Hello, it’s Sean Taylor from Lockforce. In this short video, I talk about thumb turn locks — what they are, how they work, and why they’re such a practical and important option for many homes and properties.
🧭 What Is a Thumb Turn Lock?
A thumb turn lock allows you to lock and unlock your door from the inside without using a key. On the outside, it works just like a standard cylinder — you still use your key to gain entry. But on the inside, there’s a small thumb turn mechanism that makes locking and unlocking quick and easy.
These locks are becoming increasingly popular, particularly in properties such as houses of multiple occupancy (HMOs), holiday lets, and family homes where quick and safe exit is essential in an emergency situation, like a fire.
🔥 Designed for Safety and Convenience
Thumb turn locks are primarily installed for safety reasons. In the event of a fire or other emergency, you don’t need to search for a key — you can simply turn the thumb mechanism and get out quickly.
This makes them ideal for any household where safety, speed, and accessibility are priorities.
🚪 The Problem with Traditional Cylinder Locks
In many homes, we still come across traditional locks where the key must be used on both sides. This can cause problems — especially in situations where someone leaves their key on the inside of the door.
For example, if an elderly homeowner or someone who needs support leaves their key in the internal side of the lock, it becomes impossible to unlock the door from the outside. This is something we’ve seen quite a few times when families or carers try to gain access and can’t, even with a key.
💡 Why Thumb Turns Solve the Problem
Thumb turn locks eliminate this issue completely. Because the inside mechanism doesn’t require a key, there’s no chance of the key being left in the lock. That means if a carer or family member needs to enter using an external key, they can — without being blocked by a key left on the inside.
This also prevents those moments where someone locks the door, closes it behind them, and accidentally leaves the key inside. It’s a small change that can make a big difference for security, accessibility, and peace of mind.
👩⚕️ Perfect for Carers, Key Safes, and Family Homes
If you’re responsible for checking in on someone — whether that’s an elderly parent or someone who needs assistance — thumb turn locks are a simple and effective solution. Even if you have a key safe outside, a standard cylinder lock with a key left inside will stop you from getting in. With a thumb turn fitted, access is always possible and secure.
✅ Final Thoughts
Thumb turn locks are a small but smart upgrade that improve both safety and accessibility. They’re especially beneficial for:
- HMOs and holiday lets
- Homes with elderly or vulnerable residents
- Properties with key safes used by carers or family
