2012 Scion xD Key Replacement

2012 xD key specs

The xD came with three-button remote-head keys: lock, unlock and panic in a small head on a TOY43-profile blade, from the same key family as the Yaris and tC. Catalogs list the xD remote both with a 4D-67 chip and in a chipless version marked without anti-theft, and many US-market cars have no immobilizer, so a properly cut plain key can start the engine. A car that does read a transponder, such as a Canadian-market xD, has to have it programmed. Because the blade and electronics share one head, a cracked key usually calls for a new shell rather than a new remote.

What's specific to the 2012 xD

The 2012 Scion xD is the fifth of 7 model years in the xD XP110 (only generation) (2008–2014), so it shares its key system with the rest of that run, which makes replacement parts easy to source.

At roughly 14 years old, a 2012 Scion xD 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.

Key options for the 2012 Scion xD

• 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 2012 xD, we open the old key and show you what's broken before recommending anything.
• Basic mechanical key. A plain mechanical key has no chip and no electronics, just a cut blade that lines up the wafers inside the lock. If your 2012 Scion xD uses one, replacement is mostly a cutting job, but how it's cut matters. Copying a worn key copies its wear, and a duplicate of a duplicate drifts further from spec each time. We prefer to cut by code: we look up or decode the factory bitting, then cut a fresh key to the original depths on a code machine. The result turns smoothly in the doors and ignition instead of needing a jiggle. If the ignition wafers themselves are already worn, we'll point that out too.

How the Scion immobilizer works on the xD

• Replacement remote-head keys for the 2008-2012 xD are sold under FCC ID MOZB41TG and take a CR2016 battery.
• The same remote-head key family is listed for the Yaris and the 2012-2013 iQ, but chip versions differ, so match the stamp on your blade.
• Shells for the 2014 xD list the newer MOZB52TH remote, so check the FCC ID on your key before ordering.
• If your xD has no immobilizer, re-keying the ignition after a key goes missing is the only way to stop that key from starting it.

Programming a 2012 xD key

On a car without an immobilizer, we cut the blade by duplicating, by code, or by decoding the door lock, then pair the remote buttons. Toyota's on-board add routine, a timed series of door, key and lock-button steps, works on many of these cars, and a programmer handles the rest. If your xD reads a chip, the key is registered through OBD-II instead, with an immobilizer reset when no working key is left.

Lost every key to your xD?

Losing every key to a Scion is usually fixable in one visit, but what it takes depends on the model. On cars without an immobilizer, we decode the driver's door lock or cut from the key code, then pair a remote if you want one. On a turn-key tC, the immobilizer is reset through OBD-II before new keys are registered, and we program at least two keys so the lost ones can no longer start the car. Push-button tCs, the FR-S, the iM and the iA take longer: they involve pass-code, PIN or emulator steps, and an occasional car may need the dealer, so we confirm coverage by VIN before we drive out. For the iA, we register new Mazda smart fobs and cut the emergency blade to match the door lock. In every case, expect us to verify your ID and proof of ownership 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. 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 Scion xD 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

• 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.
• 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.
• 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?

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

xD key battery

Battery details for the 2012 xD: CR2016 (remote-head 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 xD 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 Scion xD 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. 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 xD, 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 xD 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 Scion xD 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.
• 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. Because we come to you, the distance from our San Bernardino base and the time of the call play a part. So does anything we find along the way, such as a worn ignition cylinder or a seized door lock. You hear about each item and get a quote before we start work.

Call (951) 903-3193 with your VIN and the keys you still have, and we'll quote the job before any work starts.

Common Scion key problems

• On a first-generation tC, a spare that was cut but never programmed will turn the ignition and crank the engine, yet the car won't start until the 4D-67 chip is registered. Owners sometimes mistake this for a fuel or starter fault.
• Scion remote-head keys often crack where the blade meets the plastic head. The circuit board usually survives, so a new shell with a freshly cut blade can fix it, provided the transponder chip moves across with the board.
• Inland Empire heat shortens the life of the CR2016 cells used in most Scion remote-head keys. If range drops to a few feet or the buttons work only some of the time, replace the battery before assuming the remote has lost its programming.
• Toyota marks chipped blades with a stamped dot (4D-67), G or H near the head. Replacement remote-head keys for the tC, xB, xD and iQ come in chipped and chipless versions that look alike, so match the stamp and FCC ID before buying one online.

Tips from a mobile locksmith

• Southern California heat is hard on keys. Fob batteries drain faster, plastic housings turn brittle, and rubber button pads crack when a key spends summer afternoons on a dashboard or in a sunny cup holder. Carry the fob with you or keep it shaded, and replace batteries before summer rather than after they fail.
• 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.
• Every so often, use the mechanical blade in the driver's door lock. Cylinders that go years without a key can seize from dust and dried grease, and you won't find out until the day the fob dies and the blade is your only way in. A small shot of dry lubricant keeps the lock ready.

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.
