Mitsubishi Locksmith Services in Dallas
ETACS immobilizer work — blade transponders on base trims, FAST-Key proximity fobs on the rest, programmed on-site.
Quick Answer
Yes — a mobile locksmith in Dallas can cut and program Mitsubishi keys for roughly $120–$200 for a blade transponder key, $160–$280 for a remote head key, and $250–$500 for a FAST-Key proximity fob, versus $700–$1,100+ all-in through a dealership once towing is added. All-keys-lost adds $75–$250, since the immobilizer has to be put into a learn state rather than copied from a working key. Dallas Locksmith Pros is mobile and 24/7 at (469) 896-4128.
Mitsubishi runs its body electronics and much of its security logic through the ETACS module — the Electronic Time and Alarm Control System — with the immobilizer validating the key's transponder against data shared with the engine computer. The lineup splits cleanly by trim: base Mirage, Outlander Sport and older Lancer trims use a blade transponder key through a conventional ignition cylinder, while higher trims carry Mitsubishi's FAST-Key proximity fob with push-button start. Dallas Locksmith Pros programs both on-site across Dallas, cuts blades to code from the VIN, and handles all-keys-lost calls without a tow, 24 hours a day.
Mitsubishi Key & Ignition Pricing in Dallas
Ranges current as of July 2026. Final price depends on model year, key type, and whether a working key still exists — confirmed on the phone before dispatch.

Mitsubishi Models We Service in Dallas
Mitsubishi Outlander
2014–2021Trim-split hardware — blade transponder on ES trims, FAST-Key proximity fob on SE and up; both authenticate through the same immobilizer and ETACS-era body electronics.
Mitsubishi Outlander
2022–presentCo-developed with Nissan and sharing the Rogue's platform generation, so key hardware and procedures follow the newer architecture — VIN check first, always.
Mitsubishi Outlander Sport
2011–presentLong production run with the same trim split throughout; base cars are turn-key transponder work, higher trims carry the FAST-Key fob.
Mitsubishi Eclipse Cross
2018–presentLaunched in the push-button era — FAST-Key proximity fob on most trims, with the emergency blade in the fob as the mechanical fallback.
Mitsubishi Mirage
2014–presentBudget hatch and G4 sedan; base trims kept the blade transponder key longer than almost anything else on the market, which keeps replacement costs at the low end.
Mitsubishi Lancer
2002–2017Turn-key transponder cars nearly across the board; high-mileage examples are our most common Mitsubishi ignition-cylinder wear calls.

About Mitsubishi Key & Module Systems
Mitsubishi's security architecture centers on the ETACS module — the Electronic Time and Alarm Control System — a body computer that has grown over the generations from a timer-and-alarm unit into the hub for locks, lighting, remotes and security functions. The immobilizer works alongside it: a transponder in the key head is read at the ignition barrel on turn-key cars, or a FAST-Key fob is authenticated through cabin antennas on push-button cars, and the result is checked against key data the engine computer has to agree with before a crank becomes a start. The practical consequence is the same as on other modern brands — cutting a blade or buying a fob online does nothing until the car is programmed to accept it — but Mitsubishi's procedures are well supported by independent tooling across the volume of the lineup, which keeps this work mobile and keeps you away from a tow truck. Hardware splits by trim more than by model.
A base Mirage or Outlander Sport runs a blade transponder key through a conventional cylinder; an SEL trim of the same year carries the FAST-Key proximity fob with push-button start and a hidden emergency blade. Older Lancers are turn-key transponder cars almost across the board, and the Eclipse Cross launched in the push-button era. One wrinkle worth knowing: the 2022-and-newer Outlander was co-developed with Nissan and shares its platform generation with the Rogue, so its key hardware and procedures follow that newer architecture — we treat those as VIN-check-first vehicles rather than assuming the older Outlander playbook applies. All-keys-lost is the job that separates equipped techs from parts-swappers.
With no working key present, the immobilizer has to be put into a learn state and its key data rebuilt before a new transponder or fob is accepted, which is why all-keys-lost carries a $75–$250 add-on over a simple spare. Mechanical wear is the other recurring theme: high-mileage turn-key Mitsubishis develop worn wafer stacks that make the key jiggle, bind, or refuse to return to OFF. A worn cylinder is frequently rebuildable and rekeyed to the key already on your ring for $90–$200; a finished one is replaced at $180–$400 and keyed to match. We do all of it at your location — driveways, parking garages and roadside — anywhere in the Dallas area.
Where the honest limit is
Most Mitsubishis from the mid-2000s through the current lineup are on-site work, including all-keys-lost. Where we stop short of promising is the 2022-and-newer Outlander generation, whose Nissan-shared platform brings newer security gating, and any car whose ETACS or engine computer has already been swapped or reflashed by someone else — those can need an extra authorization step we would rather confirm than discover in your driveway. Send us the VIN and model year and we confirm exactly what your Mitsubishi needs before we dispatch a truck.

Frequently Asked Questions
Yes, on the large majority of the lineup. Mitsubishi's immobilizer procedures are well supported by independent tooling, so we cut blades to code from the VIN and program transponders and FAST-Key fobs at your location. The 2022-and-newer Outlander runs a Nissan-shared platform with newer gating, so those cars get a VIN feasibility check before we dispatch.
A blade transponder key generally runs $120–$200 cut and programmed, a remote head key $160–$280, and a FAST-Key proximity fob $250–$500 including the emergency blade. All-keys-lost adds $75–$250 because the immobilizer has to be relearned from scratch. A dealer typically lands at $700–$1,100+ once towing and programming labor are included.
FAST-Key is Mitsubishi's proximity keyless system — the fob stays in your pocket, cabin and door antennas detect it, and the car unlocks at the handle and starts with a button press. It appears on higher trims while base trims of the same model year keep a blade transponder key, so two identical-looking Outlanders can take completely different keys. We confirm which system your VIN carries before quoting.
That is the immobilizer refusing to authorize the start, not a fuel or battery problem. The usual causes are a key that was never programmed to this car, a transponder that has failed, or lost synchronization after battery or module work. An immobilizer relearn runs $120–$280 when the key hardware is healthy, and we diagnose which case you have before selling you anything.
Yes, in most cases without a tow. We cut a fresh blade to code from your VIN, put the immobilizer into a learn state with no working key present, and program the new key — or pair a new FAST-Key fob on push-button cars. Budget the key price plus the $75–$250 all-keys-lost add-on, and have proof of ownership and photo ID ready, because we verify both on every all-keys-lost call.
Because the fob is only half the part. Every transponder key and FAST-Key fob has to be written into the vehicle's immobilizer before the car will start with it, and that programming happens at the vehicle, not at the seller. We can often program a customer-supplied fob if the part number and frequency genuinely match your VIN — we check that first, since a mismatched aftermarket fob is unprogrammable no matter who tries.
