Reviews
What Carshalton customers say
“Snapped the key in the lock on a Sunday morning. Out within the hour, key extracted, new cylinder fitted, and the chap even oiled the hinges while he was at it.”
Eleanor W. · Carshalton · Snapped key · 5 days ago
“We'd just bought the house and wanted every lock changed. One visit, keyed alike, and a proper explanation of what BS3621 actually means for the insurance. Very reassuring.”
Graham T. · Carshalton · Moving house · 2 weeks ago
“Honest to a fault — told me the lock could be repaired rather than replaced and charged accordingly. Rare these days.”
Nadia K. · Carshalton · Lock repair · 3 weeks ago
We don't do car keys. Cosmo Locksmith is a home and business locksmith. For vehicle lockouts or key programming you'll want an auto locksmith.
FAQ
Questions people ask us
Are your locks insurance approved?+
Yes. We fit BS3621 mortice locks and TS007 anti-snap cylinders, which is what most home insurers ask for, and give you a dated receipt showing the grade.
Do you do car keys?+
No. We're a home and business locksmith and don't cut or programme vehicle keys. For a car lockout you'll want an auto locksmith.
Will you damage my door getting in?+
Almost never. Our engineers are trained in non-destructive entry and open the vast majority of locks with no damage. If a lock does have to be drilled, we tell you first and fit a new one on the spot.
I've been burgled in Carshalton — what do I do?+
Ring the police for a crime reference number, then ring us. We'll secure the property the same day, repair the door and frame, fit new locks and give you a written report for your claim.
