Straight answers
How much does a locksmith cost in Colchester?
With Replace Your Lock the part and the fitting are priced separately and shown before you book. Typical Colchester prices: lockout entry from £69, a standard euro cylinder replaced from £79 including the cylinder, an anti-snap 3-star upgrade from £110, a uPVC door gearbox from £160. No call-out fee, and the price is confirmed before any work starts.
I'm locked out in Colchester – how quickly can Chris get to me?
Chris covers Colchester and the surrounding towns and aims to be with you within 30 to 60 minutes when he's available; you'll get an honest ETA when you call. Entry is non-destructive wherever possible, so you usually keep your existing lock.
Can I change the lock myself instead?
Often, yes. A euro cylinder is held in by one screw and takes about ten minutes. Photograph your cylinder, we measure it and deliver the right one next day, and our guides walk you through it. If you'd rather not, Chris fits it.
What lock should I have on a uPVC door?
A TS007 3-star anti-snap euro cylinder. Lock snapping is the most common way uPVC and composite doors are broken into, and a 3-star cylinder is what most insurers and Secured by Design guidance expect.
My uPVC door won't lift and lock – is it the lock?
Usually the multipoint gearbox inside the door rather than the cylinder, sometimes just the hinges needing adjustment. Chris checks which before replacing anything; a gearbox is from £160 fitted, an adjustment is far less.
Do you cover Highwoods, Lexden, Stanway, Wivenhoe, Tiptree?
Yes: postcodes CO1 – CO7 and the villages between. Locks are delivered UK-wide if you want to fit them yourself.
Are you a real local locksmith or a national call centre?
A real local locksmith. You deal with Chris directly, he sets the fitting price, and it's agreed with you before he starts. Replace Your Lock supplies the locks and the booking; nothing is subcontracted through a call centre.
Do you do key cutting or safes?
Keys for locks Chris fits are supplied with the lock and extra keys can be ordered. For safes, vehicle keys or specialist work he'll tell you straight if it's not something he does and point you to someone local who does.
