, not throwing the latch. Anyone who needs day to day access during construction carries the operating key cut to the construction core. The 48-311 stays with whoever is responsible for the turnover, typically the GC's superintendent or the locksmith doing the changeover.
3) Will the Schlage 48-311 control key work on any small format interchangeable core lock?
It is a Schlage SFIC control key and it is cut to a specific control section, so it pulls the cores it is keyed to, not every SFIC core in a building. If your cores were supplied under a different keying system or by another manufacturer, the control key from that system is what removes them. Order the control key against the same keying record as the cores it has to service.
4) Does the Schlage 48-311 come in anything other than green?
Two colors are offered on the 48-311 cut control key, green and brown. The color is a visual code so a crew can tell the construction control key apart from the permanent control key on a ring, which matters on a site where several key sets are circulating at once.
5) I lost the control key for my Schlage construction cores. Can I just buy the 48-311 as a replacement?
The 48-311 is sold as a replacement part, so yes, it is the right item to reorder. It has to be cut to the control section of your existing keying system to work on cores already in the doors, so reorder it against the keying record for that job rather than treating it as a stock item that fits anything.
6) Is the Schlage 48-311 control key meant for commercial buildings or houses?
Commercial. Interchangeable core keying and a separate construction phase are how institutional and multi tenant jobs are handled, which is where this key belongs. A single family residence with standard key in knob cylinders has nothing for it to remove.
7) Do I need a different Schlage control key for left hand and right hand doors?
No. The 48-311 is non-handed. Cylinder cores are indifferent to door swing, so one key serves left hand, right hand, and reverse bevel openings across the building.
