Schlage Commercial 48-101 Cut Control Key for Construction Core, Embossed Both Sides

The 48-101 is a cut control key for Schlage interchangeable construction cores. It is the key that pulls the temporary construction core out of the lock so the permanent core can be dropped in once the building is turned over. It does not operate the lock, it removes the core. Non-handed, so the same key works regardless of which way the door swings.

You can. The 48-101 order takes a keying selection, keyed different (the standard), keyed alike if you want multiple keys running the same cut, or none if you are buying a less-cylinder arrangement. There is also an optional key code field, so if your building already runs a known construction core code, enter it and the key comes cut to that code instead of a new random one.

Yes, the 48-101 is stocked as a replacement part for exactly that. Order the version matching your core family (ICA, ICB or ICC) and, if you know the existing construction core code, enter it in the key code field so the replacement matches the cores already installed rather than arriving on a fresh cut.

It is a core removal key, not an operating key. Turning it in a Schlage interchangeable construction core releases the core so it lifts out; it will not retract the latch or unlock the door. If you need day to day access on the opening you still need the operating key that goes with the core itself.

Commercial. The 48-101 belongs to Schlage's commercial line and serves interchangeable construction cores, which are a commercial specification item. Residential Schlage cylinders do not use a removable interchangeable core, so there is nothing for this key to pull on a house lockset.

One per crew that needs to swap cores, and order them keyed alike if you want a single cut to work across the whole job. The keyed alike option on the 48-101 exists for that, several keys, one cut. If different trades or different phases should not share access to the same cores, order keyed different instead so each key stands on its own.

Both faces carry the embossing so the key reads the same whichever way it comes out of a pocket or off a ring. On a jobsite where the general contractor is handing construction keys between trades, that matters, the key gets identified as the control key without anyone having to flip it over and hunt for a stamp.
