2024 Mitsubishi Mirage Key Replacement

2024 Mirage key specs

From 2017, base hatchbacks use a three-button remote-head key, FCC ID OUCJ166N, the same key listed for the Mirage G4 sedan. Upper trims such as the SE got FAST-key with push-button start. From 2019 the smart key is the OUCGHR-M013 fob also used on the Eclipse Cross, and 2017-2018 cars may carry the earlier OUC003M fob, so we confirm by build date. Each smart key holds an emergency blade cut to the driver's door lock. The remote-head key takes a CR1620 and the smart key a CR2032.

What's specific to the 2024 Mirage

2024 was the final model year of the Mirage Sixth generation facelift. Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2024 Mitsubishi Mirage matches a 2017. At 2 years old, a 2024 Mitsubishi Mirage is usually still on its original keys and fob batteries. The most common call for a car this new is a second key, since many buyers leave the dealer with only one, or a replacement after a lost fob.

Smart-key cars like the 2024 Mirage 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 2024 Mitsubishi Mirage

• Remote head key. A remote-head key puts two separate systems in one piece: a cut blade with a transponder chip that the immobilizer reads, and a small circuit board with buttons that signals the body control module to work the door locks. On a 2024 Mitsubishi Mirage with this style of key, each side is programmed separately. That explains some confusing failures. If the remote stops working but the car still starts, the problem is usually the battery or the remote board. If the buttons work but the engine won't run, look at the chip side. Knowing which half failed tells us whether you need a repair, a reprogram or a whole new key.
• 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 Mirage Sixth generation facelift, 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.

How the Mitsubishi immobilizer works on the Mirage

• Supplier listings show the same OUCJ166N remote-head key fitting the Mirage hatchback and Mirage G4 sedan from 2017 through 2024.
• EPA listings end with the 2024 model year, and Mitsubishi stopped building the Mirage later that year.

Programming a 2024 Mirage key

Remote-head keys are added over the OBD-II port with a programmer and the PIN, and all-keys-lost on a turn-key Mirage is usually an on-site job. Smart keys go through the same port, but the PIN often has to come from the dealer or from a tool that calculates it. The fob must be new or unlocked, and its emergency blade is cut to your door lock.

Turn-key Mirages are usually straightforward, including all-keys-lost. FAST-key cars with no working fob may need a dealer PIN first.

Lost every key to your Mirage?

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. Find your registration or title and a government photo ID in the same name. Note the VIN, which is printed on the driver's side of the dashboard and usually on your insurance card. If the paperwork is locked in the car, tell us; we'll open the vehicle first and check it there.
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 Mirage 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

• 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.
• 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.
• When you sell or trade in the vehicle, buyers and dealers expect two keys. A missing key can come up during an appraisal or a private-sale negotiation, so having both on hand keeps the conversation about the car, not about what it will cost the next owner to replace one.

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 Mirage, ask us directly and you'll get a plain answer.

Mirage key battery

Battery details for the 2024 Mirage: CR1620 (remote-head key); CR2032 (smart key). 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 Mirage 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 Mirage 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. If you still have a working key, we can read its cuts directly and check them against the factory depths for the Mitsubishi keyway. A worn key gets corrected back to spec during this step, so the new key turns crisply instead of reproducing years of wear in a fresh piece of metal.
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 Mirage, 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 Mirage 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 Mirage came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• 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.
• Programming complexity and security access. Two cars with similar-looking keys can program very differently. Newer platforms often guard key programming behind encrypted access or paid credentials, while older systems allow straightforward OBD-II pairing. We check the exact procedure for your VIN before quoting, so the number reflects the real work involved.

Common Mitsubishi key problems

• 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.
• 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.
• 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.

Tips from a mobile locksmith

• Learn your car's dead-fob start method now, in the driveway, rather than in a dark parking lot later. Depending on the make, you hold the fob against the start button or place it in a marked pocket in the console. Also find the hidden keyhole on the driver's door handle and practice using the emergency blade.
• When a key's head cracks or its blade bends, replace it before it fails. A transponder chip can slip out of a split head, and a bent blade can break off inside the ignition or door lock, turning a simple key replacement into an extraction and repair job. Small symptoms are the inexpensive time to act.
• 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.

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.
