🔧 STEP-BY-STEP GUIDE

1️⃣ Open the Door

Open the door so you can easily access the faceplate and cylinder fixing screw. Ensure the door remains stable throughout the process.

2️⃣ Remove the Fixing Screw

Locate the long screw in the middle of the door edge (level with the cylinder) and unscrew it completely.

3️⃣ Turn the Key to Align the Cam

Insert your key into the lock and turn it slightly until the cam aligns — this allows you to slide the cylinder out smoothly.

4️⃣ Slide Out the Old Cylinder

Gently pull the cylinder from the door using the key as leverage. If it’s tight, wiggle slightly while pulling outward.

5️⃣ Fit the New Cylinder

Insert your new cylinder, turn the key to align the cam again, and secure it with the fixing screw. Test both sides to ensure smooth locking and unlocking.

💡 Pro Tip: Always check that your new cylinder is the correct length — it should sit flush with the handle, not stick out.
