2015 Mitsubishi Lancer Evolution Key Replacement

2015 Lancer Evolution key specs

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.

What's specific to the 2015 Lancer Evolution

2015 was the final model year of the Lancer Evolution CZ4A (Evolution X). Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2015 Mitsubishi Lancer Evolution matches a 2008. At roughly 11 years old, a 2015 Mitsubishi Lancer Evolution has usually seen real wear. Ignition and door cylinders on high-mileage cars wear along with the key, so we cut new keys to factory code rather than copying a worn key. Fob cases crack, buttons wear through and solder joints loosen at this age, so a new shell or a replacement remote often beats repairing the old one. Many have changed hands more than once, so erasing keys you can't account for is worth doing during the visit.

Smart-key cars like the 2015 Lancer Evolution can be targeted with relay attacks that extend the fob's signal from inside your home, so keep fobs away from exterior walls or in a signal-blocking pouch, and have any missing fob erased from the car.

Key options for the 2015 Mitsubishi Lancer Evolution

• 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.
• Smart proximity key (push-to-start). A smart or proximity key lets a 2015 Mitsubishi Lancer Evolution open when you touch the door handle and start with a push of a button while the fob stays in your pocket or bag. Antennas in the doors and cabin send out a low-frequency wake-up signal; the fob answers on a higher radio frequency with an encrypted reply, and the car only allows a start once it confirms the fob is inside. When the fob battery is weak, that conversation fails, which is why most designs include a backup: hold the fob against the start button or set it in a designated pocket. The owner's manual shows where, and it's worth checking before you need it.

How the Mitsubishi immobilizer works on the Lancer Evolution

• The Evolution X shares its key hardware with the Lancer of the same years, so Lancer FCC IDs such as OUC644M-KEY-N and OUCG8D-625M-A are the starting point.
• Evolution X production ended in 2016, and EPA listings show 2015 as its final US model year.

Programming a 2015 Lancer Evolution key

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.

Lost every key to your Lancer Evolution?

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. Entry comes before key-making because we need access to the ignition, the OBD-II port and sometimes the documents in the glove box. We take care with weather stripping, door frames and paint, and we confirm the dash VIN matches your registration before going any further.
3. Originate a new key from the car. Originating a key means building it without a sample. The door lock usually reveals most of the cuts; any it doesn't are worked out by test-cutting and trying the ignition or a second lock. The finished blade should feel like a factory key, not a forced fit.
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. A lost key's metal blade can still open your doors even after its chip is erased. If the keys disappeared along with something showing where you live or park, consider rekeying the car's door lock cylinders too. We'll also recommend leaving with two working keys, not one.

Why a spare key pays for itself

• 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.
• Two drivers sharing one key is a daily negotiation. A second key lets a partner, teenager or coworker use the vehicle without handing keys back and forth in parking lots, and it means one person losing their key ring doesn't leave the whole household stuck.
• 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.

Dealer or mobile locksmith?

Price and parts are the other half of the comparison. Dealers typically sell factory keys only and charge their posted service rates for programming. We offer factory keys where it matters and quality aftermarket alternatives where they perform well, and the quote covers cutting, programming and the trip, with nothing tacked on at the end. Timing differs too. Dealer service departments generally keep business hours, while we take automotive calls every day from 6:30 a.m. to 11:30 p.m., which covers early commutes and late evenings. We're closed overnight, and we'll be upfront if your timing means the dealer or a next-day visit is the better plan. Neither option is wrong; the right one depends on your Lancer Evolution and your schedule.

Lancer Evolution key battery

Battery details for the 2015 Lancer Evolution: CR1620 (remote-head key); CR2032 (FAST-key fob). Swap cells one at a time and match each one exactly; if a key still fails with a fresh battery, the board, buttons or programming may be the problem, which we can test on site.

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. Before cutting or programming, we compare your government photo ID with the vehicle registration or title and check that the VIN on the paperwork matches the VIN on the dash. If the registration is locked inside, we open the car first, confirm the documents, and only then make the key.
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. Cutting happens right beside your car. For a smart key, that means the emergency blade hidden inside the fob; for a transponder or remote-head key, it's the main blade you'll use every day. We deburr the cuts and check the fit in each lock so nothing binds or sticks later on.
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. The last step is a short walkthrough. We show you how many keys the car now recognizes, point out the dead-fob start method for your vehicle, and hand you an itemized receipt. If a spare makes sense, it's simplest to add it during this same visit while the equipment is already connected.

What affects the price of a Lancer Evolution key

• The type of key. Price follows complexity. The more the key does, the more it costs to replace: brass blade, then chip, then remote buttons, then full keyless entry and push-button start. If your Lancer Evolution came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• 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.
• Travel, timing and extra repairs. Sometimes a key problem is really a lock problem: an ignition that won't turn even with the right key, or a door cylinder that has been jammed for years. Fixing those is separate work. We point them out, explain the options, and quote the whole job up front so the bill holds no surprises.

Common Mitsubishi key problems

• 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.
• 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.
• 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.
• 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.

Tips from a mobile locksmith

• 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.
• On any vehicle with a turn-key ignition, keep the key ring light. A heavy cluster of keys, tools and charms swings with every bump and slowly wears the ignition wafers and the key itself. When the key starts to stick or needs a wiggle to turn, deal with it early, before it stops turning entirely.
• 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.

Proof of ownership

Not every situation fits the simple case, so here's how we handle the common exceptions. For a leased or financed vehicle, a registration that lists you as the registered owner or lessee works with your ID. If you just bought the car, bring the signed title or bill of sale along with your ID. For a company or fleet vehicle, we need written authorization from the business plus the driver's ID. If the car belongs to a family member, the registered owner should be present or provide signed permission and a copy of their ID. Rental vehicles go through the rental company.
