Changing your door locks is one of the most effective ways to improve home security. In this case study, we detail how Keys4U helped a family in North London upgrade their entire locking system following a concerning security incident.
The Situation
A family returned from holiday to discover that their front door lock appeared tampered with. Although no entry was gained, the lock mechanism was visibly damaged. They called Keys4U for an emergency assessment and complete lock replacement.
Our Assessment
Our technician arrived within 25 minutes and conducted a thorough security survey. The existing locks were identified as:
- A standard rim cylinder vulnerable to bumping and snapping
- No secondary deadlock for out-of-hours security
- Worn door hinges allowing the door to sag and misalign
- Door frame showing signs of previous attempted forced entry
Recommended Upgrades
We recommended and installed a comprehensive security upgrade:
- British Standard TS007 3-star anti-snap euro cylinder
- 5-lever mortice deadlock for insurance compliance
- Door reinforcer plate protecting the lock area
- Hinge adjustment and hinge bolts for frame reinforcement
- New door viewer for visitor identification
Results
The entire upgrade was completed in under two hours. The family's insurance company accepted the new locks without requiring additional premium charges. Most importantly, the family felt safe in their home again, knowing they had professional-grade security protecting their property.
When to Change Your Locks
Consider changing your locks when moving home, after losing keys, following a break-in attempt, or if your current locks are over 10 years old. Modern locks offer significantly better protection than older designs.
