When you’ve just moved into a new house or flat, it’s impossible to know who still has a set of keys. Old owners, tenants, estate agents, builders – anyone could still have access.
One of your first tasks when you get the keys to your new home should be ensuring home security.
You might think the keys you got on completion day are all there is, but how can you be sure?
There are several reasons why our customers, and other people up and down the country, choose to install new locks on their new property. Here’s why new house homeowners and tenants call us to change the locks:
Previous owners may still have keys.
Ex-tenant family members may still have keys
How many copies were given to tradesmen or estate agents.
You don’t know how many keys are in circulation from the previous owner.
Old locks can be weak or worn.
Insurance policies often expect secure, updated locks.
A proper lock replacement or lock rekey gives you peace of mind and takes care of any security risks in your new house from the start.
The main reason people skip it is because it feels like another expense after a costly move — but it’s one of the cheapest and most important security measures you can take. Particularly on any exterior doors, getting new keys and new locks installed really is a good idea.
Plus, there is something a little bit satisfying about it, isn’t there? After all, do you really want the same key as the previous occupants?
It really is as simple as new locks on a new property of yours, (both residential and commercial properties), giving you an additional layer of safety and peace of mind.
Sometimes you don’t need to replace the whole lock. If the hardware’s sound, we can rekey it instead.
That means we change the inner mechanism so old keys won’t work, and you get a new set without having to replace the entire fitting.
It’s a solid option and simple fix if you want:
A fresh start after moving in
One single key for all the doors
To keep good-quality locks already in place
We can also set up a master key system if you want one key that works across your property – handy for front and back doors, garages, and side gates.
Moving day’s stressful enough. You don’t want to wait around worrying about who’s got your keys.
As professional locksmiths, we offer a same-day lock change service across London. Most of the time, we can be with you within hours.
