This is ideal for homes in Southgate and Whetstone.
SS312 Diamond Sold Secure offers additional attack resistance, often necessary for high-value properties in areas like Cockfosters and Hadley Wood.

On the day of your lock change, we arrive fully prepared to guarantee a swift and efficient process.
We start by measuring the cylinder length from the center screw. Common fits in areas like N14 Southgate and N20 Whetstone are 35/35, while N18 Edmonton and EN5 Barnet often require longer sizes like 45/50. For thicker doors in N21 Oakwood, 50/55 may be necessary.
Next, we source the matching anti-snap cylinder from our van inventory. We remove your old cylinder by taking out the center screw on the door edge and slide the new one in. After securing it with the screw, we test the key turn from both sides under load to confirm everything works perfectly.
Finally, we hand over new keys—typically three—and a registered restricted-key card if applicable.
The entire job usually takes 15-25 minutes, confirming minimal disruption to your day.
