🔧 STEP-BY-STEP GUIDE

1️⃣ Remove the Door Handle & Cylinder

Unscrew the handle and pull out the euro cylinder lock. Keep all screws safe for reassembly.

2️⃣ Open the Door Fully

Lay the door flat (if possible) or open it wide to access the full locking strip along the edge.

3️⃣ Remove the Old Lock Strip

Unscrew all fixing points along the full length of the metal strip and gently pull the mechanism out of the slot.

4️⃣ Measure the Backset & Lock Length

Measure the backset (distance from door edge to spindle) and full length of the mechanism. Match these when ordering your new lock.

5️⃣ Fit the New Lock Mechanism

Slide the new multipoint lock into place and secure it with screws. Reinstall the euro cylinder and handle, then test all locking points for smooth engagement.

💡 Pro Tip: Always lubricate the new mechanism with silicone spray to reduce friction and extend lifespan.
