On this job we had a failed BKS euro cylinder lock. We were called out to a customers house as he couldn’t open the rear door to the property from the inside. When the handles were removed I could see that the euro cylinder had snapped in half. That would be great if it had stopped an attempted break in from outside, but this was a snapped euro cylinder from the inside of the property. Once I’d removed it from the door I could see that the sacrificial cuts for this brand of euro cylinder were on just one side of the cylinder and it had been fitted in to the door the wrong way round – ie no security from outside if you were trying to get in from out there, but if you try to defeat the lock from the inside you’ll find extra security stopping you in your tracks.

I replaced the euro cylinder with a good quality anti-snap euro cylinder to the door so that the customer can use that door again.

Makes me wonder how many other people have the euro cylinder fitted the wrong way round in their doors… The customer said he’d had someone come and look at the doors a while back and they did something to make it easier to open. It’s a shame they didn’t notice the euro was the wrong way round when they were here – unless they were responsible for turning it around…

Lesson learned. You need a competent professional working with your security, and not someone who says they have done it once before and they think they know how to do it. This could have been serious. This property could have been broken in to by snapping the euro cylinder as it was incorrectly fitted.

It was a British Standard 3* cylinder too, which is the highest grading of security we do in the UK for euro locks. Just shows that you can have the best level of security, but if it isn’t fitted correctly then it’s useless.

We always recommend snap safe euro locks. These have a sacrificial cut in them that runs around the cylinder body and the plug that turns in the cylinder. You can hold the cylinder up to the light and see right through the cut section. If and side torque is applied to the euro cylinder it will snap in two. Burglars want the lock to snap where the cylinder fixing screw goes through the lock to secure it in to the door, but the sacrificial cut break-off point is away from there so the would be theif is stopped in their tracks.
