Door Lock Not Working

Almost without fail, you can guarantee that when a door suddenly refuses to behave, it usually happens at the worst possible moment or the most inconvenient time. The key turns halfway and stops. The handle drops, but the door will not open. Or everything feels fine until you try to lock up and realise the door will not secure at all.

Door Locks That Suddenly Stop Doing Their Job

Luckily, most door locks give warning signs before they fail. The trick is to recognise the warning signs and get ahead of them before they become a real issue. The key starts to feel tight. The latch does not retract fully. You need to lift the handle harder than usual. These are early indicators that something in the locking system is wearing out or falling out of alignment.

Ignoring these signs often leads to broken door locks, lockouts, or emergency situations later on. Also, in the past years, London’s and Richmond’s climate has caused doors to expand in summer heat and contract during winter. These conditions lead to potential misalignment, and here we can also assist you.

Door Lock Repairs When the Mechanism Is Still Salvageable

Luckily, not every fault requires a new lock and quite often, door lock repairs are the most sensible solution. That is why we always try to repair a lock before recommending a full-blown replacement. Its easier, quicker, and more cost-effective. 
We inspect the full locking mechanism before recommending anything. That includes the cylinder, latch, internal components, locking points, strike plate, and how the door sits in the frame. If the issue is caused by misalignment, worn springs, or a minor internal failure, a repair restores full function without replacing the entire lock.
This approach is common on mortice locks, night latches, and some UPVC door systems. It keeps costs under control and avoids unnecessary disruption.

Broken Door Locks That Need Immediate Attention

However hard we may try, the simple fact is that some failures cannot be repaired safely. Broken locks, snapped internal components, or cylinders damaged by forced entry fall into this category, or when a lock has failed structurally, continuing to use it risks a full lockout or security breach. 

If repairing the lock is simply not possible, and leaving it as it is would represent a major security risk, then a door lock replacement is the only viable option. Of course, we will full explain the reasoning behind this to you, and then we will make our recommendation on how best to proceed.

Door Lock Replacement When Security Is Compromised

There are situations where replacing the lock is not optional, including lost keys, burglary damage, or repeated lock failures; all fall into this category.

In each of these scenarios, a new lock not only restores peace of mind but also removes uncertainty. We install locks that suit the door, the property, and how it is used. That might be a like-for-like replacement, or an upgrade to a more secure option (your choice, of course).

Our door lock replacement work covers wooden doors, composite doors, UPVC doors, and commercial premises, and where appropriate, we also install smart locks and access control systems, but only if they genuinely suit the property.

Emergency Door Repairs in Richmond

But some problems go beyond the lock itself. Door frames split. Hinges fail. Strike plates loosen. When that happens, even a new lock will struggle.
So, in these situations, emergency door repairs are often required after break-ins or forced entry attempts. We secure the door first, then address the structural issue so the lock can function properly again.


Now, this might involve adjusting the door frame, reinforcing fixing points, or replacing damaged hardware. The goal is always the same. Restore a secure, properly closing door before leaving, and as professional door locksmiths we’re insurance approved, of course.

UPVC Doors and Multipoint Lock Problems

In our experience, uPVC doors are a frequent source of lock issues (trust us, we deal with enough of them). Now, we’re not saying that they aren’t a good door type, just that they are prone to certain issues not shared with other door types.

The handle lifts, but the locking points do not engage. The key turns but the door will not lock. In many cases, the gearbox inside the multipoint lock has failed.

We diagnose UPVC door faults by checking the rollers, hooks, gearbox, and door alignment. Sometimes a repair is possible. Other times, the safest option is to replace the multipoint lock strip.

Because we regularly carry compatible parts, most UPVC door issues are resolved during the first visit.

Smart Locks, Access Control, and Modern Lock Types

“Smart locks and modern locking systems are becoming more common in Richmond homes. When they work, they are convenient. When they fail, access can be completely blocked.”

We work on smart locks, access control systems, and electronic locking mechanisms alongside traditional locks. If a system fails, we regain entry using specialised tools and non destructive entry techniques wherever possible.

We also advise on whether smart locks are appropriate for the door and usage. Not every door benefits from them.

Lock Outs, Lost Keys, and Gaining Entry Safely

Lock outs happen quickly. A door closes behind you. Keys are lost. A broken key snaps in the cylinder.

Our emergency locksmith services cover lock outs and emergency lockouts 24 hours a day, days a week. We focus on gaining entry safely without damaging the door or frame.

Once inside, we assess whether the lock can be reused or needs replacing to restore security. You are never left with an insecure door.

Door Lock Problems Caused by Weather and Movement

Hot weather affects doors more than people realise. Timber expands. Frames shift slightly. Locks that were just about coping suddenly bind.

We see this every summer in Richmond homes. Doors become difficult to close. Locks feel stiff. Eventually, something gives.

Early adjustment prevents bigger failures. If the door no longer closes properly or the lock feels tight, it is worth addressing before it turns into a full breakdown.

Locksmith Services in Richmond That Go Beyond the Immediate Fix

When a lock fails, most people just want the door working again; it’s a given… That makes sense in the moment, but a good locksmith in Richmond looks beyond the immediate fault (like we do).

As part of our locksmith services, we check whether the issue is isolated or part of a wider pattern. And often, the faulty lock is the result of door movement, poor previous installation, or worn components that have been compensating for each other; only fixing the obvious fault rather than the root cause can leave the door vulnerable to repeat failure.

Home Security And Commercial Premises

As a local Richmond locksmith, we take time to assess the wider setup, which includes the door frame, locking mechanism, strike plate alignment, and how the door closes under pressure. If we see weaknesses that affect property security, we point them out clearly and explain the options.

This is especially important for home security and commercial premises where repeated failures become costly. Sometimes the solution is as simple as adjusting the door or upgrading to British Standard locks. Other times, it means planning lock changes that prevent future lock outs and emergency situations.

We provide honest security advice based on the property, not generic recommendations. That approach is what reliable locksmith services look like in practice.

How Our Emergency Locksmith Services Work

When we arrive on site, a professional locksmith assesses the situation properly, we explain what has failed, why it has failed, and what needs doing to restore security, then if repair is possible, we repair. But if replacement is the safer option, we explain why and carry it out properly.

For commercial customers, reliability matters even more. We work with commercial premises on access control, lock changes, and securing doors after hours so businesses can reopen safely.

And, because we are a local business, our reputation depends on doing the job properly. But what does that mean for you…?

No rushed fixes. No unnecessary work. Just qualified locksmiths delivering dependable locksmith services across Richmond (that’s our guarantee to you).
