Your locks are your first line of defence against intruders. But many people only think about changing their locks after something has gone wrong. In this guide, we explain the key situations when you should proactively consider lock change services — and why acting early can save you from a much bigger problem.
1. Moving Into a New Property
This is the most important time to change your locks. You have no way of knowing how many copies of the keys exist or who has them. Previous owners, estate agents, contractors, and neighbours may all have copies. Changing the locks when you move in gives you complete control over who can access your new home.
2. After a Break-In or Attempted Break-In
If your property has been burgled or targeted by an attempted break-in, your existing locks may be damaged or compromised. Even if the locks appear undamaged, a professional locksmith should assess them and recommend replacements. This is also an opportunity to upgrade to higher-security locks.
3. Lost or Stolen Keys
If you have lost your keys or had them stolen, you should change your locks immediately. If your keys were stolen along with any identification showing your address, the risk is even greater. Do not wait to see if the keys turn up — act quickly.
4. After a Relationship Breakdown
If a partner, housemate, or family member moves out and the relationship has ended on difficult terms, changing your locks is a sensible precaution. This is particularly important if there has been any history of conflict or harassment.
5. Worn or Damaged Locks
Locks that are stiff, difficult to operate, or showing signs of wear should be replaced. A worn lock is easier to pick or force, and a lock that fails at the wrong moment can leave you locked out or unable to secure your property.
6. Upgrading Your Security
If your locks do not meet British Standard BS3621, they may not provide adequate protection — and your home insurance may not cover you in the event of a break-in. Upgrading to British Standard locks is a straightforward and cost-effective way to improve your security.
7. After a Tenancy Change
Landlords should change locks between tenancies as a matter of course. This protects new tenants and reduces the landlord's liability.
