I've had a break-in so looking to improve my security. I have what I believe is called a multi point lock - see pic. Basically when you lock the door there are pins at the top and bottom of the door that go into the frame, in addition to the dead bolt.
I have ordered a replacement Euro cylinder (this is in Ireland) that resists "bump" and "snap" (Avocet ABS MK3 Euro Cylinder) but was wondering if brute force was applied to the handle (say using a pipe as lever), could the lock be forced open this way?
Also, I want to add some internal bolts to the door, top and bottom. Given that the multi lock runs the entire length of the door, how near to the edge could I put wood screws in without hitting the locking mechanism? I don't want to take it out to look just in case I have problems getting it back in!
