Keyed Alike Locks Guide

Are you thinking of having your locks keyed alike? We will cover the benefits of keying alike and what door locks can and cannot be keyed alike.

What does Keyed Alike Mean?

Keyed alike means one key fits all locks, for example your front and back door locks can both use the same key or every lock in an office can use the same key.  Having your locks keyed alike is very beneficial if you want to open & close all your door locks with one key.

Want to know if keying alike is a good idea or not? Next up will cover the pros and cons.

Advantages: 

The main advantages for having multiple door locks with one key (keying alike) are:

  • 1. Time Saver – Saves time without having to carry a set of keys around for every lock in the house or building.
  • 2. Save Money – You will only need to buy one key, even if you have 5 locks.
  • 3. All your house locks on 1 key – no need to have multiple keys for your home.
  • 4. Losing you keys – If you lose your keys you will only need to get one replacement key ( note most locksmiths recommend replacing the lock if you lose a key ).

This is why most businesses, offices and residential homes will use Keyed alike locks as it means having one key for two locks, or even one key for five locks.

Disadvantages:

Some are concerned keying alike your door locks may reduce the security of your property but this is simply not the case.

Can My Existing Padlocks be Keyed Alike?

It depends on the type of padlocks you have. Some locks are designed to be keyed alike whilst other are not.

You can either:

  1. 1. Buy padlocks in sets that are already keyed alike
  2. 2. Buy locks that have been pinned to a pre-made code that you can buy more of at anytime or
  3. 3. Make sure your padlocks have removable cores so you can change the key code.

What is the Cost of Keyed Alike Padlocks?

Keyed Alike padlocks are usually bought together when you need them, so the price will be included in the cost of the locks.

The price of having existing padlocks keyed alike may be more expensive than just purchasing already keyed alike padlock.

We recommend speaking to an MLA locksmith in your area for exact pricing.

The best time to have your locks keyed alike could be as follows:

  • Moved into a new house  – looking to change all the locks
  • Have lost your keys – locksmiths always recommend to change the locks when losing keys – so having your locks keyed alike at the time is a good idea )
  • Upgrading your existing locks – if your upgrading multiple locks to British Standard, Keying alike again can save you time in the future.

7. How much does it cost to Key Alike?

The cost all depends on the locks you have, if you cannot key alike your current locks then new locks may be required.
