Not sure which size cylinder you need?
Euro cylinders are measured in two halves, separated by the central fixing screw. Take both measurements from your existing cylinder before ordering, and match them to the size listed above.
A — Internal side
Measure from the centre of the fixing screw to the outer edge of the cylinder on the side that faces inside your home. Common sizes are 30mm, 35mm, 40mm, 45mm, or 50mm.
B — External side
Measure from the centre of the fixing screw to the outer edge of the cylinder on the side that faces outside your home. Common sizes are 30mm, 35mm, 40mm, or 45mm.
Cylinders are typically described as A/B — for example, a 35/45 cylinder has 35mm on the internal side and 45mm on the external side. Get both measurements right and the cylinder will fit your door perfectly.
Still unsure? Send a photo of your existing cylinder to info@homesecureshop.co.uk and we'll match it for you — or call 0151 521 8089 to speak to our team.
Product overview
Never carry a door key again. The BLACK X Smart Lock by Avocet ABS turns your existing door into a keyless smart entry system in minutes — unlock with your phone, a PIN, a fob, or a card, with a mechanical key backup so you're never locked out. And unlike most smart locks, it doesn't trade security for convenience: it's built to the TS007 3-Star Kitemark, the highest anti-snap standard for euro cylinders in the UK.
Why homeowners choose the BLACK X
- Highest-rated security, out of the box. TS007 3-Star anti-snap protection with ABS Snap Secure technology — if attacked, the cam locks and the door stays secure. No add-on cylinder guards or security handles needed.
- Certified cyber secure. Independently certified to IASME IoT Cyber Assurance Level Two — protected against digital attack as well as physical.
- Fit it yourself in minutes. A straight swap for your existing euro cylinder — no drilling, no wiring, no door modifications. Fits most uPVC, composite, timber, aluminium and steel doors, including patio and sliding doors. (Watch our install video below.)
- Share access instantly. Send guests, family, cleaners or Airbnb visitors temporary or permanent access from the free BLACK X app — and revoke it just as fast. No more spare keys under the mat.
- Up to 3 years on one battery. Runs on a single CR2 battery (included) with low-battery alerts in the app — no charging, no wiring, and a key override if it ever runs flat.
- Five finishes to match your door. Matte Black, Matte White, Polished Brass, Satin Nickel and Chrome, in 35mm–35mm and 40mm–40mm sizes.
- Grows with you. Add the xPad keypad for PIN entry, xKey fobs for kids or workers, or the Wi-Fi Bridge for remote control, real-time entry notifications and Alexa/Google voice control.
In the box: BLACK X Smart Lock cylinder · CR2 battery · 2 mechanical override keys · fixing screw · fitting instructions
