Mitsubishi Key Replacement, Key Fob Programming & Smart Key Service
From older transponder blade keys to today's FAST proximity smart keys, we cut and program Mitsubishi keys and fobs at your location across Palm Beach County.
Mitsubishi keys have moved through a few distinct systems, from early transponder blade keys to switchblade flip keys with an integrated remote and today's FAST proximity smart keys on push-to-start trims. Each system needs a different blank, chip, and programming approach, so identifying the year and whether your Mitsubishi is turn-key or push-to-start is the first step in any key job.
Our mobile techs handle the most common Mitsubishi models on the road in Palm Beach County, including the Outlander, Outlander Sport, Eclipse Cross, Mirage, and Mirage G4. Whether you have lost every key or just want a spare cut from a working one, we cut and program curbside and tell you the price before we start.
Because we do not keep verified factory key codes for every Mitsubishi trim, we confirm the exact key by the VIN or the original fob before we cut or order. That keeps the job honest and avoids surprises in your driveway or parking lot in West Palm Beach.
Mitsubishi models we service

Mitsubishi key types by generation
Mitsubishi keys changed significantly from one era to the next. The right blank, chip, and programming path depend on the year, trim, and ignition type, which is why we ask for the details before selecting a key.
Mid 2000s to early 2010s: transponder blade keys
Many Mitsubishi models in this era used a bladed transponder key that engages the immobilizer. A blade that fits the lock still will not start the engine unless the chip is programmed to the vehicle.
Early to mid 2010s: switchblade flip keys with remote
Mitsubishi rolled out switchblade flip keys with an integrated lock and unlock remote on many trims. These still rely on a transponder for the immobilizer and are programmed to the vehicle.
Mid 2010s to present: FAST proximity smart keys
Push-to-start Mitsubishi models use FAST proximity smart keys with a mechanical emergency blade hidden in the fob. Replacing a lost proximity fob requires programming to the vehicle, and all-keys-lost situations can need extra time.
Mitsubishi key data by model
Verified blank, chip, and FCC references are marked accordingly. Where a value depends on trim, button count, or production date, confirm it from the original key, a VIN lookup, or a supplier catalog before cutting or ordering.
Data is drawn from professional locksmith key references. It is a starting point for identification, not a guarantee for your specific vehicle.
Mitsubishi Outlander Key Replacement
The Outlander is the Mitsubishi we make keys for most often in the county. Its key system changed across generations, so the year and whether it is turn-key or push-to-start decide the blank and fob.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2007-2013 | Transponder blade key | Confirm the exact keyway and blade from the original key. | Transponder immobilizer; confirm the exact chip from the original key. | FCC ID varies by year and market; confirm from the original key or the VIN. | OBD programming where supported; all keys lost may need extra time. | Mechanical blade cut to the door and ignition lock. | Confirm with original fob |

- •Tell us if you press a button to start or twist a key so we bring the right proximity fob or flip key.
Mitsubishi Outlander Sport Key Replacement
The Outlander Sport (sold as the RVR in some markets) splits between turn-key and push-to-start trims, so confirming the ignition type matters before we cut.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2011-2019 | Flip key or transponder blade key by trim | Confirm the exact keyway and blade from the original key. | Transponder immobilizer; confirm the exact chip from the original key. | FCC ID varies by year and market; confirm from the original key or the VIN. | OBD programming where supported; confirm by VIN. | Mechanical blade cut to the door and ignition lock. | Varies by trim |

Mitsubishi Eclipse Cross Key Replacement

| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |

- •If your Eclipse Cross uses a button to start, it is a proximity smart key; bring the original fob so we match the correct one.
Mitsubishi Mirage Key Replacement
The Mirage hatchback is an economy model where base trims often use a simple bladed transponder key while higher trims add a flip key or proximity fob, so the trim decides the key.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|
| 2014-2019 | Transponder blade key or flip key by trim | Confirm the exact keyway and blade from the original key. | Transponder immobilizer; confirm the exact chip from the original key. | FCC ID varies by year and market; confirm from the original key or the VIN. | OBD programming where supported; confirm by VIN. | Mechanical blade cut to the door and ignition lock. | Varies by trim |

