Mitsubishi Lancer Evolution Key Replacement

Lancer Evolution keys by generation

The Evolution X uses the same key hardware as the 2008-2017 Lancer. Depending on trim and options, a car has either a four-button remote-head key on the MIT3 blade with a Philips ID46 chip, or FAST-key, which works through request buttons on the doors and replaces the ignition key with a twist knob. The FAST-key fob holds an emergency blade for the driver's door and runs on a CR2032. We check which system your car has before ordering anything. Programming matches the regular Lancer: remote-head keys and FAST-key fobs are registered through the OBD-II port with a programmer and the security PIN, and the registration clears and relearns all keys. Used fobs must be unlocked before they will learn. For all-keys-lost, we decode the door lock, cut the blade or emergency insert, and register at least two keys on site.

US Evolution VIII and IX cars start with a transponder key: a plastic-head MIT3 key with a Texas 4D61 chip, sold by Ilco as the MIT14-PT. Keyless entry, where fitted, came as a separate remote that takes a CR2032 and pairs through the diagnostic connector. There is no smart key or push-button start, so every car has a normal ignition cylinder. A plain metal copy will open the doors but won't start the engine. Keys are registered through the OBD-II port with a programmer and the immobilizer PIN, and Mitsubishi's routine erases and relearns every key, so bring all of them. The separate remote pairs on board through the diagnostic connector without a programmer. For all-keys-lost, we decode the door lock, cut new keys on the 4D61 blank and register them at the car.

Mitsubishi key security

Mitsubishi's US key history splits into a handful of eras, and the model year usually tells us which one we're dealing with. Around 2000, the larger models got Texas Instruments transponders: the Diamante, Montero and Montero Sport on the MIT1 key, and the Eclipse and Galant on the MIT6 key, with the chip moving from 4D60 to 4D61 around the middle of 2001. Small cars such as the Mirage and the 2002-2007 Lancer generally kept plain cut keys, although the Lancer Evolution did not. Philips ID46 chips appeared on the redesigned 2004 Galant, remote-head keys followed in 2006, and the blade changed from the straight MIT6 to the shouldered MIT3 during the 2007 model year. The 2007 Outlander and 2008 Lancer introduced FAST-key, Mitsubishi's keyless operation system, which carried on through the Lancer Evolution X and the Outlander Sport. Later Mirage, Eclipse Cross and Outlander Sport smart keys are newer designs that need their own tool coverage, and the Nissan-based 2022-on Outlander uses an AES-encrypted fob. The Dodge Dakota-based Raider pickup follows Chrysler's Sentry Key rules instead.

Most Mitsubishi transponder keys and FAST-key fobs are registered through the OBD-II port with a programmer that supplies the vehicle's security PIN, which professional tools can often retrieve and dealers release by VIN to verified owners. On many models the registration routine clears every stored key and relearns only the ones present, so bring all the keys you want to keep. Separate keyless remotes from the early 2000s can usually be paired on board with a jumper across pins 1 and 4 of the diagnostic connector, but remote-head keys and smart fobs from 2006 onward need a programmer. Used Mitsubishi remotes lock to the first car they learn, so a secondhand one has to be unlocked or renewed before it will pair, and some newer fobs can't be reused at all. The 2022-and-later Outlander and Outlander PHEV follow Nissan-style procedures that may need a gateway bypass or a dealer step. We check your ID and registration before any of this.

All Lancer Evolution keys lost

If every key to your Mitsubishi is gone, the first job is a working blade. We decode the driver's door lock or cut from a key code the dealer releases by VIN with proof of ownership. Then the immobilizer PIN is obtained and new keys are registered at the car, at least two, which also drops the lost keys from memory. FAST-key and newer smart-key cars need a new fob plus its emergency insert, and remote-head keys need the blade cut and the buttons paired. Most turn-key and older FAST-key models are handled where they sit. Newer smart keys on some Mirage, Eclipse Cross and Outlander Sport builds, plus the 2022-and-later Outlander and Outlander PHEV, may need a dealer PIN or a dealer visit, and we tell you before you commit. Expect to show ID first.

1. Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Mitsubishi Lancer Evolution can be done on-site and bring the right key, so the first trip is the only trip.
2. Get into the vehicle without damage. If the car is locked, we open it with non-destructive tools such as an inflatable wedge and a long-reach rod, or by picking the door lock. Some vehicles need a careful approach to avoid triggering the alarm, which can interfere with programming later.
3. Originate a new key from the car. With no key to copy, the cuts come from the vehicle itself. We retrieve the key code through manufacturer channels where possible, or decode a door lock with a pick-decoder tool. Then we cut the blade on our code machine and confirm it turns the lock smoothly.
4. Program the key to the immobilizer. All-keys-lost programming often takes longer than adding a key, because the car has no trusted key to authorize the change. We follow the procedure your Mitsubishi Lancer Evolution requires, then confirm the engine starts and keeps running and the remote or keyless functions respond.
5. Erase missing keys and add a spare. Once the car starts, we remove the lost keys from memory wherever the system allows, so they can't start the engine if someone finds them. Making a second key during the same visit costs much less than a repeat all-keys-lost call down the road.

