I was aware how fragile the Eurolock type cylinder on PVC doors (and timber ones ) was. Easy to break.
However last week I had a demo which was a bit more revealing.
First a device which snaps the lock. A screw is screwed into the key slot, and this is then pulled by tightening a bolt, which pulls it, and the barrel snaps. Then the lock can be opening by jigging a screwdriver in it. Lock opened in 20 seconds, but a bit of noise
Next, a "bump key". A special key is lightly tapped into the lock and twisted. Lock opens in seconds
Next an auto opener. Same principle as a bump key - a tough wire taps all the pins up while the barrel is turned. Opens with 10 seconds.
Next a standard pick. Lock opens in 10 - 30 seconds
So don't think your multi-point lock is good. Your barrel is likely to be insecure, and the weak point of the whole door
And check your insurance. Most specify a BS 5 lever lock to doors - not a Euro cylinder
