Banham locks are one of the most trusted high-security locking systems in the UK, defending homes and businesses throughout London and beyond. They are generally known for their quality and reliability, which makes them one of the most utilised solutions in terms of property security enhancement.
One question a lot of homeowners ask is, should I fit my Banham lock myself or get a professional to do it for me? Nothing too complicated about DIY, in theory, but because they’re purposely designed to fit closely and be fitted tightly, Banham locks need to be properly installed for it to do its job.
You should now be able to make an informed choice between whether to follow a DIY installation of your Banham lock-or take advantage of professional help and installation as outlined in this guide that directly compares the two approaches head-to-head against each other for security, cost effectiveness and long-term reliability.
What Makes Banham Locks Different from Standard Door Locks?
Banham is an established British brand well known for producing high-end security locks designed to offer greater protection than traditional locking mechanisms. They are also a common choice for many London properties because of the intricate design and limited key space.
Key features include:
- High-security locking mechanisms.
- Patented anti-tamper technology.
- Restricted key systems.
- Durable construction.
- Insurance-recognised security options.
Precision fitting is essential. A slight misalignment can also affect the lock’s operation and hinder its efficiency.
- Hard time locking or unlocking the door.
- Faster wear on internal components.
- Reduced protection against forced entry.
- Increased repair costs.
A good lock offers maximum protection only when fitted properly.
What Does DIY Banham Lock Installation Involve?
Installing a Banham lock is more complex than replacing a standard lock and requires careful planning and accuracy.
Removing the Existing Lock
The old lock must be removed carefully without damaging the door or frame.
Measuring the Door
Accurate measurements are vital, including:
- Door thickness.
- Backset.
- Lock dimensions.
- Cylinder position.
- Fixing points.
Even minor measurement errors can affect the fit.
Aligning the Lock Body
The lock must be positioned correctly so the bolt aligns smoothly with the strike plate.
Installing Cylinders, Handles and Strike Plates
Each component must be fitted securely and accurately to ensure smooth operation.
Testing the Lock
After installation, check:
- Smooth key movement.
- Locking and unlocking.
- Bolt engagement.
- Handle operation.
- Door alignment.
If the lock feels stiff or difficult to use, adjustments may be needed.
Common DIY Challenges
Homeowners often encounter problems such as:
- Incorrect measurements.
- Poor lock alignment.
- Strike plate positioning issues.
- Door frame adjustments.
- Damage to lock components.
- Difficulty meeting manufacturer tolerances.
Unlike standard DIY locks, Banham locks are precision security products. Incorrect installation can affect both security and long-term performance, often resulting in costly repairs.
