2018 Mitsubishi Outlander PHEV Key Replacement
Short answer: The 2018 Mitsubishi Outlander PHEV belongs to the Outlander PHEV GG (third-generation based) and uses a smart proximity key with push-button start. We can usually add spare keys on site; some situations, such as all keys lost on certain trims, need extra steps or a dealer-supplied part. Julian's Locksmith cuts and programs Outlander PHEV keys on site; call (951) 903-3193 with your VIN for a quote.

Bought a used 2018 Mitsubishi Outlander PHEV and got one key at signing? That's common, and it's worth fixing early. A single key leaves you one lost pocket away from an all-keys-lost job, and you have no idea how many other keys the previous owners had programmed to the car. Julian's Locksmith can meet you in Southern California, verify the registration in your name, cut and program a second key, and, where the system allows, clear old keys from the immobilizer so only the ones in your hand will start the engine. It's a simple step that protects both the car and your budget, and we walk you through exactly what was done before we pack up.

Every 2018-2022 Outlander PHEV uses a FAST-key smart fob and a push-button power switch. The fob is the familiar OUC644M-KEY-N design, but PHEV versions add a button tied to the charging timer: the four-button fob has lock, unlock, panic and that charge button, and the five-button fob adds a power liftgate button. Each fob holds an emergency blade for the driver's door and runs on a CR2032. Supplier listings for these fobs stop at 2020, so we confirm 2021 and 2022 trucks by VIN.
What's specific to the 2018 Outlander PHEV
2018 was the first model year of the Outlander PHEV GG (third-generation based). Early-production cars sometimes use different part numbers than later ones, so for a 2018 Mitsubishi Outlander PHEV we confirm the exact key from the VIN or the old key's FCC ID before cutting anything. At roughly 8 years old, a 2018 Mitsubishi Outlander PHEV has usually seen real wear. 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 2018 Outlander PHEV 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 2018 Mitsubishi Outlander PHEV
- 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 Outlander PHEV GG (third-generation based), 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 Outlander PHEV
- The five-button PHEV fob is Mitsubishi part 8637B666, and the four-button version without a liftgate button is 8637B665.
- EPA listings show this PHEV running from the 2018 through 2022 model years before the redesign.
- With no ignition cylinder, the emergency blade in the fob is there to open the driver's door.
Programming a 2018 Outlander PHEV key
PHEV fobs are registered through the OBD-II port with a programmer and the vehicle PIN, using the same keyless operation routine as the gasoline Outlander of these years. The fob must be new or unlocked, and the PHEV part number matters because the gas truck's fob lacks the charge button. Adding a spare is routine. All-keys-lost is usually handled on site, though we confirm tool coverage for your exact year first.
Spare fobs are routine. We confirm all-keys-lost coverage for your PHEV's year by VIN before quoting, since a few cases may need a dealer step.
Lost every key to your Outlander PHEV?
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.
- 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.
- 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.
- 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.
- 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 Outlander PHEV requires, then confirm the engine starts and keeps running and the remote or keyless functions respond.
- 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.
- A spare stored safely at home rescues you from a locked car with the fob sitting on the seat, a key dropped somewhere along a hiking trail, or a fob that stops responding on a busy morning. Keep it indoors, never in a magnetic box under the bumper.
Dealer or mobile locksmith?
The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a 2018 Mitsubishi Outlander PHEV we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.
Outlander PHEV key battery
Most fobs for a 2018 Mitsubishi Outlander PHEV open along a small slot in the seam; a coin or a plastic pry tool works better than a screwdriver, which chews up the housing. If the fob hides a mechanical blade, slide it out first, since the case often opens from that gap. Note which side of the old cell faces up, swap in a fresh CR2032, and press the halves together until they click all the way around. Handle the new battery by its edges, because skin oil on the faces can hurt contact. In most cases the fob keeps its programming through a battery change, so test lock, unlock and start, and you're done.
How the job works
- Identify the exact key your Outlander PHEV uses. We ask a few quick questions on the phone: the year, whether the car starts with a turn key or a button, how many keys you have left, and whether the remote still works the doors. Then we check the VIN against our programming references so the van arrives with the correct blank or fob, not a close guess.
- 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.
- 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.
- 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.
- Program the chip, remote or smart key. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Mitsubishi system, this may involve a security PIN, a timed waiting period, or on-board button sequences for the remote. On some vehicles we clone a working key's chip instead, when that's the more reliable path.
- 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 an Outlander PHEV 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 Outlander PHEV is the most involved of all, both in the part itself and in the programming.
- All keys lost or adding a key. On some vehicles, losing the last key changes the programming entirely, from a quick add-key procedure to a full immobilizer reset or a module read on the bench. That extra labor shows up in the price, and it's the strongest argument for keeping a spare in the house.
- Programming complexity and security access. Some immobilizers accept a new key with a few on-board steps. Others need a PIN code, a timed security wait, manufacturer online access, or removing a module to read its data. Every extra layer of security on the Mitsubishi system adds equipment time and labor to the job.
- 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
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
Proof of ownership
Making car keys is regulated work in California. Locksmiths are licensed and overseen by the Bureau of Security and Investigative Services under the Locksmith Act, Business and Professions Code section 6980 and following, and Julian's Locksmith holds company license LCO7891. Verification protects you more than anyone: a locksmith who will make a key for whoever asks will also make one for someone who wants your car. We record your name, the vehicle and its VIN on a work order, and we politely decline jobs where ownership can't be established. You can look up our license at search.dca.ca.gov.

