Signs there's been an attempt
- Scratches or metal marks around the cylinder that you don't remember being there before
- The cylinder turns more loosely or differently than usual, even if the door still closes properly
- Pry marks on the frame or the edge of the door
- Metal shavings on the floor, near the lock
- The door is harder (or easier) to close than normal
What to do first
If the door is still closing normally and no one has got in, there's no immediate emergency, but it's not something to ignore either: a lock that's been tampered with, even if it held this time, may have been weakened and give way next time. Take photos of the marks before touching anything, in case you need them later for a police report or for insurance.
When to call the police and when to call a locksmith
If you suspect there's been an attempted break-in, the first thing is to work out whether there was actually access to the property (even partial) — in that case, it's advisable to call the police before touching anything, the same as you would after a burglary. If the door was never actually opened and you just want to check the state of the lock and reinforce it, that's where a locksmith comes in: we assess whether the cylinder has been damaged, whether it's worth repairing or replacing it, and what improvements would make sense so it holds up better next time.
How to reinforce the door afterwards
- Replace the cylinder if it's been damaged or weakened, even if it still works
- Install a security shield if the cylinder is exposed
- Consider a high-security lock if the current system is old
- Ask for a security audit if you want a full review of the door, not just the lock
If you're not sure whether what you're seeing is a real attempt or just normal wear, send us photos over the phone or call us and we'll help you assess it, no obligation.
