How to measure a Euro profile cylinder.

A Euro cylinder is measured from the centre of the fixing screw to both sides. It is not one single length. It has an outside length and an inside length.

What to expect

Clear emergency process, no mystery price game.

I ask what happened, where you are, whether the door is shut or locked, whether the key is inside or lost, and whether an invoice is needed. Then I give a realistic arrival and price range.

Simple shut door

Damage-minimising opening first if the latch can be reached.

Locked door / lost key

May require drilling, pulling or cylinder replacement after explanation.

Company invoice

Billing address, e-mail and service details can be recorded.

Maps & route

Google, Apple and Bing route/profile links are available.

Measure from the fixing screw

Open the door and find the long fixing screw on the door edge at cylinder height. Measure from the middle of that screw to the outside and inside edge of the cylinder or fitting.

Direct measurement is more precise

If the door is open, loosen the fixing screw, turn the key slightly so the cam aligns, and pull the cylinder out gently. Then measure from the centre of the screw hole to both ends.

Do not use this for special locks

Panic bars, multi-point locks, rim locks, bar locks, deadbolt crossbars and internally blocked mechanisms are not normal DIY cylinder cases.

FAQ

Questions about measure Euro cylinder lock

What does 30/30 mean?

30 mm from the fixing screw centre to one side and 30 mm to the other side.

What if the cylinder does not come out?

Do not force it. The cam, fitting or lock case may be blocking it.

Can you help if the door is already locked?

Yes, but that is no longer a DIY measuring job. It becomes an emergency opening case.