Frequently asked questions
Can a locksmith make a key for a 2018 Mitsubishi Outlander PHEV?
We can usually add spare keys on site; some situations, such as all keys lost on certain trims, need extra steps or a dealer-supplied part. Spare fobs are routine. We confirm all-keys-lost coverage for your PHEV's year by VIN before quoting, since a few cases may need a dealer step. The 2018 Outlander PHEV uses a smart proximity key with push-button start.
What happens to the key I lost? Can it still start my Mitsubishi?
When we program new keys, we can usually erase lost keys from the immobilizer, which stops them from starting the engine. On some systems the car only remembers the keys present during programming, so the lost one drops off automatically. Keep in mind that a lost key's metal blade can still open the doors, so if it went missing with something that shows your address, ask about rekeying the door locks.
Is an aftermarket key as good as a factory key for a Mitsubishi Outlander PHEV?
For many vehicles, a quality aftermarket key works just like the original: it starts the car, operates the locks and fits the keyways. Differences tend to show up in housing durability, button feel and sometimes remote range. For certain smart keys, a factory fob is the more reliable choice. We'll tell you honestly which options we'd put on our own car for your Outlander PHEV and let you make the call.
When can you come out to Southern California for a car key?
We work every day from 6:30 a.m. to 11:30 p.m., weekends included. Weekends are included. Call (951) 903-3193 and we'll give you an honest ETA to Southern California based on where we are at the time. If you're stuck outside our hours, it's usually smarter to leave the car parked and locked, get home safely, and call when we open than to pay for an overnight tow.
Can you fix a broken Mitsubishi key instead of replacing it?
Often, yes. If the shell is cracked, the buttons are worn or the blade snapped, but the circuit board and chip are healthy, we can transfer the electronics into a new housing and cut a fresh blade to your key code. Your existing programming stays intact. If the board has been damaged by water or impact, a repair won't last, and we'll recommend a new programmed key instead.
What do I need to show before you make a key for my Outlander PHEV?
A current registration or title and a government-issued photo ID in the same name. We match the VIN on the paperwork with the one on the dashboard before any cutting or programming. If you're not the registered owner, bring the owner's written authorization and a copy of their ID. If the documents are locked in the car, we'll open it first and check them there.
Is the 2018 Mitsubishi Outlander PHEV push-to-start?
Yes. The 2018 Outlander PHEV uses push-button start with a smart proximity key, so a replacement has to be a programmed smart fob, not just a cut blade. The fob also hides a mechanical emergency blade for the doors.
What battery does a 2018 Mitsubishi Outlander PHEV key use?
Fobs for the 2018 Outlander PHEV use a CR2032 coin cell. Replace it when range drops or the car shows a key-battery warning. If the fob still fails with a fresh battery, the board, buttons or programming may be the problem, which we can test on site.
