Choosing The Right Replacement Cylinders & Latches

Cylinder type: Select double euro cylinders for doors requiring key operation from both sides, half cylinders for single-sided access, or thumbturn cylinders for interior convenience with key-operated external access.

Measurements: Accurately measure your existing cylinder from the centre screw hole to each end. Common sizes include 30/30mm, 35/35mm, and 40/40mm configurations, though custom lengths are available for specific applications.

Security rating: Consider the security level required for your application. Look for anti-snap, anti-drill, and anti-pick features, particularly for external doors and high-risk locations. Check insurance requirements which may specify minimum security standards.

Lock type: Mortice deadlocks provide robust security for external doors, while mortice sash locks combine deadlocking and latch functions. Choose between 2-lever, 3-lever, or 5-lever mechanisms depending on security needs and insurance specifications.

Finish and keying: Select finishes that match existing hardware. Consider whether you need keyed-alike cylinders for multiple doors or master key systems for commercial applications.

Frequently Asked Questions

How do I measure a euro cylinder correctly?

Measure from the centre of the fixing screw hole to each end of the cylinder. Record these as two measurements (e.g., 35/35mm). The cylinder should not protrude more than 3mm beyond the door handle to prevent snapping attacks.

What's the difference between a deadlock and a sash lock?

A mortice deadlock provides a single deadbolt operated by key only, ideal for doors without handles. A sash lock combines a deadbolt with a latch mechanism, allowing the door to be opened with a handle while still providing key-operated security.

Can I replace a euro cylinder myself?

Yes, replacing a euro cylinder is straightforward for competent DIYers. Simply remove the retaining screw, insert the key, turn slightly to align the cam, then withdraw the old cylinder. Reverse the process to install the new cylinder. However, MyToolShed.co.uk recommends professional installation if you're unsure or for high-security applications.
