2022 Subaru BRZ Key Replacement

2022 BRZ key specs

Every second-generation BRZ starts with a button. Each car uses a Subaru smart fob with a slide-out emergency blade for the driver's door, and there is no remote-head key in this generation. Premium and Limited models were sold at launch, and the tS joined later as a more track-focused trim. Subaru's 2026 press kit lists the Limited, tS and Series.Yellow, with the Premium discontinued.

What's specific to the 2022 BRZ

2022 was the first model year of the BRZ ZD8 (second generation). Early-production cars sometimes use different part numbers than later ones, so for a 2022 Subaru BRZ we confirm the exact key from the VIN or the old key's FCC ID before cutting anything. It also marks a change from the previous generation: the 2020 BRZ used a remote head key and a smart proximity key with push-button start, while the 2022 uses a smart proximity key with push-button start. Keys from the older car will not work in this one.

A 2022 Subaru BRZ is about 4 years old now. Original fob batteries are near the end of their life at this age, so weak range or a "key not detected" message is often a battery before it is a failed fob. Cars this age are often on their second owner, which is when a single remaining key and a request for a spare tend to show up.

Key options for the 2022 Subaru BRZ

• Smart proximity key (push-to-start). Proximity keys bring a security trade-off worth understanding. Because the fob is always listening, thieves with relay equipment can stretch its signal from inside your house to the car in the driveway. Keeping the fob away from exterior walls, or in a signal-blocking pouch, closes that gap, and some fobs offer a sleep mode described in the owner's manual. If a smart key for your 2022 Subaru BRZ is lost or stolen, programming a replacement is the moment to delete the missing fob from the car's memory. And be wary of used fobs from online sellers: a lot of them are locked to the vehicle they came from and can't be reprogrammed to yours.

How the Subaru immobilizer works on the BRZ

Subaru came to engine immobilizers later than most brands sold in the US, which keeps things simple for owners of early-2000s models: no 2000-2004 US Subaru has a transponder, so a correctly cut key starts the car. Subaru's own chart shows immobilizers arriving by model and trim from the 2005 model year. That year only the Forester XT, Impreza STi, Legacy GT and Outback XT and 3.0R had one. Every Legacy, Outback and Tribeca followed for 2006, the WRX joined the STi, the whole Impreza line had one by 2008 and the whole Forester line by 2009. The first systems use Texas 4D62 chips in side-cut keys. Subaru then moved to high-security laser-cut keys on 2008-2011 Imprezas, 2008-2014 WRX and STI models, 2009-2013 Foresters and 2010-2014 Legacy and Outback models. From the 2012 Impreza, an 80-bit Subaru G chip arrived in a side-cut remote-head key. The 2017 Impreza introduced the 128-bit Subaru H chip, which reached the Crosstrek for 2018, the Forester and Ascent for 2019 and the Legacy and Outback for 2020. Keyless Access smart keys began with the 2013 BRZ and the 2013-2014 Legacy and Outback.

• Supplier listings pair FCC ID HYQ14AHK and a CR2032 battery with the 2022-2023 Toyota GR86, the BRZ's twin.
• Subaru did not sell a 2021 BRZ in the US; this generation started with the 2022 model year.
• Subaru's 2026 BRZ press kit lists the Limited, tS and Series.Yellow, and the Limited has push-button start.

Programming a 2022 BRZ key

Adding a fob with a working one present is done through the OBD-II port with current software. All-keys-lost is possible with specialized tools, such as a dedicated Subaru license that lists 2021-and-later BRZ and GR86 smart-key cars, but not every programmer handles it, and some cases still end at the dealer. The smart fob must be new or reset to blank before it will register to your car.

Spare fobs are routine. All-keys-lost needs specialized Subaru software, and some cars may need the dealer.

Lost every key to your BRZ?

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. 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.
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. 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

• 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 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.
• 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?

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 BRZ and your schedule.

BRZ key battery

If a new CR2032 doesn't bring the fob back, the battery wasn't the problem. Common culprits include a battery holder whose solder joints have cracked from drops, contacts corroded by moisture, worn rubber button pads that no longer reach the circuit, or a board damaged by water. We can test whether the fob is transmitting at all and inspect the board closely. Sometimes a new shell or a resoldered holder solves it; sometimes the fob has to be replaced and programmed. Meanwhile, the car can usually still be started with the fob held at the backup spot described in the owner's manual.

How the job works

1. Identify the exact key your BRZ 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.
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 Subaru 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. 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 BRZ, you'll have heard that before we arrived, not halfway through the job.
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 a BRZ key

• Factory or aftermarket parts. Factory keys and fobs carry the manufacturer's part number and usually the highest parts cost. Quality aftermarket keys use compatible electronics at a lower price and work well on many vehicles. We tell you which options we trust for your car, and where an aftermarket version has known range or fit issues, we steer you to OEM.
• 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.
• Blade style and cutting. Traditional edge-cut blades are quick to cut. High-security laser-cut blades, with a groove milled into the side, need a specialized machine and more care, and the blanks themselves cost more. If we have to decode a lock to find the cuts, that adds labor as well.
• 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.

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

Common Subaru key problems

• Remote-head key shells tend to crack at the blade root after years on a heavy keyring. The remote board and transponder can usually be moved into a new shell with a freshly cut blade, which often costs less than a complete new key.
• Used Subaru fobs sold online can arrive already programmed to another car. Ask whether a fob is new or reset to a blank state before you buy, and bring the part number and FCC ID from your old key so we can confirm the fit before programming.
• Subaru remotes of one era were built on two frequencies under different FCC IDs: CWTWB1U811 at 315 MHz and CWTWBU766 at 433.92 MHz. Both appear on remote-head keys for 2010-2015 Subarus, so match the part number printed on your old key before you buy a replacement.

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.
• 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.
• 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.

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.
