Why this happens
Top causes we see in Colchester
The five reasons we get called for lock change & replacement more than any others.
- 1
Insurance compliance
Most home policies require BS3621 mortice locks on final exit doors. We confirm yours and upgrade if needed.
- 2
Just moved in
You don't know who else has keys. Standard practice is to change every external cylinder on day one.
- 3
Anti-snap upgrade
Old euro cylinders are vulnerable to lock snapping. TS007 3-star anti-snap defeats this entirely.
- 4
Lost set of keys
A full cylinder change is cheaper than the risk of a returning bad actor with your address.
- 5
End of tenancy
Landlords and letting agents standard-rotate cylinders between tenants. We do these in batches.

Lock Change & Replacement — Common Questions
Common questions about our locksmith services in Colchester
When should I replace my locks?
You should replace locks when moving into a new property, after losing keys, following a break-in, if locks are worn or damaged, or to upgrade security for insurance purposes. British Standard BS3621 locks are often required by insurers.
What are anti-snap locks?
Anti-snap locks are euro cylinders designed to break safely if someone tries to snap them during a break-in attempt. The outer section breaks away but the locking mechanism remains secure, preventing entry.
Do I need British Standard locks?
Many home insurance policies require British Standard BS3621 locks on final exit doors. These locks meet rigorous security standards and are tested against common attack methods.
Can you replace locks on the same day?
Yes, we carry a wide range of locks in our vans and can usually complete replacements on the same visit. For specialist or high-security locks, we may need to order parts.
How many keys come with a new cylinder?
Standard fittings include three keys per cylinder. We can cut additional copies on the spot from £5 each. For master-key systems we set up coded suites with as many keys as you need.
What is TS007 3-star and do I need it?
TS007 is the British Kitemark standard for euro cylinders, with 1, 2 or 3 stars. 3-star cylinders pass independent attack-testing for snapping, picking, drilling, and bumping. Most insurers now expect 3-star on UPVC and composite doors.
Will new locks affect my house insurance premium?
Often yes — many insurers offer a discount for documented BS3621 + TS007 3-star upgrades. We provide a written security upgrade certificate suitable for your insurer at no extra cost.
Can you keep all my doors on a single key?
Yes, we can supply 'keyed alike' cylinders so one key opens every external door. We can also set up master suites where the front door key opens everything but back-door keys are restricted. Both add minimal cost over standard cylinders.
Which areas of Colchester do you cover?
We cover all of Colchester and surrounding areas including Lexden, Stanway, Highwoods, Wivenhoe, West Bergholt, Tiptree, Marks Tey, Copford, Eight Ash Green, Dedham, Langham, and Boxted. If you're in or near Colchester, we can usually reach you within 30 minutes.
How much does a locksmith cost in Colchester?
Prices vary depending on the job, but we provide clear, upfront quotes before starting work. A typical lock repair starts from around £65-£85, while emergency lockouts typically cost £85-£120. There are no hidden fees or call-out charges.
