Simple Process
How Lock Installation Works
From initial assessment to the finished installation - clear, professional, guaranteed.
Get in touch
Call us or fill in our contact form. Tell us what you need - a new lock fitted, an existing lock repaired, or advice on your options - and we will arrange a visit.
On-site assessment
Our locksmith examines the door and lock, identifies the best solution (repair or new installation), and provides a clear, no-obligation quote.
Professional installation or repair
Work is carried out to the highest standard using professional tools and quality hardware. We take care to protect your door and frame throughout the process.
Testing and handover
The lock is thoroughly tested to ensure smooth operation. You receive your keys, a demonstration of the lock, and a written guarantee for the work.
Repair or Replace? We Will Advise Honestly
Not every lock problem requires a full replacement. Locks can become stiff, misaligned or difficult to turn due to wear, weather damage, or failed components. Our repair service diagnoses the issue and fixes it at a fraction of the cost of a new lock. If a repair is not possible, we will explain why and offer a competitive quote for a lock change.
We fit locks from all leading manufacturers and can match existing lock brands if you need consistency across your property. Every new installation includes 3 keys, and we can supply additional copies or restricted-key profiles for enhanced security. If you have been locked out due to a faulty lock, we can gain entry and install a replacement in the same visit. Check our price list for installation costs.

Got Questions?
Lock Installation & Repair FAQ
Common questions about lock installations and repairs in London.
How much does a lock installation cost in London?
Lock installations start from £95 including the lock and 3 keys. The price varies depending on the lock type and door, but we always provide a quote before starting work. There is no call-out fee.
Can you add a lock to a door that does not have one?
Yes. We regularly fit locks on internal and external doors that do not currently have one. This includes fitting new mortice locks, rim locks, and deadbolts. Our locksmith will assess the door and recommend the best option.
Can you repair a lock instead of replacing it?
Often, yes. Many lock problems - stiffness, misalignment, a sticking mechanism - can be repaired without replacing the entire lock. We always try the most cost-effective solution first and will recommend replacement only when repair is not viable.
Do you install locks on fire doors?
Yes. We are experienced with fire door requirements and can fit compliant locks that do not compromise the door's fire rating. This is essential for landlords, businesses and HMOs.
What is an anti-snap lock and do I need one?
Anti-snap locks are designed to resist a common burglary technique where the cylinder is snapped to gain entry. If you have a uPVC or composite door with a euro cylinder, we strongly recommend upgrading to an anti-snap model - it is one of the most effective security improvements you can make.
How long does a lock installation take?
A straightforward lock installation typically takes 20 to 45 minutes depending on the lock type and whether any modifications to the door are needed. Your locksmith will give you a time estimate before starting.
