2015 Scion iQ Key Replacement

2015 iQ key specs

Every US iQ uses a conventional ignition and a three-button remote-head key with lock, unlock and panic, from the same Toyota key family as the xD and Yaris. The blade is cut on the TOY43 profile. Many US-market cars were built without an engine immobilizer, so a correctly cut key can start the car, but listings for 2014-2015 cars show a G-chip key that has to be programmed if your car reads it. Replacement remote-head keys come in chipped and chipless versions, and the FCC ID on your key tells us which one fits.

What's specific to the 2015 iQ

2015 was the final model year of the iQ AJ10 (only generation). Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2015 Scion iQ matches a 2012.

At roughly 11 years old, a 2015 Scion iQ 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 2015 Scion iQ

• Remote head key. Remote-head keys look similar across many vehicles, but the electronics inside are not interchangeable. Getting the right one for a Scion iQ means matching the FCC ID and part number printed on the back or inside the case, the operating frequency, which is commonly 315 MHz on US-market cars, the transponder type, and the button layout. A trim with remote start or a power liftgate may use a four- or five-button version where a base trim uses three. We check those details against your VIN and your existing key, if you have one, before cutting the blade. A wrong match can look perfect and still refuse to program.
• Basic mechanical key. Before treating a Scion iQ key as purely mechanical, we confirm it. Some keys look like plain metal with a rubber or plastic head yet hide a transponder inside, and immobilizers arrived on different trims and model years at different times. If yours truly has no chip, the new key is cut and then tested in the doors, ignition, glove box and trunk where those locks exist. Mechanical blades also show up on newer vehicles as valet keys and as the emergency insert tucked inside a smart fob. Those blades still matter: they're how you get in when a fob battery dies, so they deserve the same careful cutting.

How the Scion immobilizer works on the iQ

• Remote-head keys for the iQ are listed under FCC ID MOZB41TG on earlier cars and MOZB52TH, a G-chip part shared with the tC, on 2014-2015 cars.
• An unmarked Toyota blade, with no dot or G stamp, suggests your iQ key has no transponder.
• The iQ was never sold as a Toyota in the US, so parts catalogs list its keys only under Scion.

Programming a 2015 iQ key

For a US iQ without an immobilizer, a spare is a cutting job plus remote pairing: we duplicate or code-cut the blade, decode the door lock if no key is left, and add the remote through Toyota's on-board routine or a programmer. An iQ that reads a chip, including Canadian imports, gets its key registered through OBD-II, with an immobilizer reset if all keys are lost. We test a cut key on your car first so the quote covers only the steps it needs.

Lost every key to your iQ?

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. 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. 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 iQ 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.

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.
• 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?

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 iQ and your schedule.

iQ key battery

Battery details for the 2015 iQ: 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 iQ 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 iQ 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 Scion 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. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Scion 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.
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 an iQ 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 iQ 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. 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 Scion system adds equipment time and labor to the job.

Common Scion key problems

• 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.
• The iA's Mazda smart fob can still start the car with a dead battery: hold the fob against the START/STOP button while pressing the brake. The emergency insert key hidden in the fob opens the driver's door.
• 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.

Tips from a mobile locksmith

• 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.
• 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.
• 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

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.
