When a door is forced open — whether in a burglary or an attempted break-in — the damage is rarely limited to the lock itself. The frame, the keep, the door leaf, and the hinges can all be affected. Understanding what's been damaged and what the priorities are helps you make sensible decisions quickly in a stressful situation.
How Doors Are Usually Forced
The most common method of forced entry on a residential door is kicking or shouldering — applying sharp force to the door at the point of the lock, which causes the frame to split at the keep (the metal plate the bolt or latch sits in). This is effective because in many properties the keep is only held by short woodscrews into the door frame lining, which has little resistance to sudden force.
The second most common method on uPVC and composite doors is lock snapping — where the cylinder is attacked — followed by mechanism manipulation. In these cases, the frame damage is minimal but the lock hardware needs replacing.
What Gets Damaged
The Door Frame
On a kicked door, the frame typically splits at the keep area. The timber splits along the grain under the force, and the keep is torn partially or fully out of the frame. The extent of the damage depends on the quality of the original installation — doors with deep, long-screwed keeps into solid timber or steel reinforcement are much more resistant.
Frame damage ranges from a clean split that can be repaired and reinforced, to complete destruction of the frame section that requires replacement of that part of the frame. A locksmith can carry out emergency boarding and basic repairs immediately, but significant frame damage may require a joiner or window and door specialist for a permanent fix.
The Keep
The keep (also called a strike plate) is the metal plate in the frame that the lock bolt or latch engages with. On a forced door, this is almost always damaged or torn out. Even if it looks intact, the woodscrews or fixings behind it will have been stressed and the keep should be replaced and refitted properly — ideally with longer screws into solid timber behind the frame lining.
The Lock
The lock mechanism itself may or may not be damaged depending on how entry was achieved. On a kicked door, the lock mechanism is often undamaged — the frame gave way before the lock did. The cylinder, mortice lock, or nightlatch may only need the keeps replacing and the door realigned rather than replacing the lock itself.
If entry was through cylinder snapping, the cylinder needs replacing. If the door handle or mechanism was forced, those components need assessing and likely replacing.
The Door Leaf
The door itself sometimes cracks or splinters at the lock area on a heavily forced entry. This is more common with lightweight hollow-core doors than solid or composite doors. If the door leaf is structurally damaged, it needs replacing — a damaged door can't be adequately secured regardless of the quality of the lock fitted to it.
The Hinges
On a severely forced door, hinge fixings can be pulled or the door can be knocked partially off its hinges. Check that the door hangs correctly and opens and closes squarely — a door that's off its hinges will be immediately obvious.
Emergency Securing After a Break-In
The immediate priority after a break-in is securing the property before you sleep there again. A locksmith can:
- Board a door that can't be closed or locked securely — temporary boarding while permanent repairs are arranged
- Replace a damaged or snapped cylinder
- Refit or replace a damaged keep with long-throw screws into solid timber for improved resistance
- Fit additional security — a door bar or security chain — as a temporary measure if the frame needs more significant repair
- Assess the overall security of the door and advise on permanent repairs
On insurance: Photograph all damage thoroughly before anything is repaired or replaced. Your insurer will need evidence of the damage for the claim, and a locksmith's invoice for emergency securing may be claimable as part of the repair costs. Check your policy for emergency assistance cover — many policies include 24-hour helplines for exactly this situation.
Making the Door More Resistant When You Repair It
A forced entry is an opportunity to address the vulnerabilities that made it possible. When the frame is being repaired, consider:
- A heavy-duty, deep keep with 100mm+ screws into the solid timber stud behind the frame — this alone makes the most significant difference to kick resistance
- A door security bar or multi-point lock if only a single-point lock was fitted before
- Hinge bolts on the hinge side of the door, to prevent it being forced from that side
- An anti-snap cylinder if the existing cylinder was basic
