Dorset's Lock Replacement Experts

If your keys have been lost or stolen, or if you've just moved into a new property, you have a critical security vulnerability: you simply don't know who has a copy of your keys. In these situations, changing your locks isn't something that can wait until next week. It needs to be resolved immediately to protect your home and your family.

Our local Dorset emergency engineers carry a comprehensive stock of cylinders, mortice locks, and uPVC mechanisms directly on their vans. This means we can replace almost any lock on the very first visit without needing to go back and forth to suppliers. We provide brand new sets of keys instantly and can even upgrade your property to Insurance-Approved British Standard (BS3621) or Anti-Snap (TS007) locks for total peace of mind.

Replacement Scenarios

Why Do You Need New Locks?

We carry hundreds of replacement cylinders, mortice locks, and nightlatches on our vans to resolve any security vulnerability in a single visit. Here are the most common situations we handle daily.

Lost or Stolen Keys

If your keys are missing, especially if they were lost with ID or stolen from your car/bag, your property is highly vulnerable. We arrive fast to swap out the cylinders and hand you a fresh set of keys immediately.

Moving into a New Home

Previous owners, tradesmen, dog walkers, and neighbours could all hold spare keys to your new property. Changing the locks on moving day is the only way to guarantee you are in complete control of your home's security.

Faulty or Insurance Upgrades

Is your key stiff and difficult to turn? A failing lock will eventually lock you out. We can replace faulty cylinders before they break, or upgrade your existing hardware to BS3621 and TS007 standards to satisfy home insurance policies.

How Our Lock Change Works.

Changing your locks shouldn't be a drawn-out process. Our dispatch model is designed to get your property secured with brand new hardware and keys in a single, efficient visit. Here is what to expect.

1
Quick Door Assessment When you call, our Dorset hub will ask whether your door is uPVC, composite, or wood. This helps us confirm the exact type of cylinder or mortice lock needed before we even leave.
2
Fully Stocked Arrival We dispatch the nearest engineer to your specific BH district. Because our vans carry hundreds of high-security locks, we almost never have to order parts or make a second trip.
3
Installation & New Keys The old hardware is removed and the new, British Standard or TS007 rated lock is installed. We test the mechanism and immediately hand over your fresh set of manufacturer keys.

Lock Replacement Facts

Lock Change FAQS.

We change hundreds of locks across Dorset every month. Here are the clear, honest answers to the most common questions our customers ask before we arrive.

Can you change the locks on a uPVC or composite door?
Yes, absolutely. Many homeowners worry that changing a lock on a multi-point uPVC door requires replacing the entire complicated strip mechanism. In reality, unless the mechanism is broken, we only need to swap out the central "Euro Cylinder" where the key goes in. This is a fast process and significantly less invasive than replacing the whole locking system.
How many keys will I get with my new lock?
Usually between 2 and 3 keys. The exact number depends on the brand and model of the lock we install. Standard euro cylinders typically come with 3 sealed manufacturer keys. If you require more copies for family members or tenants, let us know and we can advise on the best solution.
Do I really need to change my locks when moving into a new house?
We strongly recommend it. Even if the previous owners handed over a set of keys, you have no way of knowing how many duplicate keys were cut and given to cleaners, builders, dog walkers, ex-partners, or neighbors over the years. Changing your external door locks on moving day ensures you are the only person who can access your new home, and it also validates your home insurance policy.
