A blank key is an uncut key. It has the right shape and keyway (the groove pattern along the blade) for a type of lock, but it doesn’t yet have the unique cuts that match your specific lock.

• Common uses: Duplicating house or office keys.
• Types you’ll see: Standard residential blanks (often labeled with codes like KW1 or SC1), mailbox and padlock blanks, tubular and skeleton styles, and automotive transponder blanks.
• Materials & designs: Brass or nickel-plated options, plus decorative designs.

To work in your lock, a blank needs to be cut to match your existing key. Always duplicate keys only for locks you own or have permission to copy.

An uncut blank typically won’t operate a lock. Here’s why:

• No matching cuts: Even if the blank slides into the keyway, it won’t lift the pins (or wafers) to the right heights, so it won’t turn.
• Keyway mismatch: If the groove pattern doesn’t match your lock, the blank may not insert at all.
• Potential damage: Forcing a blank can wear or damage your lock and the key.
• Vehicles: Many automotive keys also include chips; they require both accurate cutting and programming.

To use a blank, match the keyway code (e.g., KW1 or SC1) and have it cut by a key-cutting service. Test gently; results can vary depending on lock condition and cut quality.

It depends on the cutting service available at your local store.

• Self-service kiosks: Some kiosks only cut blanks they dispense, while others may accept customer-provided blanks. Availability varies by location.
• Before you go: Bring a working original key and ensure your blank matches the correct keyway code and is in good condition.
• Limitations: High-security, restricted, or damaged keys may be declined. Automotive transponder keys often need specialized cutting and programming.

Check your store’s services and kiosk availability online or call ahead. If your blank isn’t compatible with the in-store option, a professional locksmith may offer alternatives.

You can duplicate a house key using a blank that matches your lock’s keyway.

1. Confirm permission: Only copy keys for locks you own or have authorization for.
2. Identify the code: Look for a keyway code on your key head (e.g., KW1 or SC1) and choose a matching blank.
3. Cut the key: Use an in-store self-service kiosk or a professional cutting service. Copy from a good, working original for best results.
4. Test carefully: Try the new key gently; a light lubricant can help if it feels stiff.

These steps can help, but cutting accuracy and lock wear can affect results. If a key doesn’t work smoothly, a professional recut may be helpful.

Match the blank to your existing key and lock type.

• Check the code: Look for a keyway code stamped on your key head (common examples include KW1 or SC1). Use a blank with the same code.
• Match the grooves: The side grooves and blade length must align with your lock’s keyway.
• Know the application: Standard residential, mailbox/padlock, tubular, skeleton, and automotive transponder keys each use different blanks.
• Decorative options: Painted or themed blanks work like standard ones if the keyway code matches.

If you’re unsure, bring your original key to compare profiles at the display or consult a store associate. Availability varies by location and lock type.
