I would refer you back to my original post. A single point of security will not withstand a brute force attack. The striker plate and rebate on your mortice lock are in the same piece of wood that failed on your night latch attack. The night latch didn’t break. The wood did. That wood will fail just the same when it’s wrapped around the mortice bolt as the bolt on the night latch. On your new front door you have 3 points of security and bolted hinges. That’s a more secure door. And if you noticed when it was installed, the bolts that slide across don’t go into wood, they go into a re-enforced rebate in the door frame, not the surround. So there is no wood to fail. As I said above, you won’t kick that in.
My mind isn’t skewed anywhere other than ‘how do I gain access?”
If my decision on “how do I gain access?” is a brute force attack then your mortice lock is no better than your night latch. Don’t fool yourself that a British Standard Kite Mark makes your wood tougher.
. I was actually thankful I was able to kick it in quite easily otherwise I would have had an awkward and embarrassing phone call with my boss explaining why I would be late.
