Can You Rekey a Lock Without the Original Key?

You moved into a new place off Colfax Avenue, inherited a house in Washington Park, or simply lost your house keys somewhere between the RTD light rail and your front door — and now you're staring at a lock you're not sure is secure. The good news: you do not need the original key to rekey a lock. A trained locksmith can disassemble the cylinder, replace the internal pins, and set your lock to respond to a brand-new key — all without the old one ever showing up.

front door lock key — Trusted Denver Locksmith

You moved into a new place off Colfax Avenue, inherited a house in Washington Park, or simply lost your house keys somewhere between the RTD light rail and your front door — and now you're staring at a lock you're not sure is secure. The good news: you do not need the original key to rekey a lock. A trained locksmith can disassemble the cylinder, replace the internal pins, and set your lock to respond to a brand-new key — all without the old one ever showing up.

This guide walks you through exactly how that process works, what it means for your home's security, when rekeying makes more sense than a full lock replacement, and what to expect when you call a professional locksmith Denver team to handle it for you.

Frequently asked questions

Can you really rekey a lock without the original key?+

Yes — and it is one of the most common jobs a professional locksmith handles. Without the original key, the technician uses specialized tools to remove the lock cylinder non-destructively, extracts the existing pins, and installs a new pin set matched to a freshly cut key. The lock body and hardware stay in place; only the internal code changes. The process works on standard deadbolts, door knob locks, and mortise locks alike.

Can a locksmith make a key for my car when I have lost all the copies?+

Absolutely. A trained automotive locksmith can decode your vehicle's lock mechanically or through the onboard system and cut a new key — including transponder and smart keys — without any existing copy. The process varies by make, model, and year, and some newer vehicles require dealer-level programming equipment that our mobile team carries. Ownership verification is required before any automotive key work begins. Factors that affect your final quote include the vehicle type, key technology involved, and time of day.

What payment methods do you accept?+

We accept major credit and debit cards, cash, and electronic payment options. When you call to schedule or request emergency service, our team will confirm accepted payment methods for your specific situation. We always provide an exact up-front quote before any work begins, so you know the full amount before you commit.
