How do I make a copy of an old (antique) key?

As a key and fob copying service, we occasionally have customers bring in antique or vintage keys, wondering if they can be duplicated. These keys often hold sentimental value, belonging to old homes, antique trunks, or family heirlooms. While we specialize in modern key and fob duplication, we thought it would be interesting to explore whether old keys can be copied and how to go about it.

Can Old Keys Be Duplicated?

Yes, old keys can sometimes be duplicated, but the process depends on the type of key and its condition. Unlike standard modern keys, which follow common key blank templates, antique keys—such as skeleton keys, warded keys, or barrel keys—require special attention.

How to Get an Old Key Copied

If you have an old key that you want duplicated, here are some options:

1. Check with a Specialty Locksmith – Not all key cutting shops will have the necessary blanks for antique keys, but specialized locksmiths or those with experience in older keys may be able to help.
2. Find the Right Key Blank – Some old keys can still be copied using modern blanks, but in many cases, a locksmith may need to modify an existing blank or order a specialty blank to match your key.
3. Hand-Filing for Precision – Some intricate keys, especially those with unique cuts, may require manual filing rather than a machine-cut duplication.
4. 3D Printing or Custom Fabrication – If your key is extremely rare and a blank isn’t available, some locksmiths or machinists can create a replica using 3D printing or metal casting techniques.
5. Bring the Lock – If the key is too worn or broken to copy directly, bringing the lock it fits into can sometimes help a locksmith recreate a working key from scratch.
