Frequently Asked Questions

How much does key duplication cost?

Standard key copies cost $3-$10. High-security key copies cost $15-$50 and require authorization. Call (210) 348-3677.

Can you copy a "Do Not Duplicate" key?

Standard “Do Not Duplicate” stamped keys have no legal restriction — we can copy them. Patented restricted keyway keys (Medeco, Mul-T-Lock) require authorization.

How long does key duplication take?

Standard key copies take about 2-5 minutes.

Can you duplicate a broken key?

If both pieces are available, we can often use them to cut a new key. Otherwise, we can create a key by impressioning the lock.
