Lock bumping / snapping

Your link doesnt work.

I have never come across a bumped lock, however snapping the barrel is very common around here.

Firstly get another handle - you can get solid ones that are much harder to remove, unless the cylinder protrudes from the handle it must be removed before they can even start to have a go at the lock with the usual tool. There are methods that dont require the handle removing but they are nowhere near as common

Some locks are designed to snap before the critical point to prevent entry, however this can still be overcome if you have a simple PVC door.

I beleive the Avocet ABS locks are rated quite highly, I know they are bump proof due to magnetic pins, and have quite a high resistance to snapping.

Give me a PM if you want more specific details, dont particulary want to post up how to burgle a house!

Swapped mine to Cisa Astral S's a few months ago, very happy with them.

I changed all my Euro cylinder locks after finding out how easily and quickly they are to get through. Apparently while I was away my GF locked herself out and a lock smith was able to get her back in the house in less than 2 minutes !

I changed mine to what looks like the ABS system which is a flat key with dips in it.

I read quite a lot before swapping my locks, I can't remember the details but I seem to remember reading a few unsavoury reviews about the durability of the Avocet range on locksmith and lock picking forums.

Yup had new DG installed just before Xmas. End of Jan the SiL gets done by lock snapping. Asked the guys who installed our DG whether thelocks on ours were anti bump & snap turns out they weren't! So had them changed for the flat key type look like an old time Vaux Cavalier key.

sounds like it. The only problem is that I can't get the keys cut anywhere apart from the locksmith that I bought it from. He's made replacements for all my Euro cylinder and I can used the same key for all of my doors and padlocks.

There's a new alternative to the ABS Avocet cylinder. Kaba has just launched its pExtra Guard lock cylinder, which meets the latest BS:2012:TS007 3 star rating vs. lock snapping.

a lock only keeps an honest man out

if they want in they'll get in

That's not good! Any particular brand that you'd recommend?

Unfortunately it does yes!

I don't know the ins and outs of the certification, but it looks like its main strength is that the sacrificial bit snaps very close to the cam, making it so you can't physically get your chosen tool in to snap it again. Unfortunately the simple way round this is to melt the plastic around the lock to create the room required to get purchase on the barrel.

The ABS cylinders lock the cam so you can't turn it even if its all snapped away. The Kaba ones may have something similar but non of their literature suggests this. Maybe it has very good bumping/picking protection that increases its rating at the expense of the snap protection, I don't know.