- •Base Mirage trims may not include a remote at all; tell us whether your key has lock and unlock buttons so we bring the right one.
Mitsubishi Mirage G4 Key Replacement
The Mirage G4 is the sedan version of the Mirage and shares its key history, splitting between bladed keys, flip keys, and proximity fobs depending on the trim and year.
| Year range | Key type | Ilco / keyway | Chip / system | FCC / OEM | Programming | Emergency / service key | Source confidence |
|---|---|---|---|---|---|---|---|

Common Mitsubishi key problems
- •Worn transponder blades that turn the lock but no longer start the engine reliably.
- •Lost or water-damaged FAST proximity fobs after a day at the beach or on the water.
- •All-keys-lost situations on newer push-to-start models that need extended programming time.
- •Buttons that stop responding on switchblade flip keys while the blade still works.
- •Confusion between turn-key and push-to-start trims of the same model year.
- •Flip-key hinges that crack or wear out after years of daily folding and unfolding.
Mitsubishi programming notes
- •Adding a spare to a vehicle that already has a working key is faster and cheaper than an all-keys-lost job.
- •All-keys-lost programming on newer Mitsubishi models may need dealer-level or advanced equipment, which adds time.
- •Proximity fobs are programmed to one specific vehicle and cannot be moved to another Mitsubishi.
- •We confirm the exact key by the VIN or original fob before cutting or ordering, since we do not keep verified codes for every trim.
- •If a Mitsubishi shares engineering with a partner brand, we still program it to your specific VIN rather than assuming one part fits all.

Mitsubishi Key & Fob FAQs
Can you make a Mitsubishi key if I lost all of them?
Yes. We generate and program a new key from your vehicle, though all-keys-lost jobs on newer push-to-start Mitsubishi models can take longer because of the added security access required.
Do you program Mitsubishi FAST proximity smart keys?
Yes. We supply and program proximity smart keys for push-to-start Outlander, Eclipse Cross, and other trims, and we cut the mechanical emergency blade hidden in the fob.
Is my Mitsubishi turn-key or push-to-start?
Both exist across these models. If you insert and twist a key it is turn-key; if you press a button to start it is proximity. Tell us which so we bring the right key.
What does it cost to replace a Mitsubishi key?
It depends on the year and whether it is a transponder key, a flip key, or a proximity fob. We give you an up-front price over the phone before we head out.
Can you cut a spare Mitsubishi key from my working one?
Yes, and a spare made while you still have a working key is the cheapest key you will ever buy. We cut and program it on the spot.
Do you come to my home or job site for a Mitsubishi key?
Yes. We are fully mobile and come to your home, workplace, or wherever the vehicle is parked in Palm Beach County.
My Mitsubishi key turns but won't start. What's wrong?
The chip in the key talks to the immobilizer. If the blade is fine but the engine cranks without starting or shows a security light, the transponder may have failed and the key needs reprogramming or replacement.
What information do you need to make a Mitsubishi key?
The year, model, VIN, whether it is turn-key or push-to-start, and proof you own the vehicle. A photo of your existing key helps too.
Do you replace Mitsubishi flip keys where only the buttons died?
Yes. If the blade still works but the lock and unlock buttons stopped, we can replace and program a new switchblade flip key.
Does the new Outlander use a Nissan-style key?
The newer Outlander shares engineering ties with Nissan, but we always confirm the exact fob by your VIN and program it to your specific vehicle rather than assuming one part fits every trim.
Are aftermarket Mitsubishi keys reliable?
Quality varies. We carry keys and fobs we trust to program and hold up in the Florida climate, and we will tell you honestly when an OEM fob is the better choice.
