On the day of your lock change, we guarantee everything runs smoothly and efficiently. We start by measuring the cylinder length from the center screw to ascertain a perfect fit. Common sizes in Old Street include 35/35, 40/35, or 40/40 mm for Georgian retrofits, and 45/50 mm for modern composite doors.
Next, we source a matching anti-snap cylinder from our van, confirming it meets insurance specifications. We carefully remove the old cylinder via the center screw on the door edge, then slide in the new cylinder.
Securing it in place, we test the key turn from both sides to verify smooth operation. Once satisfied, we hand over the new keys—usually three with anti-snap cylinders—and file the old cylinder for your records.
The entire process takes just 15 to 25 minutes, providing your with minimal disruption.

While maintaining security in our homes is vital, replacing a multipoint strip on UPVC and composite doors can seem intimidating. But with the right approach, it doesn't have to be.
First, let's assess the situation. Is the door not locking smoothly, or is there damage to the strip? These are signs it might be time for a replacement.
We'll start by removing the door handle and any visible screws securing the strip. Carefully slide the old strip out, noting its alignment. This is essential for fitting the new one correctly.
When selecting a new multipoint strip, verify it's compatible with your door. Popular choices include Mila Master and Yale Lockmaster, known for reliability.
Once aligned, secure the new strip with screws, reattach the handle, and test the lock.
With just a little effort, we can enhance our home's security and enjoy.

Phone-quote, no callout fee. BS3621 + 3-Star Diamond compliant locks fitted same day across Old Street, Shoreditch, Hoxton, Clerkenwell and the wider EC1/E1 corridor.
Understanding insurance compliance for locks can seem challenging, but it's essential for ensuring our homes are secure and meet policy requirements.
We need to focus on two key standards: BS3621 and the 3-Star Kitemark. BS3621 is vital for mortice locks, ensuring they meet rigorous security criteria. Locks like the Union 2134 and Yale PM562 are excellent examples of BS3621-rated options.
For euro cylinders, the 3-Star Kitemark offers top-level security against snapping, a common burglary method.
Products like the Ultion and Yale Platinum cylinders are designed to this standard, providing robust protection.

From 23 Henriques St, London E1 1NB we cover Old Street and the surrounding EC1/E1 corridor — Shoreditch, Hoxton, Clerkenwell, Islington and Angel — with rapid response.
Let's shift our focus from insurance compliance to what we can expect regarding cost and time when installing high-security locks.
Our experience shows that prices can vary depending on the type of lock and installation complexity. For instance, a Sold Secure Diamond anti-snap cylinder might range quoted on the call to (quoted on the call), while a BS3621-rated mortice lock could be between (quoted on the call) and (quoted on the call).
Time is another critical factor. Typically, an experienced locksmith can replace a standard cylinder in about 30 minutes. However, fitting a new mortice lock might take up to an hour or more, depending on the door's material and existing cutouts.
We should also consider the potential for additional charges, such as emergency call-out fees or supplementary security features.
It's always wise to discuss these details upfront with our locksmith. This way, we guarantee a smooth, transparent process, both cost-effective and time-efficient.
