You mean snapping with screw in it and pulling with hammer? If yes, i wonder how that latch which holds cylinder is pulled away...

the cylinder will snap where the screw goes through it that secures it to the door. you can buy other types which snap in a better manner to deter thieves.

So should i do like this?



Will i need to use screw that fits tightly?

P.S. I was offered Yale cylinder which was almost 2 times more expensive. I also say on YouTube Yale anti-lock cylinder. Did you mean this cylinder when told that i can buy other types which snap in a better manner to deter thieves?

Anti-lock and anti-bump are not related?

i would have thought so boris. otherwise the screw will come out. i will say ive never had to do this. but no doubt will do one day.

my dads done it before with a cold chisel and a mash hammer.

these are something like what i meant http://www.discountlocks.co.uk/Anti-Sna ... tAodgEC8Ag

I liked anti-snap and turn cylinder. Won't require finding keys to unlock my room's door and more convenient than this euro cylinder that i have bought recently:

In your 1st picture it shows the door unlocked, plus the screw which retains the lock has already been removed.
Why dont you just slide the lock out and fit the new one.
If its stiff give it a good belt with the hammer.

hasnt he lost the key though? as the keys normally needed to remove it hence the question about snapping the lock

I changed one last year, the key had snapped in the lock but was in the unlocked position, same as original photo, I just took the holding screw out and could remove the barrel.

The metal arm coming out the side of barrel will not be in line,so will not pull out,I did one at xmas and just drilled it out,used a pilot bit then larger,then you can line metal arm up and pull out,took about 10 mins,surprised how easy it was

Must i choose correct bit carefully? If yes, which drill bit must it be and what is pilot drill bit? Isn't lock snapping with screw easier and less hassle compared to drilling?
