Lockey KOS Add-On Key Override System

With the Lockey KOS, you can use either a metal key or a code to unlock a Lockey 2000 Series keypad lock.

It is compatible with the following Lockey keyless, keypad locks:
- 2200
- 2210/2210DC
- 2830/2830DC
- 2835/2835DC

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.

This product comes with a small trim plate that goes between the KOS and the lock. However, it does include one to go between the KOS and the door or gate.
