Lockey KOS Add-On Key Override System

The Lockey KOS (Key Override System) is a product that makes is possible to unlock a Lockey 2000 Series lock with either a metal key or a code. It is installed between a lock and a door or gate. The KOS can be used in several different ways:

with a single-sided Lockey 2000 Series lock (like 2210, 2200, 2500, 2830, 2835, etc.) that has a keypad on only 1 side
with a double-sided Lockey 2000 Series lock (like a 2210DC, 2830DC, 2835DC, etc.) that has a keypad on BOTH sides.
or on both sides of the door, as long as the overall thickness of the locks plus the gate or door plus the KOSs is under 5 inches. This is because the extension kit will only work on doors or gates that are up to 5” thick and each KOS is approximately ½” thick.

KOS must be purchased with the Lockey Thick Door Kit (Extension Kit) for the lock you will be using, which is sold separately.

Usage Information:

You will ALWAYS need a Lockey Thick Door Kit (Extension Kit) with a KOS because each KOS adds an additional 5/8" of thickness. Be sure to account for that when you measure your thickness. Also, note that an extension kit only lets you go up to a maximum of 5" inches total for your door plus any KOS(s).

The KOS is compatible with the following Lockey keyless, keypad locks:

2200
2210/2210DC
2830/2830DC
2835/2835DC
285P Keyless Panic Trim

The KOS is NOT compatible with Lockey 2900 Series locks that are installed on narrow stile doors. The KOS is too wide for a narrow stile and will extend over the edge of the door frame.

This product comes with a small trim plate that goes between the KOS and the lock. However, it does not include one to go between the KOS and the door or gate.

The KOS has a Schlage C 6 pin keyway. It cannot be re-keyed because the key cylinder is attached to the spindle and cannot be removed for re-pinning. However, you can purchase KOS's that are already keyed alike and then re-key any existing locks to match them as long as they all have the same keyway. See Lockey Key-Alike Service
