• Strike Plate: This is a metal plate affixed to the door frame, which the lock bolt protects into when the door is closed.
• Escutcheon Plate: The decorative plate that usually surrounds the door handle, concealing the screws and providing the door a completed look.
• Cylinder: In locking systems, the cylinder is where a secret is inserted to turn and secure or open the door.

• Clean Handles and Locks: Use a microfiber fabric to clean down door handles regularly. Dust and dirt can build up in the mechanism, triggering it to jam.
• Oil Moving Parts: Every six months, use a silicone-based lube to the moving parts of the mechanism to ensure smooth operation. Prevent utilizing grease, which can attract dirt.
• Inspect for Tightness: Ensure screws and bolts are tight. Loose handles can trigger wear on internal components and might need replacement sooner than expected.
• Examine for Wear and Tear: Regularly check handles for indications of wear, such as scratches, dents, or rust. Changing damaged parts promptly can prevent more significant issues down the line.
• Test Locks: If the door handle functions a locking mechanism, check that the lock operates properly. If it jams regularly, it may need to be oiled or replaced.
