Can a Locksmith Make a New Key From a Lock?

The most direct approach is lock decoding. A trained technician removes the lock cylinder — whether that is a door knob lock, a deadbolt, or a mortise lock — and reads the height of each internal pin or wafer. Every pin position corresponds to a cut depth on the key blade. Once those depths are measured with a caliper or decoded with a specialized tool, the locksmith programs that information into a key-cutting machine and mills a fresh key in minutes. No guessing, no trial-and-error — it is a precise mechanical read of what the lock itself already contains. The other approach is code-cutting. Vehicles and many commercial locks are manufactured with a bitting code on file. For a car, the VIN links to the factory key code, allowing a locksmith to cut a correct key without ever touching the lock cylinder. For a commercial building with a Schlage or similar master-key system, the managing locksmith typically holds those codes on record. Both methods are legitimate, professional, and fully traceable — ownership verification is always part of the process before any work begins.

Impressioning is a third, slightly older technique worth knowing about. The locksmith inserts a blank key into the lock and applies rotational pressure, then reads the tiny marks the pins leave on the blank. After carefully filing the blank to match those marks and repeating the process, a working key emerges. It takes more time and skill than digital decoding, but it leaves the lock completely intact and is especially useful on antique or unusual lock profiles where modern decoding tools do not fit. You will sometimes encounter this method on vintage Richmond Craftsman homes with original hardware that nobody wants to replace.

Not every lock is equally straightforward to key from scratch, and the type of lock in your door is the single biggest factor shaping how the job gets done — and what goes into your final quote. A standard door knob lock or a basic deadbolt has a relatively simple pin-tumbler cylinder that most decoding tools handle quickly. A mortise lock is a different story. Mortise locks are the large, boxy mechanisms set into a routed pocket inside the door edge, common in older Richmond apartment buildings, Victorian-era homes near Point Richmond, and most commercial storefronts. They often combine a latch, a deadbolt, and sometimes a privacy turn all in one housing. Decoding a mortise lock cylinder correctly requires a technician who understands its specific internal geometry — the wrong approach can damage a mechanism that may be decades old and irreplaceable.

This is why our commercial locksmith and residential locksmith work both start with a visual assessment before any tools come out. A qualified technician identifies the lock brand, the keyway profile, and whether the cylinder can be removed without disturbing the rest of the hardware. If you are managing a multi-unit property on Cutting Boulevard or a retail space near the BART station, the stakes of a damaged mortise lock are high — a broken mechanism can mean an unsecured door overnight. Calling an experienced locksmith who specifically understands mortise lock service is the right move, not a general handyman or a hardware-store key kiosk.

Lost your only car key in the Bay? Automotive key replacement is one of the most common calls we handle across the Richmond area, and it is also one of the most misunderstood. Modern vehicle keys — whether a transponder key, a laser-cut (sidewinder) key, or a smart proximity fob — cannot simply be duplicated at a hardware store. The physical cut is only half the equation; the electronic chip inside must be programmed to match your car's immobilizer system, or the engine will not start even if the key turns the ignition.

Here is the legitimate path: our automotive locksmith technician pulls your VIN, verifies ownership with your registration and ID, retrieves the factory key code, cuts the correct blade profile, and then programs the transponder using OBD-II diagnostic equipment or a direct bypass procedure depending on the vehicle. For most makes — Toyota, Honda, Ford, GM, Hyundai — this can be done roadside, right where you are stranded, without towing the car anywhere. The factors that shape your final quote include the vehicle make and model, the key type (basic transponder versus a push-button smart key), and the time of day. We confirm an exact price before we start, so there are no surprises when the job is done. If you are stuck right now, call (510) 930-3035 and we will dispatch a mobile technician to your location.

Home lockouts are the obvious scenario, but there are several others where a locksmith needs to produce a key without any original. Estate situations are common — a family member passes away and no one can locate keys to the home or to a standing floor safe. Rental property turnovers are another: a tenant leaves without returning every copy, and the landlord needs to verify the lock is re-secured before the next resident moves in. In both cases, the right answer is not to break the lock or drill it out. A skilled technician can decode the existing lock, cut a new key, and — if desired — rekey the lock at the same visit so the old copies no longer work.

Safe locksmith services follow similar logic. Whether you have a fire-rated document safe bolted to the floor of a home office or a larger commercial safe in a Richmond business, losing the combination or key does not always mean destructive entry. Many safes can be opened through manipulation or by reading the lock mechanism's bitting, then re-coded or re-keyed to restore full security. Rekeying a residential lock — which involves replacing the internal pins so the old key no longer works while a new key does — is often the most cost-effective security upgrade after any key-loss event. How do you rekey a lock? Professionally, it means pulling the cylinder, swapping the driver and key pins to a new combination, and cutting a matching key. It is not the same as changing the lock hardware entirely, and understanding that difference (what does it mean to rekey a lock versus how to change a lock) can save you from paying for a full hardware replacement when a simple rekey is all that is needed.

If you are locked out of your home, car, or business in the Richmond area, the first practical steps are straightforward: check every door and window you know to be accessible, call a trusted neighbor who may hold a spare key, and confirm you are in a safe, well-lit location. Do not attempt to force a door or window — beyond the physical risk, a forced entry on your own property can damage the frame in ways that cost significantly more to repair than a professional lockout service. There is no safe DIY equivalent to what a professional locksmith does when decoding a lock or cutting a key from scratch, and any technique that bypasses a lock without the proper credentials is outside the scope of what we cover here.

What should you ask a locksmith before hiring? First, confirm they will verify your identity and ownership before touching any lock — that is standard professional practice and protects you as much as it protects the property. Second, ask for a confirmed price before work begins, not an estimate after. Third, ask whether the technician is experienced with your specific lock type — a mortise lock on a 1920s Point Richmond home is not the same job as a Kwikset deadbolt on a new construction in San Pablo. Our team answers all three of those questions clearly every time.

We never begin work until you have approved the quote.

One of the most common questions we hear — alongside can a locksmith make a new key from a lock — is how much does a local locksmith charge for this kind of work? The honest answer is that the price varies based on several real factors, and any locksmith who quotes a flat number before seeing the job is guessing. Here is what actually drives the cost: the lock type matters most — a basic door knob lock rekey is a simpler task than decoding and cutting from a commercial mortise lock with a restricted keyway. For automotive work, the vehicle make, model year, and key technology (basic transponder versus a proximity smart key) each affect the labor and parts involved. Time of day is a factor on emergency calls — 3 a.m. service requires a technician to respond immediately and that is reflected in the quote. Travel distance from our base in the Richmond area plays a minor role on calls at the edge of our service territory.

What should not vary is the process: you receive a confirmed price before we begin, not an invoice surprise at the end. We do not add hidden fees for mileage, after-hours dispatch, or tool usage. What the quote covers is what you pay. If you want an accurate number for your specific situation — a mortise lock on a Commercial Street storefront, a transponder key for a 2018 Toyota Camry, a safe that has not been opened since the previous owner — the fastest path is a quick call to (510) 930-3035. We can often give you a confident range over the phone once we know the lock type and your location, and we confirm the final number on arrival before touching anything.
