Is Master Key for Your Home Safe?

Posted on: 14 September 2020

One key to open all your locks—it sounds like a fantastic solution for someone who ordinarily might have to carry around a bulky key ring to open all the locks on their property. You might have heard of the idea of having all your locks configured to accept the same key, which is referred to as a master key. Sure, it can make life easier, but with all your locks accepting the same key, does this pose a security risk for your property?

The Cheapest Option

In its most basic and inexpensive implementation, a master key for all your locks can create a gap in your property's security. The cheapest way to set this up is to purchase and install identical locks at all applicable entry points (front door, side door, back door, etc.), all with an identical key. The trouble is that you're not going to be the only one with this key.

Identical Locks

Although mass-produced locks are generally sturdy enough, their identical nature can create a problem. Looking at the locks on offer at your local hardware shop, you will notice that many of the locks have identical serial numbers. Essentially, anyone else who purchases this lock will have a key that can grant them access to your property. Yes, the risk is low, but it exists, and it's best to avoid it altogether.

Re-Key Those Locks

You can have a mass-produced lock on your exterior doors, but you shouldn't have a mass-produced key. A mobile locksmith can visit your home and quickly re-key your locks. Basically, the pins inside the locking mechanism are reconfigured to only accept a new key with unique notches in its blade. This means that any other keys out there, regardless of who manufactured the lock, will not work with your newly re-keyed locks. All your locks can be re-keyed to the same configuration so that a single key can still unlock all the entry points to your home.

Smart and Biometric Locks

You could also upgrade all your conventional locks to smart locks, opened via a unique signal generated by your smartphone. You can either manually activate this on your phone to open the lock in question, or your smartphone can send a proximity notification to the lock via Bluetooth so that it unlocks as you approach. Another option is a biometric lock, activated via a scan of your fingerprint. 

A master key doesn't necessarily pose a safety risk for your home, but it can if you don't alter the locks for an additional level of security. Speak with a mobile locksmith to learn more.
