The cylinder, or barrel, is the part of the lock your key goes into. Replacing it is the quickest way to change who has keys and to upgrade security, and on most doors it takes minutes.

We stock euro, oval, rim, screw-in and British Standard cylinders from ABS, Avocet, Union, ASEC, ERA, EVVA, Caveo and TSS, including TS007 3 star anti-snap cylinders. Measure from the centre fixing screw to each end of your current cylinder to get the right size.

Buy it, and we can fit it. We are not just an online shop: our own locksmith engineers can install what you order, so you get the right product and a proper installation from one company. Fitting is available across England from £70.80 per hour including VAT (£59 + VAT) on weekdays, and £82.80 including VAT (£69 + VAT) from 5pm, at weekends and on bank holidays. Just tick I require installation on the product page when you add it to your basket, or call 0333 305 2967.
