Does My Door Type Affect The Type Of Door Lock I Need?

Does My Door Type Affect The Type Of Door Lock I Need?

Many things affect the type of door lock you need including its location (internal or external), your preferences and the level of safety required. 

But the main factor is the type of door. 

Overall the type of door lock you choose must comply with BS3621 (British standards), which all of our door locks here at LockShop Direct do. 

Today we’ll be talking you through the recommended type of door locks for your door type. 

Wooden Doors


An exterior wooden door is most suited to a mortice lock or rim cylinder lock with a deadlatch. 

If you’re opting for a mortice lock, we advise a minimum of a five-lever mortice to meet both insurance requirements and British standards. 


Whether it’s a bathroom, bedroom or office, the best lock for an internal wooden door is a mortice sash lock. 

As internal door locks aren’t a requirement, a three-lever mortice lock will suffice. 

For rooms where you require privacy but not necessarily protection from burglars, we recommend a simple turn and release lock - they’re an affordable option and aren’t difficult to install. 

uPVC and Composite Doors 

Cylinder door locks are the most appropriate for uPVC and composite doors. 

They require a key and can be locked and unlocked from both inside and out. 

Many homeowners choose to install cylinder door locks in their external doors as they’re anti-pick and anti-drill, so you can relax knowing you, your family and your possessions are safe. 

Steel and Aluminium Doors 

Steel and aluminium doors are often installed for an extra level of security, which is further supported by cylinder locks and handles. 

Being a heavier-duty lock style, you can count on cylinder locks to maintain your levels of security. 

Other considerations when choosing a door lock 

While the material hugely impacts what type of door lock you should buy, there are a few other factors to consider. 

Each door has a security rating, which door locks must align with. Determine the rating of the door and use this to help you decide how heavy-duty your new door lock should be. 

While door locks add an extra level of security to your home, the overall quality of your door frame is important. If you have a high-quality door lock and a brittle door frame, you’ll be making yourself equally as vulnerable as if you had no lock at all due to how easy it would be to break in. 

Although the main priority of a door lock is security, it’s only natural to want it to look good and suit the aesthetic of your home. We have a wide range of colours and finishes to suit your style. Shop our range of door locks today.
