Residential Key Duplication FAQs

Common questions about our Residential Key Duplication services

Basic house key duplication typically costs $2-$5 per key at our shop, which is competitive with hardware stores but with much better quality control. More complex keys like high-security or decorative keys may cost slightly more depending on the blank required. We provide upfront pricing before any work begins, so you’ll know exactly what to expect. Unlike some competitors, we don’t have hidden fees or surprise charges. The price you’re quoted is the price you pay, and most standard residential keys are ready in just a few minutes.
High-security keys marked “Do Not Duplicate” require special authorization and equipment that we have in our shop. We’ll need to verify your ownership of the key and may require additional documentation like proof of residence or business ownership. These keys are designed for enhanced security, so the duplication process is more involved than standard keys. We handle these requests professionally and can usually complete them the same day, though they may take longer than basic key cutting due to the verification process.
Most standard house keys are cut and ready in just a few minutes while you wait. We don’t require appointments for basic residential key duplication – just walk in during our business hours Monday through Friday. More complex keys like high-security or antique keys may take 10-15 minutes depending on the blank selection and cutting requirements. We’ll give you an accurate time estimate when you bring your key in, and you’re welcome to wait in our shop or browse our other locksmith products and services.
Worn keys are actually one of our specialties after 100+ years in business. We can often work with keys that big box stores would turn away because our technicians have the experience to read even heavily worn key cuts. If your original key is too damaged to duplicate directly, we may be able to work from your lock itself to create new keys from scratch. We’ll examine your key and let you know your options before starting any work, and we’ll be honest about whether duplication is possible or if you need a different solution.
Absolutely. Every key we cut is tested in our shop before you take it home to ensure it works smoothly in your locks. If you have any issues with a key we’ve duplicated, bring it back and we’ll make it right at no charge. Our four generations of experience means we stand behind our work completely. We use quality blanks and precision equipment, so problems are rare, but if something isn’t perfect, we’ll fix it. That’s the difference between working with a family business versus an automated kiosk.
Yes, unusual and antique keys are exactly the type of challenges we love to tackle. Our shop stocks a wide variety of key blanks, including many that aren’t available at hardware stores or big box retailers. We’ve been cutting keys since the late 1800s, so we’ve seen just about every type of key and lock combination imaginable. Bring your antique key in and we’ll examine it to determine if we can duplicate it. Even if it requires special ordering a blank, we can usually help you get the spare keys you need for your unique locks.
