The security of a front door should be thought of like a chain; it is only as good as its weakest link.
If you have a brand new, handmade, bespoke front door fitted with flimsy locks, then clearly it’s security is limited by its locks. One big kick, the lock’s fixing screws may give and in you go.
The same high quality front door, fitted with high quality locks but hung in an old, repaired Victorian front door frame, will fail because the lock keeps will break out of the frame when it is attacked.
A flimsy, cheap door in a new, hardwood door frame, fitted with great locks, may simply fall to pieces when a burglar puts his size 9s through it.
However, a new, strong door, with excellent locks, fitted to a new hardwood door frame is a very different matter, which may result in the burglar visiting A&E with a broken foot, rather than his pals in the pub with his stolen loot.
