This is the situation: You put the key in, it turns like normal… but the door just won’t open. No resistance. No click. Nothing. For sure, it’s one of those situations that catches people off guard.

You can get in touch with NW Locksmith whenever you need assistance with your lock. We will definitely be able to assist you with all these lock issues anytime!
What’s really happening inside the door
This is what actually happens: when you turn the key, you’re not directly opening the door.
You’re activating a mechanism inside. A gearbox, latch system, or internal linkage that pulls the latch back. If the key turns but nothing happens, it usually means:
- The internal mechanism has failed
- The connection between the cylinder and the lock body is broken
- or parts inside have worn out or snapped
This happens a lot with UPVC doors, especially the multipoint ones. They just wear out over time, nothing unusual. From the outside, everything feels normal. Inside, it’s not engaging at all.
The most common causes (from real jobs)
After dealing with this kind of issue all over North West London, these are usually the main scenarios our locksmith company is dealing with every day:
1. Failed gearbox (very common)
You know, the internal gearbox wears out over time. The key still turns, but it’s no longer connected to anything. This is a pretty common issue in NW London.
2. Broken spindle or linkage
This connects your handle and lock mechanism. When it goes, you lose control of the latch.
3. Worn multipoint lock system
With older doors, multiple locking points stop responding properly.
4. Misalignment (less common in this exact scenario)
If the door has dropped, the parts don’t line up. But usually, you’d feel resistance, not a free turn.
Sometimes it works one minute and then just doesn’t the next, no warning, which is what catches most people out.
Can you fix it yourself?
Many people are asking us when they call if they can fix it by themselves. Well, in short, we would not advise you to try, as you might break the internal parts. Sometimes people try:
- pulling the handle harder
- turning the key repeatedly
- forcing the door
This usually makes it worse.
If the internal mechanism has gone, no amount of turning will reconnect it, and forcing it can damage the door or frame.
When it turns into a lockout
Here’s where it gets frustrating.
You might still be able to lock the door… but not open it again. Or worse… you step outside, shut the door, and suddenly you’re locked out with a fully failed mechanism.
At that point, it becomes an emergency.
If that’s where you are now, this is exactly the kind of issue covered here:

Repair or full replacement?
In most cases, this isn’t about changing the key or cylinder.
It’s a mechanism problem, not a key problem.
That means:
- replacing the gearbox
- repairing or replacing the full lock mechanism
- sometimes adjusting alignment at the same time
You can see how that works here:
