Which lock do you need?
New owners in Witham, Billericay and Chelmsford can have the locks changed on moving day, and landlords in Harlow and Braintree can do the same between tenants.
uPVC and composite doors use a euro cylinder. We fit anti-snap cylinders, which resist the snapping attack burglars use on cheap cylinders. Timber front doors usually have a nightlatch and a mortice deadlock; for insurance that deadlock should be BS3621.
Most lock changes in Chelmsford take 30 to 45 minutes. Common reasons: moving into a new home, lost or stolen keys, a tenant moving out, or a lock that has become stiff and worn.

Lock change in Chelmsford: common questions
How much is a lock change in Chelmsford?
From £88 supplied and fitted for a standard euro cylinder. BS3621 mortice deadlocks start from £109. The price the engineer confirms includes the lock and the fitting.
Do I need anti-snap locks?
On a uPVC or composite door, we recommend them. Snapping is the most common way in through those doors, and anti-snap cylinders are built to resist it.
How quickly can someone get to me?
An engineer is typically with you in 15 to 20 minutes, and within 30 minutes at most. We give you a time on the phone based on where the nearest engineer is right now.
How do I pay?
When the job is finished. Card, cash or bank transfer, and you get a written receipt you can use for an insurance claim.
How does pricing work?
Tell us the door, the lock and what has happened, and we give you a free quote on the phone. When the engineer arrives, they check the lock and confirm the final price with you before starting any work. Nothing is done without your agreement. A £49 assessment fee applies only if you cancel after the engineer has arrived.
Can you change locks for a landlord or letting agent?
Yes. Between tenants is one of the most common jobs we do. We can fit cylinders keyed alike so one key opens the front and back doors.
Do you cover Brentwood, Harlow and Maldon as well as Chelmsford itself?
Yes. Our engineers work across the CM area, including Brentwood, Billericay, Harlow, Braintree, Witham, Maldon and the villages around them.
I get back from London late and have lost my keys. Can someone still come out to Chelmsford or Shenfield?
Yes. The line is answered 24 hours a day and there is no callout fee if you go ahead, so a late train home is no problem. Tell us the address and an engineer comes straight out, usually within 15 to 20 minutes, and confirms the price before starting.
