We’ve all been there — a bunch of keys, and you’re trying to find the right one. In this situation, we might think, “What if I could open multiple locks with the same key?”. Fortunately, it’s a real thing that can simplify daily life. Still, some homeowners find this system questionable when it comes to security.
Let’s discuss the benefits and potential risks of a one-key house system. Maybe it’s the security decision you are looking for.
A one-key house system does exactly what it sounds like — allows you to open multiple door locks with the same key. It means you can unlock your front door, back door, and any other entry point with just one key. You can typically get this set up by either hiring a locksmith to ‘rekey’ your existing locks so they all match a single key or by buying a new set of locks that are manufactured to work with the same key.
Switching to a one-key system is a big decision that can make your daily life easier.
The biggest benefits are convenience and simplicity. There’ll be no more situations when you try to figure out which key fits which lock. A quick call to a residential locksmith can set up this system for you, making those daily comings and goings much easier.
It sounds nice to have an opportunity to open two locks with one key, but it raises security concerns. If that one key gets lost or stolen, it’s like giving someone the master key to the entire home. The good news is that experienced locksmiths have options to make your one-key system more secure — special keys that are much harder for unauthorized individuals to duplicate. You might also find it worthwhile to explore modern alternatives, for example, wireless access control systems.
Typically, you can achieve multiple door locks that open with the same key in one of two ways. You can purchase a keyed-alike lock set. These sets are specifically designed so that every lock in the package will open with the same key right out of the box.
On the other hand, if you’re fine with your current locks but want the simplicity of a single key, you can hire a local residential locksmith to rekey your existing locks. They change the internal parts of your existing locks so that they all function with a new, matching key.
While this system makes getting in and out of your home much more convenient and can free up space on your keyring, it’s always a good idea to think about whether it’s the right choice for your specific security needs before making the switch.
Both rekeying and installing new locks have their benefits making it challenging to decide between them. Rekeying is a cost-friendly tune-up for your existing locks if they’re in good shape.
Although, you can buy a new set of locks that are already set up to work with a single key. This might be the better route if your current locks are older, you’re worried about their security, or you want to update your home’s appearance.
We all love the idea of simplifying our lives, and having multiple locks with the same key can certainly do that. However, when it comes to your home, you want to feel safe and secure above all else. If you are thinking about making the switch, consulting an expert is the best way to make sure your home stays both convenient and protected.
