The 35-269 is an uncut control key blank for Schlage Everest 29 full size interchangeable core cylinders. A control key is what pulls the core out of the housing so you can swap cores without disassembling the lock; it does not operate the latch or bolt. It ships as a blank, so a locksmith cuts it to your control section before it will remove anything.

No. The 35-269 blank is cut for Everest 29 keyway sections (S123, S125, S145). Everest keys carry the undercut check pin feature that Schlage Classic keyways do not use, so the blank belongs to Everest 29 cores only. If your building is on Classic or Primus, you need a control key blank in that family instead.

The 35-269 blank is embossed "Do Not Duplicate", which is a policy marking, not a physical control. What actually restricts copying on this key is the Everest 29 keyway itself, since those blanks are distributed through Schlage's controlled channel. For a facility that wants control keys accounted for, the embossing plus the restricted section is the combination that matters.

It arrives as a blank, uncut. You or your locksmith cuts the control bitting for your system on a key machine. There is no factory cutting, no pinning, and no core included, so budget for the cutting step before the key will pull a core.

Keys only. The 35-269 is a blank key, nothing else in the box. If you still need cores, ZenSupply carries small format IC cores such as the GMS 6-pin and 7-pin SFIC cores, sold un-combinated with keys, pins, springs and caps not included. Note those are small format, a different platform from Schlage Everest 29 full size cores, so the 35-269 blank is not the control key for them.

Two different jobs. The operating key throws the latch or bolt for daily use. The control key, which is what the 35-269 blank becomes once cut, retracts the core's control lug so the core lifts out of the housing. On a property where you rekey by swapping cores, the control key is the one you keep locked up, because whoever holds it can remove every core it is cut for.

Yes, as long as the cores are Everest 29 full size in one of the S123, S125 or S145 sections. The control key is cut to the core, not to the housing, so the same cut key pulls that core out of a mortise housing, a rim housing or a knob or lever. That is what makes one control key practical across a mixed building.

Fewer than you think. One cut control key per person who is authorized to pull cores, plus one spare held in the office, covers most properties. Control keys are the highest privilege key in an IC system, so ordering a stack of blanks and cutting them all defeats the point of running interchangeable cores in the first place.
