Is It Cheaper to Copy or Replace a Key?

This is a common question, and to answer it shortly: it’s almost always cheaper to copy a key than to replace it. But there are a few situations where replacement is the only option. Let’s walk through it properly in today’s blog post.

Copying a Key vs Replacing a Key: What’s the Difference?

Copying a key means you already have a working key and just need an extra one made.
Replacing a key usually means the original is lost, damaged, or no longer accessible, and a new one needs to be issued.

That difference alone is what drives most of the cost gap.

Why Copying a Key Is Usually Cheaper

When you copy a key:

The original key already exists
No locks need to be changed
No system updates are required
The process is quick and straightforward

For standard keys, copies are inexpensive. Even for more specialized keys or key fobs, copying is typically far less expensive than a full replacement through a landlord or building management.

This is why many people choose to make copies in advance for roommates, family members, or backups.

Why Replacing a Key Costs More

Replacing a key often involves more than just cutting a new one.

Depending on the situation, replacement may include:

Lock changes or rekeying
Issuing a new key or fob through building management
Administrative or security fees
Waiting time

In rental buildings or condos, replacement fees can add up quickly, especially for key fobs or high-security keys.

When Replacement Is the Only Option

There are cases where copying isn’t possible:

The original key is lost and no copy exists
The key or fob has been deactivated
The key is patented or restricted and requires authorization
The lock or access system has been changed

In these situations, replacement is unavoidable, even though it costs more.

Final Thoughts: Is It Cheaper to Copy or Replace a Key?

If you’re deciding between copying or replacing a key, the cost difference is clear: copying is cheaper whenever it’s an option.

As long as you have a working key or fob, making a copy is usually faster, easier, and more affordable than going through a full replacement process later.
