Installation Guide
The Tesa Assa Abloy Series 2030 Mortice Lock is designed for wooden doors. Ensure the door thickness and existing mortice cut-out are compatible with the lock's dimensions (Entrada 70 mm for this model).
Tools Required:
- Drill
- Wood chisels
- Screwdriver (Phillips head)
- Measuring tape and pencil
- Hammer
Installation Steps:
- Prepare the Door: If not already present, mark and cut the mortice pocket in the door edge according to the lock body dimensions. Ensure the backset (Entrada) of 70 mm is accurately measured from the door edge to the center of the spindle hole.
- Install the Lock Body: Insert the mortice lock body into the prepared pocket in the door edge. Secure it with the provided screws through the faceplate.
- Install the Spindle and Handles (not included): Insert the spindle through the square hole in the lock body. Attach the door handles (not supplied) to the spindle, ensuring they operate the latch bolt smoothly.
- Install the Cylinder: Insert the Euro profile cylinder into the designated opening in the lock body. Secure the cylinder with the long retaining screw through the door edge, passing through the lock body and into the cylinder.
- Test Operation: Before installing the strike plate, test the lock's operation.
- Turn the key to ensure the deadbolt extends and retracts smoothly (2 turns for full extension).
- Operate the handles to ensure the latch bolt retracts freely.
- Install the Strike Plate: Close the door and mark the position of the latch and deadbolt on the door frame. Chisel out recesses for the latch and deadbolt, and then secure the strike plate to the door frame with screws. Ensure the latch and deadbolt engage smoothly without binding.

Operating Instructions
Locking and Unlocking with Key:
- To Lock: Insert the key into the cylinder and turn it clockwise. The deadbolt will extend. For full security, turn the key two complete turns until the deadbolt is fully extended. Remove the key.
- To Unlock: Insert the key into the cylinder and turn it counter-clockwise. The deadbolt will retract. Turn the key until the deadbolt is fully retracted. Remove the key.
Operating the Latch Bolt:
- The latch bolt is operated by the door handles (not included). Simply depress the handle to retract the latch bolt and open the door. Release the handle to allow the latch bolt to extend and secure the door in the closed position.
- The cylinder also actuates the lever and the pusher, allowing for entry function with the key.
Maintenance
Regular maintenance ensures the longevity and smooth operation of your Tesa Assa Abloy Mortice Lock.
- Cleaning: Wipe the visible parts of the lock (faceplate, cylinder, keys) with a soft, damp cloth. Avoid abrasive cleaners or solvents, as they can damage the finish.
- Lubrication: Periodically (e.g., once a year), apply a small amount of graphite powder or a specialized lock lubricant into the keyway of the cylinder. Do not use oil-based lubricants, as they can attract dirt and cause clogging.
- Inspection: Check all screws and fasteners periodically to ensure they are tight. If any part feels loose or worn, tighten or replace it as necessary.
- Key Care: Do not use bent or damaged keys, as this can damage the cylinder mechanism.
