Banham locks come at a premium for a reason, so you’ll know that if you’ve already got Banham locks on your front door, you’re working with one of the strongest setups used in London homes.
If you’re not Banham savvy, you might ask why? Well… They’re solid, heavy, reliable and very much the first choice for properties around Kensington, Chelsea, Belgravia, Mayfair and Westminster.
But, and here is the key, even a premium lock eventually needs attention, keys go missing, cylinders wear down, finishes fade, or you simply want something newer. When (not if) any of that happens, a proper Banham lock change is the way to go.

Here at Mayfair Locksmith London, we are proud to work with Banham locks constantly, and are pleased to be able to cover everything from simple cylinder swaps to full lock replacements, and even L2000 upgrades.
But, because Banham door locks have their own way of behaving, you will want (if not need) a locksmith who actually knows the brand rather than someone guessing with generic tools.
All of our Banham lock work is completed to the highest standard, that’s our guarantee.
Banham locks are popular in London, and for good reason, but, it isn’t just because they’re available in a range of designer finishes…
They’re popular because if you have a Banham cylinder on your door, the chances are you’ll have peace of mind in the knowledge that you’ve done your best at ensuring the safety of your home through your front door lock install.
So, why Banham locks for residential (and commercial) properties? Well, the build quality is higher, the internal parts are stronger, and the finishes look clean on older and newer doors alike.
But, most importantly, the key registration system gives homeowners complete control. That means no unauthorised copies, no surprises when you move in, and no awkward “someone else might still have a key” situations.
The good news? We replace and install brand new Banham locks in satin chrome, polished chrome, satin brass and polished brass, depending on what suits the property.
We’ve seen it all… Some customers want a new cylinder but keep the same finish. Others want everything updated to match a renovated door. We supply the full range so the door looks intentional rather than patched together.
A Banham lock can also get tired after decades of use. The cylinder becomes stiff, the finish dulls, or the latch stops sitting flush. Some customers also choose a Banham L2000 upgrade because it’s one of the most recognisable high-security nightlatches in the range, aside from perhaps the BS3621 lock.
As professional locksmiths, we work with the complete range of Banham locks. We talk through the options first. If the existing lock body is fine, there’s no point replacing the entire mechanism — a new cylinder or matching latch is usually enough. But if the body is worn or the door has been repaired over the years, a fresh installation and high security lock upgrade make more sense.
We’ve handled thousands of Banham installations and replacements around London. That means we already know which models fit which doors, which finishes work best, how to align the bolt so it meets the keep perfectly, and how to open a stuck Banham lock without causing damage. More than that, we can also assist you with a door opening if your key is missing and you have no way in.
We also work on properties where Banham security is used across more than just the main door: gates, grilles, shutters, windows, and older fire burglar alarms linked to older setups.
Banham locks rarely fail without warning, but when they do, they tend to seize completely. If the bolt refuses to move, the cylinder spins, or the latch sticks halfway, forcing it usually makes things worse.
We offer fast emergency locksmith help for stuck Banham locks across London. Whether it is for your house or your office security.
We open the door cleanly, repair or replace the parts that have failed, and make sure the door secures properly before leaving. Because Banham bolts are strong, they need the right technique, not brute force.
If you’ve lost your keys, someone else has access, or you’re dealing with a jammed nightlatch, we can fit a new lock or fresh cylinder on the spot.
