How to Diagnose a Door Alignment Issue | Lock Not Working in Hot Weather?

Is your uPVC or composite door suddenly hard to lock? It could be an alignment issue — often triggered by warm weather. In this video, Andy from Lockforce Locksmiths shares a quick and easy way to check if your door problems are caused by misalignment, rather than a faulty lock, handle or cylinder. 🔧 This issue is particularly common in warmer months, as doors expand slightly with heat, making it harder for locking points to line up properly. Fortunately, in many cases, a simple hinge adjustment can solve the problem. ✅ Perfect for: • Door won’t lock when hot • Handle won’t lift or lock properly • Stiff or grinding mechanism • Diagnosing multipoint lock issues • DIY door alignment tips 📹 What you’ll learn in this video: 00:00 – Common symptoms of misaligned doors 00:42 – Handle lift test with the door open 01:15 – How to confirm locking strip is fine 01:45 – When it might be something more serious 👉 If the locking mechanism works smoothly with the door open but not closed, chances are it’s just a door alignment problem — not a broken lock. 📞 Still unsure?
