    Hired them to change the old locks of the house because we wanted to feel safe. Had fitted only British Standard strong locks in a professional manner.

    Best 24 hour Locksmith in West End. Would’ve been stuck inside my restaurant without them. I appreciate how prompt they were, in 25 minutes after my call at my location in WC1.

    I locked myself out of the house and these guys turned up extremely quick at my doorstep. They opened and changed my Banham locks fast, the entire job took them around half an hour. Would recommend.

Why a High Security Lock Upgrade Is Worth Doing

A working lock isn’t always a secure one. Plenty of standard locks will open up with a bit of force, or a snapped cylinder, or even a bent key. Criminals know what they’re doing, and most old locks just don’t stand a chance.

A proper high security door lock upgrade protects you from:

  • Forced entry and door attacks

  • Drilling and snapping of the cylinder

  • Unauthorised key duplication

  • General wear and tear that makes locks weak over time

The difference between a standard lock and a British Standard lock is night and day. A good lock doesn’t just “lock”, it resists. It holds firm when someone tries their luck. That’s what you’re paying for.

If you’re unsure whether your current locks meet BS3621 standards, we can check that for you during the visit, or you can learn a bit more about it on our BS3621 lock page.

Alternatively, give us a call, we’re professional locksmiths who enjoy giving advice to our customers.

Types of High Security Locks and Standards

When you go for a high security door lock upgrade, you’re not just getting a shinier lock. You’re upgrading to something that meets strict British Standard (BS) specifications — the kind insurers love to see.

As expert locksmiths, we fit and supply:

  • BS3621 Mortice Locks for wooden external doors (BS3621 Lock)

  • High security cylinders for uPVC and composite doors

  • Banham lock replacement options for classic London properties

  • Ingersoll lock upgrades for heritage and commercial buildings

Each of these locks meets or exceeds insurance requirements, has intuitive design features and police-approved standards. That means you’re not just more secure — you’re also compliant.

If you want to go one step further, we can fit Mul-T-Lock systems with restricted key profiles.

They’re popular for people who want tighter control over who can get a key cut. All locks are properly tested and marked to British Standard, that’s what insurers like to see, and frankly, it’s what you should want on your door.

How We Handle a Lock Upgrade

From arrival to installation, we keep it simple and tidy. No drama. All for your convenience.

  • First things first, if it can be repaired, we will repair it. We don’t want our customers making unnecessary purchases.

  • We check your doors, type, condition, frame, hinges, and any old locks.

  • We show you options, what fits/what’s suitable for you, what’s approved, what’ll give the best protection.

  • We install it, properly aligned, secured, and tested.

  • We test and explain, you’ll see how it works and how to keep it running smooth.

Most high security internal or external door lock upgrades and installations are done same-day. If you call early, we’ll usually get it done before the end of business hours. We don’t leave you hanging around with a half-finished job.

 

What “British Standard” Really Means

A British Standard lock isn’t marketing talk, it’s one of the highest levels of security, tested against drilling, snapping, picking, and forced entry. If your insurance says you need BS3621 locks, they’re talking about this.

These locks include design features such as:

  • A 5-lever mortice or equivalent mechanism

  • Hardened plates and anti-drill pins

  • A solid deadbolt that locks fully into the frame

  • Mortice locks for one of the highest levels of security and peace of mind

  • Keys that can’t be duplicated without your authorisation

If your locks don’t show a BS mark, you might not be fully covered under your insurance policy. It’s worth checking, especially if your doors haven’t been looked at in years.

What Makes a Lock “High Security”

There’s a big difference between a lock that looks strong and one that actually is.

Here’s what goes into a proper high security lock:

  • Reinforced mortice lock body or external cylinder

  • Hardened steel parts to resist drilling and snapping

  • Anti-pick mechanisms

  • Controlled key systems (no random copies made without permission)

  • Solid deadbolts and latch bolts that actually grip into the frame

We’ll also check your door frame, because even the best, high security lock won’t help if the frame’s weak. The whole setup needs to work as one.

Banham and Ingersoll Lock Upgrades

We do a range of Banham and Ingersoll lock work across London. They’re quality brands and well-trusted, but even good locks need attention over time. Cylinders wear down, keys stop turning smoothly, or the lock doesn’t quite meet the latest British Standard.

You’ll still have the same reliable style, but with modern internal components that meet today’s standards.

Every Banham lock replacement and Ingersoll upgrade is done properly, following manufacturer specs, not guesswork.

When to Install New Locks?

One of the biggest prompts we usually see for our clients is that they have suffered a burglary or break-in, such an act of unauthorized entry and a physical attack on their property, is a real wake-up call.

As unfortunate as this is, this should not be the trigger. Let’s make preventative maintenance a thing and change your locks before you get broken into.

The new, changed locks will keep the burglars out, stand up to physical attacks, be an additional security layer and prevent unauthorized entry.

High Security for Businesses and Homeowners

We handle both residential and commercial properties. Doesn’t matter if it’s a flat, house, small shop, or large office — we’ll recommend locks that suit the job.

We can install:

  • Master key systems for controlled access

  • BS locks on exterior and staff entry doors

  • High security cylinders for shutters and gates

  • Access control upgrades for shared or managed buildings

Whether you’re protecting stock, data, equipment, or your home, our high security locks give you long-term protection and better compliance.

If you’re unsure, we’ll talk you through the door hardware options and give honest advice.

FAQs: High Security Door Lock Upgrade

Do you fit mortice locks?

Yes, as part of our professional high security door lock upgrade services, we will fit your mortice locks for you.

Can you fit Banham or Ingersoll locks?

Yes, we do both, Banham lock replacements and Ingersoll upgrades are part of our standard work.

Will you match my new locks to my existing keys?

In some cases, yes. If not, we can set up a master key system so you’ve got one key for multiple doors.

Do you fit locks on the same day?

Most times, yes. We carry plenty of high-security locks in stock and can usually do it all in one visit.

Do you have advice on unauthorized key duplication for landlords?

If you have a tenant leave, and you are unsure whether they carried out any unauthorized key duplication, its best to get new keys rather than the same keys.