Dealer or mobile locksmith?

Dealers have one clear advantage: direct access to the manufacturer's own systems. Some newer vehicles tie key programming to online authorization that only a dealer can use, and certain all-keys-lost situations on specific platforms still require it. A good locksmith knows where those lines are. Where we can do the job, we use professional programming equipment that talks to the same immobilizer and keyless systems through the OBD-II port, and in many cases the result is identical: a properly registered key that starts the car. Where we can't, we can often still help by opening the vehicle, cutting a mechanical blade from code, or helping you gather what the dealer will ask for so that visit goes smoothly. For your Mitsubishi Lancer Evolution, ask us directly and you'll get a plain answer.

How the job works

1. Identify the exact key your Lancer Evolution uses. Every job starts with the VIN, the trim and a look at any key you still have. From those we confirm the keyway, the transponder or smart-key chip, the remote frequency, the FCC ID and the button layout. Two Mitsubishi Lancer Evolution keys that look identical can carry different electronics, so this step keeps the wrong part from ever reaching the car.
2. Verify ownership before any work. California holds licensed locksmiths responsible for knowing whose car they're making keys for. We record your name, the VIN and the plate on a work order. If you aren't the registered owner, you'll need the owner's written authorization along with your own photo ID before we begin.
3. Get the key code or decode the lock. A key is cut from a code, not a guess. When the factory code can be retrieved through manufacturer channels after ownership is verified, we use it. When it can't, we decode a door lock with a pick-decoder tool that reads the wafer positions without damaging anything, then work out any missing cuts.
4. Cut the blade on-site. Our van carries a code-cutting machine that handles both traditional edge-cut blades and the laser-cut, side-milled profiles common on newer keys. The blade is cut to the code, then test-fitted in a door lock and the ignition or emergency keyhole to confirm smooth operation before any programming begins.
5. Program the chip, remote or smart key. Programming tells the car's computers that the new key belongs to the vehicle. Transponder chips are added to the immobilizer, remote buttons to the body control module, and proximity fobs to the keyless system. If a step requires dealer-only access on your Lancer Evolution, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

What affects the price of a Lancer Evolution key

• The type of key. The biggest factor is technology. A plain mechanical key is a cutting job only. A transponder key adds a chip and programming. Remote-head and flip keys add a circuit board, and a proximity fob for a push-button Mitsubishi Lancer Evolution is the most involved of all, both in the part itself and in the programming.
• Factory or aftermarket parts. Some owners want an exact factory match; others just want a dependable key that starts the car. Both are reasonable choices. The part you pick changes the quote, so we lay out the options side by side, with the trade-offs in fit, button feel and long-term durability, before you decide.
• All keys lost or adding a key. Adding a key while a working one is in hand is the simpler job. With every key gone, we may have to open the car, decode a lock to originate the cuts, and run a longer programming routine, so all-keys-lost work takes more time and costs more.
• Blade style and cutting. The blade still matters on keyless cars, because the emergency insert has to fit the door lock. Cutting by code is standard for us. Decoding a door lock when no key or code exists adds time, and so does progressing any cuts the door lock doesn't show.

Lancer Evolution key types explained

• Transponder (chip) key. Transponder chips come in families, such as Texas Instruments 4C and 4D, Philips 46, Megamos 48 and the newer 128-bit AES types, and a Mitsubishi Lancer Evolution only accepts the one its immobilizer was built around. That's why a hardware-store blank that looks right often won't start the car. We match the blank to the vehicle's chip and keyway before cutting. One more practical note: the chip lives in the plastic head, and when that head cracks, the chip can fall out or shift away from the antenna. If the car starts some days and not others, a damaged head is a frequent reason, and replacing the key before it quits entirely costs less than an all-keys-lost visit.
• Remote head key. Remote-head keys take a beating. The rubber button pad wears through, the plastic housing splits at the seam, and the blade can snap right at the head after years of being used as a pry tool or hanging from a heavy key ring. When the electronics inside are still healthy, we can often move the circuit board and chip into a new shell and cut a fresh blade to your code, which keeps the existing programming intact. If the board is cracked or water-damaged, a new key is the honest answer. Either way, for your 2015 Lancer Evolution, we open the old key and show you what's broken before recommending anything.
• Key with separate remote fob. Pairing a separate remote to a 2015 Mitsubishi Lancer Evolution is a different job from programming the ignition key. Some vehicles accept new remotes through an on-board sequence of key turns and button presses; others need a scan tool connected to the OBD-II port. On many of them, entering remote programming mode clears every remote the car already knows, so any remote you want to keep has to be present and re-paired during the same session. Before we start, gather every remote that belongs to the vehicle. Leaving one in a kitchen drawer is a classic way to end up with a remote that quits the day after a new one is added.
• Smart proximity key (push-to-start). Making a new smart key is mostly a programming job. The fob has to match the vehicle's FCC ID, frequency and chip, and then the keyless system must be told to accept it, normally through the OBD-II port. Depending on the platform, that can mean entering a PIN, waiting through a timed security procedure, or on some newer vehicles, using manufacturer online access. When every key is lost, certain models need a module removed and read on the bench. For your Mitsubishi Lancer Evolution CZ4A (Evolution X), we'll tell you which of those applies, and if a step is dealer-only, you'll hear it before we drive out. The emergency blade hidden inside the fob is cut by code during the same visit.

