2017 Subaru Crosstrek Key Replacement

2017 Crosstrek key specs

Most first-generation Crosstreks use a four-button remote-head key with a side-cut blade and the 80-bit G chip, the same key as the 2012-2016 Impreza. Keyless Access with push-button start appeared on the 2014 Crosstrek Hybrid and on upper trims from 2015, using a smart fob with an emergency blade. The model dropped the XV prefix for 2016, but the keys didn't change with the name.

What's specific to the 2017 Crosstrek

2017 was the final model year of the Crosstrek GP (first generation, XV Crosstrek), before the GT (second generation) arrived for 2018. Late-run cars occasionally pick up running changes, so we check the VIN instead of assuming a 2017 Subaru Crosstrek matches a 2013.

At roughly 9 years old, a 2017 Subaru Crosstrek 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 2017 Subaru Crosstrek

• 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 2017 Crosstrek, we open the old key and show you what's broken before recommending anything.
• Smart proximity key (push-to-start). Making a new smart key is mostly a programming job. The fob has to match the vehicle's FCC ID, frequency and chip, and then the keyless system must be told to accept it, normally through the OBD-II port. Depending on the platform, that can mean entering a PIN, waiting through a timed security procedure, or on some newer vehicles, using manufacturer online access. When every key is lost, certain models need a module removed and read on the bench. For your Subaru Crosstrek GP (first generation, XV Crosstrek), we'll tell you which of those applies, and if a step is dealer-only, you'll hear it before we drive out. The emergency blade hidden inside the fob is cut by code during the same visit.

How the Subaru immobilizer works on the Crosstrek

• Subaru's key bulletin shows the 2013 XV Crosstrek sharing the Impreza's side-cut remote-head key.
• The bulletin lists Keyless Access on the 2014 Crosstrek Hybrid with a 5+4 emergency key, and a thinner 4+4 emergency key from 2015.

Programming a 2017 Crosstrek key

Remote-head keys and smart fobs program through the OBD-II port, and the remote is learned in the same session when a working key is present. Smart fobs must be new or reset to blank. With every key lost, remote-head cars follow Subaru's immobilizer procedure and are usually fine, while smart-key cars can need special tools or the dealer. The blade or emergency insert is cut from your key code or by decoding the driver's door lock.

A Subaru built before its line got an immobilizer only needs a correctly cut key. We cut from the key code, which Subaru releases by VIN through its lock information service (a paid site for professional locksmiths), or by decoding a lock. Transponder Subarus from 2005 through the G-chip years are programmed through the OBD-II port, and Subaru's own procedure relies on an immobilizer security ID that is released along with the key code. Remote-head keys are normally registered as transmitters in the same session on 2012 and later cars, while the separate fobs of earlier years have their own routines. H-chip cars accept an added key readily when a working key is present, but all-keys-lost needs dedicated Subaru software, an emulator or bench work, and Keyless Access fobs must be new or reset to blank. Bring every key you still have, and expect us to check ID and registration first.

Spare keys are routine. All-keys-lost on remote-head cars is usually fine, but Keyless Access cars can need special tools or the dealer.

Lost every key to your Crosstrek?

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 Subaru Crosstrek 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. 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. 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

• 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.
• 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 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?

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 Subaru Crosstrek, ask us directly and you'll get a plain answer.

Crosstrek key battery

Battery details for the 2017 Crosstrek: CR1620 (remote-head key); CR2032 (smart fob). 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 Crosstrek 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. 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. 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 Crosstrek, 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 Crosstrek 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 Crosstrek came with different key styles by trim, the one your car actually uses is the one that sets the quote.
• 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.
• 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 Subaru 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.

Tips from a mobile locksmith

• Make the spare before you need it. Adding a key while one still works is quicker and less expensive than starting from nothing, and it keeps the simpler programming options available. Good moments are right after buying the car, or as soon as one of your two keys goes missing.
• If your vehicle has a proximity key, think about where it sleeps at night. A fob hanging by the front door can sit within range of relay equipment used to open and start cars from outside. A drawer deeper inside the house, a signal-blocking pouch, or the fob's own sleep mode reduces that risk considerably.
• 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.
• 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.
• 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

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.
