Broken Key Extraction

Keys break for a handful of predictable reasons: metal fatigue from years of daily flexing, a worn or misaligned lock cylinder that forces the user to apply side-loading torque, extreme cold that makes both the key blank and the cylinder housing less forgiving, or a key that was cut on a worn duplicator and never quite fit right to begin with. Denver's freeze-thaw cycles — especially brutal in January when temperatures can swing 40 degrees in a single day — accelerate wear on both keys and lock cylinders far faster than in milder climates. Once a key snaps, whatever remains inside the cylinder can rotate slightly or press against the tumblers, making it even harder to reach.

The type of lock housing the broken fragment determines the tools, the technique, and the time required for a successful extraction. A mortise lock — the rectangular cartridge-style lock body common in older Denver commercial buildings, hotels, and pre-war multifamily properties along streets like East 17th Avenue — sits deeper in the door and often requires the cylinder to be partially removed before the fragment can be retrieved cleanly. A standard door knob lock offers a narrower keyway and less working room. An automotive ignition cylinder is pressurized by a return spring and may have the fragment seated against a wafer tumbler, adding complexity. Our mobile technicians are trained specifically across all three environments and arrive with the right extraction kit for the situation described when you call.

Residential extraction calls — whether from a single-family home in Stapleton, a condo in LoHi, or a rental property near the University of Denver — typically involve pin-tumbler door knob locks or deadbolts. The goal is always to retrieve the fragment intact, inspect the cylinder for damage, and test the lock before we leave. If the cylinder was already worn before the key broke, we'll let you know so you can decide whether a rekey or cylinder replacement makes more sense than leaving a compromised lock in service.

Commercial extraction jobs add a layer of complexity that makes professional handling especially important. A broken key inside a mortise lock on a storefront or office suite isn't just an inconvenience — it's a security gap and a potential liability. Our commercial locksmith team handles mortise lock extraction with the same damage-free priority, but we also carry replacement cylinders for common commercial hardware so a single visit can resolve both the extraction and any follow-up hardware service. For vehicle owners, our automotive extraction service covers car, truck, and SUV ignition cylinders as well as door lock cylinders — and yes, that extends to situations where the ignition itself may need service after the fragment is removed.

When you call (704) 850-6756, a live team member answers — not voicemail, not an answering service that routes a ticket. You'll describe the situation: what type of lock, whether the key is partially visible, your location in the Denver area, and whether the lock was functioning normally before the break. That information lets the dispatcher route the nearest qualified technician to you and give you an accurate arrival estimate. Denver traffic along I-25 or I-70 during peak hours is a real factor, and we account for it honestly rather than quoting a travel time we can't keep.

Once the technician arrives, they'll assess the lock in person — checking how deep the fragment is seated, whether the cylinder has rotated, and whether the lock housing shows any pre-existing damage. You'll receive a confirmed, up-front price before any tool touches the lock. The factors that shape that price include the lock or vehicle type, the depth and position of the fragment, any parts needed if the cylinder requires replacement, your location within the service area, and the time of day. There are no hidden charges added after completion. If you're dealing with a commercial property on a tight timeline, let us know — we treat emergency calls with the urgency they deserve, around the clock.

Once the broken key is out, the job isn't necessarily finished. If the extraction revealed a worn cylinder, damaged tumblers, or a lock that was already due for service, our technician will walk you through the options — which may include rekeying the existing cylinder, replacing just the cylinder, or upgrading the entire lock assembly. A common question is whether a lock can be rekeyed without the original key, and the answer is yes: a skilled locksmith can rekey a cylinder by picking or decoding it first, then setting the new key cuts. You don't need to have the working key in hand for us to change the combination. Similarly, if you've lost all copies of your car key and need a new one made from scratch, our automotive team can often generate a working key from the vehicle's VIN data and door code, even without a surviving original — though modern transponder keys and push-button fobs require programming in addition to the physical cut. Call (704) 850-6756 any time to confirm what's possible for your specific vehicle make and model.
