Mortise cylinders have always been at the foundation of Medeco's product line. In fact, 10 Series mortise cylinders were the first to roll off the assembly line when Medeco opened its doors and started production in 1968. Although the overall mortise cylinder design has seen very little change...

Step 6. Insert Key into Plug. (Figure 27 & 28) Before we can insert the plug back into the shell, a key will need to be inserted into the plug. With no key in the plug, the blocking tabs of the slider are blocking the sidebar from being pushed in. In this state, the plug will not be able to be inserted.
While inserting the key, hold your finger over the slider to prevent it from popping out. After the key is fully inserted into the plug, push in on the sidebar. If the sidebar does not push in, you may be using a key with the wrong side bitting, you may have installed the wrong slider, or the sidebar springs may have tipped.
Step 7. Insert the Plug into the Shell. In order to insert the plug into the shell, push the key in all the way while also pushing in on the sidebar. This process is made easier by standing the shell upright while inserting the plug from the top rather than the side.
Step 8. Install Cam, Cam Washer, and Cam Screws. Once the plug has been fully inserted into the plug, the cam, the cam washer and the cam screws can be reinstalled. The back of the cam should be flush with the back of the shell and the cam washer hole should be in line with the keyway (not covering it).
On five-pin Medeco3 mortise cylinders, the cam screw located on the left side (looking from the back of the cylinder) will be shorter than the one on the right. The left cam screw is shorter so that it will not interfere with the slider mechanism. The shorter cam screw should be installed in the 7 o'clock position on the cam washer.
The Medeco3 mortise cylinder is now completely reassembled and is ready to be pinned. Part numbers for the cam washer and the cam screws are shown in Figures 31, 32, & 33.
PINNING MEDECO3 MORTISE
Medeco3 mortise cylinders are pinned in much of the same manner as standard pin tumbler cylinders; however, they are top-loaded and do not require a plug follower. Medeco3 mortise cylinders are pinned from bow to tip (cylinder face to cam).
Keep the following information in mind when pinning Medeco3 mortise cylinders:
· Mushroom top pins should be inserted with the cap pointing down toward the bottom pin.
· If possible, two mushroom top pins should be used in each cylinder. The mushroom pins provide additional pick resistance.
· Two hardened steel top pins should be used in each cylinder. These pins provide additional drill resistance.
Pinning Tools Required:
· Pinning kit – K-5001 (Large Pinning Kit), K-5005 (Small Pinning Kit)
· Cylinder holding fixture (optional) – CP-282451
· Medeco screwdriver or 5/64" Allen wrench
· Key decoder – 94-0032
· Medeco KeyLube 2.0 – PX-KYLUB2-03
· Tweezers (optional)
Step 1. Determine the pinning of the cylinder. This can be accomplished by decoding a key, decoding a blind code, or referencing the pinning from a bitting list.
Step 2. Load the cylinder into the holding fixture.
Step 3. Secure the cylinder in the holding fixture by tightening the cylinder set screw located on the side of the holding fixture.
Step 4. Insert the key that the cylinder is to be pinned to. You will use this key to test the cylinder pinning as each pin chamber is loaded.
Step 5. Select the proper bottom pin from your keying chart or bitting list and load it into the cylinder. (Figure 37) Place the pin over the pin chamber with the locator tab on the pin directly over the locator tab slot in the pin chamber hole. Do not force the pin into the pin chamber. If the locator tab is not aligned with the locator tab slot, rotate the pin until both are aligned. Test the key after each bottom pin is inserted.
If the key does not rotate the plug, the pin may not be fully seated on the cut of the key. Lightly press down on the pin to seat it on the key.
CAUTION: Only push down on the pin if you are sure that the locator tab on the pin is aligned with the locator tab slot in the pin chamber hole.
If the key still does not turn, it is likely that the improper pin was used. Extract the pin and use the correct one. Check your pinning kit and the pinning information.
Step 6. Load the corresponding top pin. The required top pin number will match the corresponding bottom pin number. This is necessary to maintain a consistent pin stack height within the pin chamber. An example of this would be a number 5 length bottom pin with a number 5 driver on top.
