Frequently asked questions

I've been burgled. What do I do?

Being burgled is horrible. The best thing you can do is call us and we'll make sure your property is safe and secure. We can replace locks and give you new keys or we can rekey the original lock. We can also fit new locks to vulnerable doors and windows.


What if something goes wrong with my lock?

It's rare that a new lock we provide will prove to be faulty, but in the event that it does, you're covered. All of our work comes with a full guarantee so if you're not satisfied, we'll make the necessary changes without charging extra. You can't say fairer than that.


Can you replace locks on the weekend?

Yes. Lock replacement is one of the measures included in our 24-hour locksmith service. We realise that you never know when you'll need a locked replaced or repaired, so we're here to help when you need us. All you need to do is get in touch.
