A house key is a shaped piece of metal that lines up with the pins inside your door lock so it can turn and open. On our site, you’ll see two forms:

• Key blanks: Uncut keys that match a specific lock profile and need to be cut to your existing key.
• Cut keys: Already shaped to fit a particular lock (often done by a service).

Blanks come in different profiles and styles, including single- or double-sided and decorative finishes. Once a compatible blank is precisely cut, it functions like a regular house key.

Start by matching the blank to your current key and lock. A quick approach:

1. Check the code: Many keys have an alphanumeric keyway code stamped on them—choose a blank with the same code.
2. Compare the shape: Match the grooves, shoulders, and tip to your existing key.
3. Confirm the sides: See if your key has cuts on one side or both.
4. Pick a finish/design: Decorative options can help with identification without changing functionality.
5. Plan for spares: Multipacks are handy if you need backups.

If your lock uses a restricted or specialty profile, duplication options may be limited; a local key-cutting service can verify compatibility.

Several factors can influence the overall cost of key copies:

• Blank type: Standard blanks generally cost less than specialty designs or heavy-duty materials.
• Quantity: Making multiple copies at once can reduce per-key cost in some cases.
• Cutting service: Fees vary by provider, equipment, and location.
• Complexity: Restricted or specialty key profiles may need authorization or special tools.
• Add-ons: Extras like cases or wrist lanyards are optional costs.

Some shoppers buy compatible blanks online and then pay only for cutting. Actual pricing and availability vary by area and service provider.

Worn or bent keys can be unreliable to copy. These tips can help:

• Use the best original: Duplicate from the least-worn spare if possible.
• Avoid forcing bends: Repeatedly straightening a warped key can weaken it.
• Consider pro help: A professional may be able to assess the lock and cut a more accurate copy; results can vary.
• Check the lock: If a key sticks, the lock might need cleaning, maintenance, or replacement.
• Protect new copies: Store a spare and use a case to reduce wear.

A quality blank and precise cutting may improve performance, but the condition of the original key and lock matters.

Decorative blanks are made to be functional once properly cut to match your lock. Here’s what to expect:

• Function: When the profile matches and the cut is accurate, they work like standard keys.
• Materials: Most use common key metals (such as brass); finishes and prints vary.
• Wear: Color or coatings can show surface wear over time with heavy use.
• Identification: Distinct designs make it easier to spot the right key quickly.
• Care: A pouch or key case can help protect the finish.

Choose a design you like, but always confirm it matches your keyway and side configuration.
