Why replace a euro cylinder
- Keys lost, or you've moved home
- The key is stiff, sticks or won't turn
- The cylinder is a basic, non anti-snap type
- The cylinder sticks out more than a few millimetres from the handle
How we solve it
Your locksmith will measure the cylinder exactly and fit a correctly sized replacement, ideally a TS007 3-star or SS312 Diamond anti-snap cylinder, so it sits flush with the handle.
How your locksmith helps
- Step 1
Measure
Both sides are measured from the fixing screw.
- Step 2
Swap
The new cylinder is fitted, usually in minutes.
- Step 3
Test
The key is tested with the door locked from both sides.
