The Lockey 2835DC uses removable stainless steel tumblers to set the operating code. The blue tipped tumblers are the no-code tumblers. The red tipped ones are the code tumblers. Four code tumblers are pre-installed in each lock. Up to six provided code tumblers can be used in the combination chambers.
One blue or red tumbler is placed into the combination chamber directly beneath 1-0 and “X” and “Z” push buttons. Because the 2835DC lock has passage function, the “Y” combination chamber must be equipped with the non-color tumbler. The “C” combination chamber tumbler must never be removed.
Changing the Code
The lock assembly must be removed from the door.
Unscrew the four red anodized screws from the rear of the lock. Be careful, as the numbered plate is spring loaded as the springs place pressure on the tumblers.
Lift off the plate and set aside. The springs are attached to the bottom of the plate.
To remove the code or no-code tumblers necessary to change the code, press the “C” button and lift out the tumblers to be changed using the provided tweezers. With the “C” button pressed, insert the code and no-code tumbler to set the new code. Release the “C” button. The tumblers cannot be removed or installed if the “C” button is not depressed.
Once the combination has been changed, place the plate on the lock assembly and insert the four red anodized screws. Snug the screws. With the lock assembly in your hand, test the code several times. If the lever handle can rotate, the code is correct. Enter the code and press the letter “Y” button to see if the lock assembly goes into passage mode. Press the letters “Y” and “C” to exit passage mode. When satisfied with the operation, secure the four red anodized screws.
Install the lock assembly onto the door. The 2835 lever handle lock with passage function is available in antique brass, bright brass, satin chrome, satin nickel, jet black, white, bright chrome, oil rubbed bronze and a saltwater resistant marine grade finish. Teflon coated finish that is resistant to saltwater corrosion.
