INSTALLING Schlage CO Series Offline Locks

Schlage CO Series locks are available in three models, the CO-100, CO-200 and CO-250 locks.


The inside lever and spring cage are then screwed into this plate. To operate the lock mechanism, there is a spindle that extends from the retractor mechanism, a spring and a die cast hub that slides into the inside lever assembly. This hub must be positioned with the two tabs vertical in order to position the lever horizontal. The retractor hub has different teeth to accommodate the spindle in order to position the hub correctly. Check to be certain the inside lever retracts the latchbolt when rotated clockwise or counterclockwise.

The next step is to install the inside escutcheon onto the inside face of the door using the two supplied screws. Once attached, run the DPS (if installed) wiring and the ribbon cable into the escutcheon. Make the three connections, the ribbon cable, DPS wiring and connect the battery holder wires. Once attached, properly position the excess wire and secure the battery holder using the provided strap and two screws.

Secure the cover onto the escutcheon. Test the mechanical operation of the lock. The next series of steps are to program the lock.

The CO-200 and 250 Series locks can be used in Construction Access Mode that allows all of the locks to be first manually programmed for construction access without the need to utilize the HHD. Even if construction mode is utilized, the locks can be reprogrammed for the end users’ specific applications.

One minor issue occurred during the installation of the CO lock. There was an initial problem getting the HHD to recognize that it was connected to the lock. We discovered that one of the batteries had come loose from the holder and while the lock could be manually programmed and operated, the voltage drop was enough to prevent the HHD from linking with the CO lock. Re-installing the battery solved the issue and the HHD connected to the CO lock. Note: When troubleshooting, always check the batteries first.

Manual programming the CO-200 at the lock includes single or dual credential programming with normal use, toggle, freeze and pass-through. The PIN can be a three- to six-digit code.

The Schlage button has two bicolor LEDs, one on the left and one on the right. All locks have a default programming code of 97531*. All locks have a default normal use code of 13579#. The default programming codes are removed once the user creates unique manual programming and enters normal use credentials or by programming the lock using management software.

To reset the CO Series lock to factory defaults:

Insert the mechanical override key into the lock cylinder.

Press and hold the Schlage button until the lock beeps twice and the button emits two green blinks.

Release the Schlage button.

Rotate the key within ten seconds and continue to hold the key until the lock beeps twice and the button emits two green blinks.

The Schlage button will emit a green light for one second and a one second beep will sound confirming the lock has been reset to the factory default.

The CO lock battery life for the 4 AA batteries is up to two years or approximately 73,000 operations. Low battery warnings start to occur when approximately 500 operations are left in the battery life. If the main AA batteries are low, the left light flashes red and the right light flashes red for low lithium coin cell.

If the batteries completely discharge, then the mechanical key is used to gain access to replace the batteries. The CO lock is equipped with non-volatile memory to insure against loss of data.

The CO Series locks limited warranty is one year.
