Lockey KOS Add-On Key Override System

The Lockey KOS lets you use a metal key in addition to a combination to unlock a Lockey 2000 Series keypad lock.

It will work with either a new lock or one that has already been installed.
This product does NOT alter the Manufacturer's Life-Time Mechanical Warranty, unlike a built-in key override option that is in the round flat knob on the outside lock body. (This option is not recommended and is being phased out.)
IMPORTANT: This product is NOT compatible with Lockey 2900 Series locks. It is too wide to fit on a narrow stile door and the product will extend over the edge of the door frame slightly.
IMPORTANT: If you want to use the KOS with a double-sided lock, you will need a Lockey Thick Door Kit (Extension Kit). Otherwise, the screws, hex bolts, and spindles will not be long enough to reach all the way through.

Usage Information

This product is designed to be installed between the lock and the door/gate. It can be used:

with a single-sided Lockey 2000 Series lock (like a 2210, 2835, etc.) that has a keypad on only 1 side
with a double-sided Lockey 2000 Series lock (like a 2210DC, 2835DC, etc.) that has a keypad on BOTH sides.

The KOS is 5/8" thick, so if you are using a double-sided lock, you will also need to purchase a Lockey Thick Door Kit (Extension Kit) if the thickness of your door plus the thickness of the KOS is more than the maximum specified for your lock. This is generally 2" but be sure to check the specs on the lock detail page to be sure. Otherwise, the screws, hex bolts, and spindles will not be long enough to reach all the way through.

This product has a Schlage key cylinder and comes with 3 metal keys. If you want these keyed alike, be sure to add Lockey Key-Alike Service to your order.
