Good afternoon,

Fitted a new euro lock today and the inside sits in around 2/3mm and is not flush. is this an issue or should I send it back to exchange it?

Thanks

You need to order the correct one and replace it, there are a variety of dimensions available +-5mm generally on either side so you can buy the perfect match for the old one. No "one size fits all" so to speak

Measured it before I purchased it with one of those plastic measuring euro lock tools and 40mm was protruding, so went for 34, fitted it it and it’s now in to far. It’s in the inside of the door just unsure if it will cause an issue.

Remove the new one and measure it, get a new new one in the correct size

It’s only likely to cause an issue if it causes the key to foul when turning.

A couple of mm protrusion is ok on the outside (the reason you aim for flush is to stop someone getting a pair of mole grips on and snapping the lock), but on the inside you can pretty much go as long as you want.

The outside is flush as it was 5mm too big.

The inside sits in as I went 5mm shorter as it stuck out. The key turns fine and doesn’t foul the inside of the door.

Will it allow moisture dirt in being like this and cause an issue?

What does it look like if you take it out, turn it around, and refit?

The ext is perfect and sits flush.

The inside sits in, as per picture I attached a couple comments up.

Wouldn’t be any harm swapping it for a slightly longer one, and it might look a bit better, but don’t think there’s any particular need to.

Ah, so both halves of the cylinder are the same length. Thought maybe you had an offset as putting them in the wrong way around makes a difference.

If the key doesn’t catch I wouldn’t bother swapping for a 5mm bigger lock unless it really annoys you.
If the outside is more or less flush that’s the main thing.

Sounds like you've got an offset application, but bought an equal length barrel insert. Length combos are

On a related note, burglary methods have evolved, and many anti-snap cylinders are no longer up to scratch. TLDR: Here’s a list of euro cylinders that pass the updated 'Diamond 2024' test:

The Sold Secure Diamond test has been updated to the Diamond 2024 test. The newer test includes attacks by four new burglary tools.

The 3-star tests are being updated, too. However, manufacturers have until 2027 to pass the tougher new tests, so until then, euro cylinders can continue to be sold with a 3-star kitemark despite being out of date.

Thanks for everyone’s advice and input, I decided to return and get a 5mm longer lock just so it isn’t sitting in like it was.