Why a spare key pays for itself

• Some vehicles make it hard to add a key once you're down to one. Certain immobilizer systems let an owner program an extra key on-board only when two working keys are present, so a second key preserves the easy options for later and avoids a full reset.
• A spare turns a future all-keys-lost emergency into a simple add-a-key job. With one working key in hand, programming is quicker, and the chip or fob can often be paired without decoding locks or reading modules, which keeps the cost of a lost key far lower.
• Electronics fail without warning. A fob dropped on concrete, run through the washing machine or soaked at the pool can quit for good. With a second programmed key, that's an annoyance you fix on your own schedule, not a stranded car that needs attention today.

Tips from a mobile locksmith

• Make the spare before you need it. Adding a key while one still works is quicker and less expensive than starting from nothing, and it keeps the simpler programming options available. Good moments are right after buying the car, or as soon as one of your two keys goes missing.
• Photograph the back of your fob and any key tag that came with the car. The FCC ID, part number and key code printed there make ordering a replacement faster and more accurate. Store the photos somewhere you can reach from any device, not only on the phone that might go missing along with the keys.
• If your vehicle has a proximity key, think about where it sleeps at night. A fob hanging by the front door can sit within range of relay equipment used to open and start cars from outside. A drawer deeper inside the house, a signal-blocking pouch, or the fob's own sleep mode reduces that risk considerably.
• Never hide a spare key or fob on the outside of the car. Magnetic boxes in wheel wells and under bumpers are the first places a thief checks, and with a proximity fob, a hidden key can let anyone open the doors and drive away. Keep the spare at home or with someone you trust.

Common Mitsubishi key problems

• Remote-head keys on the 2006-2007 Eclipse, Galant and Endeavor came with either a straight MIT6 blade or a shouldered MIT3 blade depending on build date. Check which one your old key has before ordering, because the two are not interchangeable.
• Mitsubishi remotes and smart fobs lock to the first vehicle they're programmed to. A used one from a salvage yard or online seller has to be unlocked or reflashed before it will pair, and some newer fobs cannot be reused at all.
• Remote-head keys and smart fobs take different coin cells: the remote-head keys use a thin CR1620, while FAST-key and smart fobs use a CR2032. A cell of the wrong thickness may not make good contact, so read the old battery before buying.
• Key registration on many Mitsubishis wipes every stored key and relearns only the ones present. A spare left at home during the appointment stops working afterward, so gather every key you want to keep before we start.
• The 2007 Outlander used a one-year FAST-key fob, FCC ID OUCG8D-640M-KEY-N, that differs from the OUC644M-KEY-N fob used from 2008 on. Ordering by model name alone often brings the wrong part.
• Mirage hatchbacks built before about March 2014 use the same FAST-key fob as the Outlander, while later Mirage fobs are a different design. The build date on the driver's door-jamb label settles which one you need.
• Inland Empire heat drains fob batteries faster than the calendar suggests. On FAST-key cars, a key warning on the dash or a fob that only works up close usually means a weak CR2032, an easy fix before it strands you.
• Eclipse and Galant models built in 2000 and early 2001 use a Texas 4D60 key, while later 2001 cars use 4D61. A key stamped R on the blade is the early type and one stamped N is the later type, and the wrong chip will turn the locks but not start the engine.

Proof of ownership

Before we cut or program a key for any vehicle, we verify that you have the right to it. Please have two things ready: the current registration or the title, and a government-issued photo ID with a matching name. We also check that the VIN on those documents matches the VIN plate on the dashboard. If the registration is locked inside the car, that's fine; we open the vehicle first, check the paperwork in the glove box, and only then make the key. If something doesn't line up, we stop and sort it out before any key is made.
