High-security key duplication requires more precision than standard keys, so the process takes additional time. However, we can typically complete your order during your visit to our shop.

Standard residential key duplication is very affordable—typically much less than you’d expect. Exact pricing depends on key type and required blank, but we maintain competitive rates with other local locksmith services.
High-security and specialty keys cost more due to specialized blanks and advanced cutting techniques, but we’re still significantly less expensive than dealer or manufacturer pricing.
We provide clear, upfront pricing before beginning any work, so you know exactly what to expect. Multiple copies of the same key qualify for quantity discounts.

Our experience with vintage hardware means we understand older lock mechanisms and can often create functional keys even when originals are worn or damaged.
When we don’t have the right blank in stock, we can usually source it or modify existing blanks to work with vintage locks. Sometimes this requires custom solutions, but that’s exactly the type of challenging work we’ve specialized in for generations.
