2015 Toyota Yaris Key Replacement

2015 Yaris key specs

The redesigned Toyota-built Yaris hatchback keeps a turn-key ignition. Its keys use Toyota's 80-bit G chip, identified by a G on the blade, and the remote-head version has three buttons and a CR2016 (FCC HYQ12BBY). Plain transponder keys without buttons are available as spares. Supplier notes say to check the chip on 2015 cars, since Toyota's 128-bit H chip was arriving about then, and the H-chip hatchbacks are covered in the next entry.

What's specific to the 2015 Yaris

2015 was the final model year of the Yaris XP130 hatchback (G-chip years), before the XP130 hatchback (H-chip years) and Yaris iA sedan arrived for 2016. Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2015 Toyota Yaris matches a 2012.

At roughly 11 years old, a 2015 Toyota Yaris 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 Toyota Yaris

• Transponder (chip) key. There are two ways to give a new transponder key the right identity. Cloning reads the chip in a working key and writes that same ID onto a special cloneable chip, so the car can't tell the two apart. Programming adds a brand-new key ID to the immobilizer's memory through the OBD-II port, sometimes after entering a security PIN tied to the VIN. Cloning is handy when you have a working key and the chip family supports it. Programming is the better choice when keys are lost, because it also lets us remove keys you no longer control from the car's memory. For your Toyota Yaris, we'll explain which method fits and why.
• Remote head key. Remote-head keys look similar across many vehicles, but the electronics inside are not interchangeable. Getting the right one for a Toyota Yaris 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.

How the Toyota immobilizer works on the Yaris

• The G-chip remote-head key, Toyota part 89070-33C40 with FCC ID HYQ12BBY, is listed for 2010-2014 Yaris cars.
• The blade letter decides the key: G for the 80-bit chip and H for the 128-bit chip, and neither will program in place of the other.

Programming a 2015 Yaris key

G-chip keys are registered over OBD-II, and with a working master many cars also allow Toyota's on-board add. All-keys-lost on a G-chip Yaris is an immobilizer reset with a built-in security wait, after which every key you keep is registered fresh. The remote-head key's buttons pair as a separate step, and we read your existing key or check the blade letter first so we program the right chip type.

Lost every key to your Yaris?

Losing every Toyota key is solvable in most cases, but the method depends on the system. On 4D-67 and G-chip cars, our equipment resets the immobilizer through OBD-II, usually after a built-in security wait, and then registers new keys. H-chip and 8A smart key cars usually need an emulator or a direct connection at the immobilizer or smart key box, which can mean removing a panel under the dash. Older 4C cars and early smart key systems may need the module's memory read on the bench. Toyota's newest BA and Hitag AES systems have aftermarket all-keys-lost coverage on many models but not all, and the BMW-built GR Supra is a dealer job. We confirm your VIN before driving out, verify ID and ownership on site, and program at least two keys.

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. Next, the new key is introduced to the car's security system. Many vehicles allow this through the OBD-II port with a PIN or security procedure. Some all-keys-lost cases require reading a module on the bench, and a few platforms only allow dealer programming, which we'll tell you up front.
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.
• 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.
• 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 Yaris and your schedule.

Yaris key battery

Battery details for the 2015 Yaris: 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 Yaris 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 Toyota Yaris 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. With the blade done, we connect to the OBD-II port and register the new key with the immobilizer. Depending on the Toyota 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 a Yaris 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 Yaris 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.
• 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 Toyota 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 Toyota key problems

• Toyota chip keys are easy to mix up. Many later keys are stamped near the head with D for the 4D-67 chip, G for the 80-bit G chip or H for the 128-bit H chip, and a key ordered by looks alone often won't program.
• If a smart key battery dies, most push-button Toyotas will still start. Press the brake and touch the Toyota emblem side of the fob to the start button; the car reads the chip directly, so a flat cell isn't a lockout.
• Older Toyotas came with black master keys and gray valet keys. The valet key starts the car but can't be used for Toyota's on-board method of adding keys, so a car with only valet keys left needs programming equipment.
• Many newer Toyota fobs have a battery-saving mode, switched on by holding lock and pressing unlock twice. Afterward the car ignores the fob in your pocket until a button is pressed, which owners often mistake for a dead key.

Tips from a mobile locksmith

• 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.
• 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.
• 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

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.
