It depends on the cylinder you choose and on your door, so we do not give a general figure: we give you a fixed quote before we start.
What matters most:
- The security level. A basic cylinder is not the same as an anti-bump, anti-snap or high security one with a key registration card.
- The size. The usual sizes are easy; unusual or very long ones change things.
- The door. Wood, security door, aluminium or uPVC.
- Whether it comes with an escutcheon or some adjustment to the lock.
Send us a photo of the cylinder from the outside and another of the edge of the door on WhatsApp and we will tell you the options and the quote. If anything changes when we arrive, we tell you before carrying on. Ask for it on quote.
