Auto Locksmith Service, Anywhere You’re Parked

Mechanical-only (pre-1995)

Basic cut key with no electronics. Cheap to duplicate at a hardware store. Still used on some commercial trucks and older vehicles.

Transponder (1995+)

Cut key with a chip in the head that the ECU authenticates. Must be programmed on-board with the correct diagnostic tool.

Remote-head transponder

Transponder key with built-in lock/unlock buttons. Same programming as a transponder plus remote-function pairing.

Proximity / smart key

Push-button start vehicles. The fob talks to the car via low-frequency signal. Programming requires specific equipment and often a physical backup blade cut to match.

Laser-cut / high-security

Used on many European and luxury vehicles. The cut itself is harder to duplicate without specialized equipment.

Mobile-app / digital key

Newest vehicles support phone-as-key via Bluetooth or UWB. Great when the phone works and the battery is charged; backup physical or fob key is still required.

Where the dealer wins

Where mobile locksmiths win

Key code from VIN

Many manufacturers store the original key cut as a numeric code indexed to the VIN. A licensed locksmith pulls this code through credentialed access, then cuts a fresh key blank to that code on a code-cut machine.

Lock decoding

When a VIN-based code isn’t available, the locksmith disassembles or reads the existing door or ignition lock, decodes the pin/wafer pattern directly, and cuts a key matching that decoding.

Impressioning

A specialized skill: using a soft blank and precise filing, the locksmith produces a working key by reading wear marks the blank receives when inserted into the lock. Slow but reliable on older vehicles.

Transponder synchronization

After the physical blade is cut, the chip in the key is programmed through the OBD-II port or through the immobilizer reset sequence specific to that vehicle.

All-keys-lost procedure

Newer vehicles have specific procedures for losing every key in the system. Some require a security-delay waiting period (often 10–40 minutes while the immobilizer accepts the pairing request).

Proximity-fob pairing

For push-button-start vehicles, the fob must be physically registered to the car’s receiver, which requires both the diagnostic tool and in some cases a token or credential from the manufacturer.

Rekey

Changing the internal pins of an existing lock so old keys stop working, but the hardware itself stays. Cheapest security update after a move, key loss, or roommate departure.

Key-alike

Rekeying multiple locks so one key opens all of them. Common setup for a single-family home’s front, back, garage, and side doors.

Master-key system

A hierarchy where one key opens every lock, sub-masters open scoped areas, and individual change keys open specific doors. Standard in commercial buildings and larger rentals.

Grade 1 / 2 / 3

ANSI/BHMA hardware grade. Grade 3 is builder-grade residential, Grade 2 is heavy residential / light commercial, Grade 1 is commercial. Higher grades mean more cycles and better forced-entry resistance.

Restricted keyway

A keyway that only authorized dealers can cut keys for. Prevents employees or tenants from making hardware-store copies. Required for meaningful key control.

Bump key

A specially cut key that exploits a rapid impact to pop standard pin-tumbler locks open. Legitimate tool for licensed locksmiths, also an entry method criminals use. High-security cylinders defeat it.

Non-destructive entry

Opening a lock without damaging it — picking, bumping, impressioning, or using bypass tools. Professional standard. Drilling is reserved for genuinely damaged or high-security locks where picking fails.

Transponder key

A car key with an embedded chip that authenticates to the vehicle’s immobilizer. Required for most vehicles built since 1995. Cutting alone isn’t enough — the chip must be programmed to the specific car.

Proximity fob

Push-button-start vehicle key that communicates with the car via low-frequency radio. Programming requires a diagnostic tool and often a physical backup blade cut to match.

Deadbolt

A lock with a bolt that extends into the door frame and can only be retracted by turning a key or thumbturn (not by spring pressure like a latch). Primary exterior-door security on most residential installs.

IC core

Interchangeable core — a removable cylinder that can be swapped in 30 seconds with a specialized control key. Heavily used in commercial and multifamily settings for fast rekey on turnover.

Mortise vs. cylinder

Mortise locks fit into a pocket cut into the door edge; cylinder locks mount through a bore hole. Mortise is heavier-duty and more common on commercial; cylinder is the residential standard.
