Codelocks’ new CL600 Series lever locks are recombinated without removal from the door or disassembly. These mechanical pushbutton locks are constructed with zinc alloy casings, stainless steel buttons and hardened steel clutch components. The stainless steel buttons eliminate problems of button wear associated with user code deciphering.

The weather resistant Codelock CL600 Series locks have field reversible levers to accommodate door handing. The exterior lever is equipped with a conventional 6-pin tumbler “C” keyway lock cylinder. The lock cylinder provides two functions: emergency override and the ability to change the code. The interior lever provides free egress at all times.

Two CL600 Series locks are equipped with the dead latch - the CL610 and CL615. The CL615 has all of the features of the CL610 and the “Passage Mode” function. Entering the correct code and pressing the “P” button enters the lock into the passage mode. To exit the “Passage Mode,” press the “P” and “C” buttons. The Codelocks CL615 lock can be identified by the black dot on the face of the “P” button.

Two rows of pushbuttons are numbered one through zero and letters “X”, “Y”, “P” and “C”. The “X” and “Y” buttons function the same as the number buttons on the CL615 models. The “C” button clears the code chamber. The “C” button is always the first button to be entered in every code.

According to Codelocks, the CL610 lock has more than 8,000 possible code combinations using from one to 13 buttons including the “P” button. The CL615 lock has more than 4,000 possible code combinations using from one to 12 code buttons. Codelocks does not recommend using shorter, one- or two-character codes for most lock applications. Typically codes are four to seven characters long. As an example, a six-character code has more than 1,700 combinations.

There is one important rule when choosing a code: the numbers and letters can each be used only once. For example, the provided CL615 lock has the code C5670X. To enter a code, always press the “C” button first to clear the code chamber. Then the remaining characters of the code are entered. The code does not have to be entered sequentially. For example, once the “C” has been entered, the remainder of the code can be entered as 5670X or 075X6 or in any order. Once all of the characters have been entered, push down on the lever handle to retract the latch.

Important: There is no specific factory default code for the CL600 Series locks. This is because Codelocks has determined that most people do not change the original code.

The code can be changed without disassembling or removing the lock from the door. To change a known or unknown code, the code chamber must be in the “Change Mode” using the lock cylinder in the outside lever. To enter the “Change Mode,” insert and rotate the key counterclockwise approximately 90 degrees until it stops. A provided T-handle code change tool is used to change the buttons to or from non-code and code.

The first step is to place all of the buttons into the non-code position. Once the code chamber is the “Change Mode,” place the code change tool onto a button. Push in very slightly, approximately 1/16”and turn counterclockwise 180 degrees. If the button is not pushed in, the button will not change from coded to non-coded. If the button was coded, the tool will turn freely during the rotation until it stops. If not, the button will not turn.

Repeat the procedure for all of the number buttons and the letter buttons. At this time all of the buttons should be in the non-code position.

Press the “C” button to reset the code chamber. To be certain all of the buttons are in the non-code position, press the lever in order to retract the latch. If the latch retracts, then all of the buttons are in the non-code position.

To program the CL600 Series locks, choose the new combination. Remember: Each character may be used only once. Place the code change tool over the first number or letter button. Push in very slightly, approximately 1/16”and turn clockwise 180 degrees until the button stops rotating. Repeat the procedure for all of the number buttons and the letter buttons in the code. When finished, turn the key to the override position and retract the latch. Depress the lever. A snap will sound and the code buttons will relock. Remove the key.

Important: Test the code with the door open at least three times to be certain the lock was properly programmed.

If the code is forgotten and no override key is available, a temporary fix can be made by decoding the lock. To decode the lock, remove it from the door. Look at the backside of the exterior casing. The position of the tabs on the rear of each button will indicate if the button is coded or non-coded. If the red paint dot on the rear of a button is closer to the middle of the lock case, the button is coded. If the red painted dot is closer to the edge of the lock case, the button is non-coded.

The lock cylinder can be removed without removing the lock from the door. Use a 3/32” hex wrench to remove the lever and cover. Insert the key into the lock cylinder and rotate 90 degrees counterclockwise. Slide the lock cylinder out of the lock. The CL600 Series use a six pin tumbler lock cylinder with a very short driver.

For new installations, Codelocks recommends four cross bore holes; three 3/8” diameter and one 1-3/16” diameter. As an alternative, two 3/8” diameter holes are for the retaining the upper portion of the exterior and interior cases. A single 2-1/8” bottom hole provides sufficient room for the spindle shafts and the one hole for securing the lower portion of the cases. A one-inch diameter edge bore opening is required for the dead latch.

Note: The inside lever must be removed in order to gain access to the lower mounting screw. The three mounting screws require the provided 5/32” hex wrench.

For retrofit applications, install the dead latch. Mount the CL600 Series lock using the bottom mounting screw to secure the exterior and interior casings. Use a level to make sure the casings are vertical. Use the upper screw holes on the interior to locate the holes. Remove the lock, and drill the two upper mounting homes.

Once the door prep has been completed, the CL600 Series lock is mounted onto the door with a provided 5/32” hex wrench. For exterior applications, be certain to install the neoprene seals.

The CL600 Series locks are available for commercial and residential application where the door is 1-3/8” to 1-3/4” thick. The dead latch backset is available in 2-3/4” or 2-3/8”. Available finishes are brushed stainless steel and polished brass with Physical Vapor Deposition (PVD) coatings to provide protection against wear, abuse and the environment.

Codelocks CL600 Series has a limited lifetime warranty.
