A lock change is one of the most effective ways to improve your home security, but many people are unsure when it is actually necessary. This guide explains the key situations when you should consider a lock change — and why acting promptly can protect your home and family.
1. Moving Into a New Home
This is the single most important time to change your locks. When you move into a new property, you have no way of knowing how many copies of the keys exist or who has them. Previous owners, estate agents, builders, and neighbours may all have copies. A lock change gives you complete control from day one.
2. Lost or Stolen Keys
If your keys have been lost or stolen, change your locks immediately. If the keys were stolen along with any identification showing your address, treat this as an emergency and call a locksmith straight away.
3. After a Break-In
Following a burglary, your locks may be damaged or compromised. Even if they appear undamaged, a professional locksmith should assess them. This is also an opportunity to upgrade to higher-security locks to prevent a repeat.
4. End of a Tenancy
Landlords should change locks between tenancies as standard practice. This protects new tenants and reduces the landlord's liability. Tenants who have had a difficult relationship with a previous landlord may also want to change locks when they move in.
5. 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.
6. 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.
7. Upgrading Your Security
If your locks do not meet British Standard BS3621, upgrading is a straightforward way to significantly improve your security and ensure your home insurance is valid.
