Why Rekeying Your Locks Might Be Better Than Replacing Them

Moving into a new home? Lost a key? Updating your security system? If your answer is all of the above, you don’t necessarily have to change the lock. That’s right, there are actually affordable lock solutions—rekeying!
Rekeying is a smart alternative to keep your property secure without demolishing the entire lock mechanism. You only have to tweak the internal lock system and use a new key, hence the word rekeying.
Keep reading and explore further the ins and outs of lock rekeying and whether or not you can do it yourself.
What Is Rekeying a Lock?
Rekeying is simply changing the internal pins of the lock so the old keys no longer work. In other words, you keep the same lock hardware with a new key.
This is a quick, noninvasive and cost-effective way to enhance security when losing a key or moving out.
Rekeying vs. Replacing: What’s the Difference?
As mentioned, rekeying is the process of changing your existing lock’s internal system so it operates for a different key.
On the other hand, replacing is exactly how it sounds: swapping your old lock for a new one.
Check out this table for a side-by-side comparison of the process, costs and outcome between the two:
Feature | Rekeying | Replacing Locks |
Process | The pins are rearranged of your existing lock so it works with a new key. | Replacing the entire lock entirely for a new one |

Hardware | Uses the old, existing hardware | Requires new hardware |
