2016 Scion FR-S Key Replacement

2016 FR-S key specs

Most FR-S coupes start with a turn-key ignition. The factory key is a four-button remote-head key, with lock, unlock, panic and trunk buttons, on a blade with Toyota's TR47 keyway. Inside is a Toyota G transponder rather than a Subaru chip. Replacement keys for 2013-2015 cars are sold under FCC ID HYQ12BBY, and 2016 cars under HYQ12BEL. Limited editions, including the 2013 10 Series and the 2014 Release Series 1.0, have push-button start and a four-button smart fob listed under FCC ID HYQ14ACX, so we check which system your car has.

What's specific to the 2016 FR-S

2016 was the final model year of the FR-S ZN6 (first generation). Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2016 Scion FR-S matches a 2013. At roughly 10 years old, a 2016 Scion FR-S 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.

Smart-key cars like the 2016 FR-S 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 2016 Scion FR-S

• 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 2016 Scion FR-S 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). A smart or proximity key lets a 2016 Scion FR-S open when you touch the door handle and start with a push of a button while the fob stays in your pocket or bag. Antennas in the doors and cabin send out a low-frequency wake-up signal; the fob answers on a higher radio frequency with an encrypted reply, and the car only allows a start once it confirms the fob is inside. When the fob battery is weak, that conversation fails, which is why most designs include a backup: hold the fob against the start button or set it in a designated pocket. The owner's manual shows where, and it's worth checking before you need it.
• Transponder (chip) key. A transponder key carries a small chip in its head, usually a glass capsule or a carbon wafer, with no battery of its own. When you turn the key in a 2016 Scion FR-S that uses one, an antenna ring around the ignition energizes the chip and asks for its code. If the answer matches what the immobilizer has stored, the engine is allowed to run. If it doesn't, you get the classic symptoms: the engine cranks but won't fire, or it fires and dies after a second, and the security light on the dash flashes or stays lit. That's why a perfectly cut copy without a programmed chip will open the doors but won't start the car.

How the Scion immobilizer works on the FR-S

Scion was Toyota's youth brand from the 2004 through 2016 model years, so most Scion key systems are Toyota systems underneath, and the last few came from partners. What surprises owners is how uneven the immobilizer picture is. The tC is the Scion where a transponder immobilizer is the norm: a Texas 4D-67 chip through 2010, then Toyota's 80-bit G chip from about 2011. The low-priced boxes and hatchbacks are different. Parts catalogs list their remote keys in versions with and without anti-theft, and installer reports say many US xAs, xBs, xDs and iQs have no immobilizer at all, so a plain cut key starts them. Canadian-market versions should read a chip, because Canada has required immobilizers on new cars since 2007. The final three Scions broke the pattern. The Subaru-built FR-S uses a Toyota G chip in a four-button remote-head key, with a smart fob on its push-button editions. The iA is a Mazda2 sedan with Mazda's push-button smart key and NXP Hitag Pro fob, and the iM, a European Auris, uses a 128-bit Toyota H (8A) flip key. Because the same badge hides such different systems, we start every Scion job by checking your key and the car itself.

• FR-S remote-head keys carry a Toyota G chip even though Subaru built the car.
• The 2016 remote-head key, FCC ID HYQ12BEL, is also listed for the 2017 Toyota 86, the FR-S renamed after Scion closed.
• Toyota's 2014 service bulletin on immobilizer and smart key resets names the FR-S and requires a dealer-issued pass-code, which is why all-keys-lost takes longer.

Programming a 2016 FR-S key

The chip in an FR-S key is registered through the OBD-II port with equipment that supports this Subaru-built Toyota platform, and the remote buttons are added during the same visit. Adding a spare with a working key is routine. All-keys-lost needs a security pass-code exchange, as Toyota's own reset procedure does; aftermarket tools can handle many of these cars, but it takes longer and an occasional car may need the dealer. Push-button editions add smart key steps. The blade is cut by code or decoded from the door lock.

Spare keys are routine. All-keys-lost takes a pass-code-protected procedure, and push-button editions add smart key steps, so we confirm by VIN that our equipment covers your car before the visit.

Lost every key to your FR-S?

1. Gather your documents and the VIN. Call with the year, make, model and VIN if you can read it through the windshield, plus where the car is parked. Those details let us confirm whether your Scion FR-S can be done on-site and bring the right key, so the first trip is the only trip.
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 FR-S 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 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.
• 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.
• 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.

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 FR-S and your schedule.

FR-S key battery

Battery details for the 2016 FR-S: 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 FR-S 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 FR-S 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. 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. Before we leave, every function gets checked: doors, trunk or liftgate, panic button, remote range, engine start, and the emergency blade in the driver's door. If keys are missing, we delete them from the car's memory where the system allows, so a lost key can no longer start the engine.

What affects the price of an FR-S 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 FR-S came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• 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.
• 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. 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 Scion key problems

• Installer reports say many US-market second-generation xBs, xDs and iQs have no engine immobilizer, so any correctly cut key can start the car. That makes a lost key a real theft risk, and re-keying the ignition and door locks is worth considering.
• The separate remote on the first-generation xB is a common Toyota design shared with early-2000s Highlander, RAV4 and Tacoma models, so replacements are easy to find and can usually be paired on board without a computer.
• 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

• Be careful with discount fobs from online marketplaces. A listing may match your remote's shape while using a different frequency, chip or FCC ID, and many used smart keys are locked to their original vehicle. If you already bought one, send us the listing or a photo before the visit so nobody pays for a programming attempt that can't work.
• 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.
• 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.

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.
