Five Reasons People Change Locks Across W London
Changing locks is a common necessity across West London. We often find ourselves needing to secure our homes for various reasons.
Moving into a new tenancy means there might be keys floating with previous tenants or contractors, so swapping the cylinder on the same day is wise. After an incident or attempted entry, insurers like Aviva and AXA require us to upgrade to BS3621 or 3-Star Diamond locks, especially in high-value areas like Chiswick and Ealing.
If there's been a staff or housekeeper change, replacing every external door cylinder is a precaution we can't overlook. Misplaced or stolen keys around stations like Ealing Broadway prompt quick cylinder swaps, which are more cost-effective than a full rekey.
Finally, insurance renewals often flag old locks that don't meet current standards, a frequent issue in Greenford and Northolt.

Step by Step Through a Lock Change
On the day of the lock change, we start by evaluating your door and measuring the cylinder length from each side of the center screw. Common sizes like 35/35, 40/35, or 40/40 mm are often found in UB6 Greenford and UB5 Northolt, while longer 45/50 mm or 50/55 mm cylinders suit thicker doors in TW8 Brentford and Southall.
Next, we source a matching anti-snap cylinder from our van's inventory. We remove the old cylinder using the center screw on the door edge, slide in the new one, and secure it.
Then, we test the key turn from both sides to guarantee smooth operation.
Finally, we hand over three new keys along with a registered restricted-key card if needed. We file the old cylinder for your records.
The entire process takes about 15-25 minutes, though it may be longer for conservation-sensitive period doors.
