When Do You Need a Fresh Lock Installation?
There are many reasons to fit new locks — here are the most common situations our customers contact us for.
Moving Into a New Property
Never know who has a copy of the old keys? A fresh lock installation is the first thing you should do when moving.
Lost or Stolen Keys
If your keys have been lost or stolen, fitting new locks immediately is the most effective way to protect your home.
After a Break-In
Following a burglary, your existing locks are often damaged or compromised. Fresh locks restore your security.
Worn or Faulty Locks
Old locks can become stiff, difficult to operate or simply fail. Replacing them prevents inconvenient lockouts.
Change of Tenancy
Landlords and letting agents should always fit fresh locks between tenancies to protect new tenants.
Security Upgrade
Upgrade from old standard locks to high-security anti-snap, anti-pick, anti-drill cylinders — required by most insurers.
