2009 Scion xB Key Replacement

2009 xB key specs

Second-generation xBs came with three-button remote-head keys: lock, unlock and panic in a plastic head molded onto a TOY43-profile blade. A plain metal key without buttons also works the locks and ignition and makes an inexpensive spare. Many US-market cars were built without an immobilizer, and the factory 2013-2015 remote-head key is a no-chip part, so the chip inside some aftermarket keys simply goes unused. A car that does read a transponder, such as a Canadian-market xB, needs it programmed. The 2013 10 Series anniversary edition shipped with jack-knife keys. FCC IDs differ between early and late cars, so we match the one on your key.

What's specific to the 2009 xB

The 2009 Scion xB is the second of 8 model years in the xB E150 (second generation) (2008–2015), so it shares its key system with the rest of that run, which makes replacement parts easy to source.

A 2009 Scion xB is about 17 years old. Original keys are often worn smooth, and some factory remotes for cars this age are discontinued, so we may suggest a quality aftermarket remote or a separate fob. Because older immobilizers are simpler, all-keys-lost jobs on cars this age are usually more straightforward than on late models.

Key options for the 2009 Scion xB

• 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 2009 Scion xB 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.
• Basic mechanical key. With no key left at all, a mechanical-key vehicle is the most straightforward all-keys-lost case there is. Nothing has to be programmed, so the work comes down to reading the lock. We can often get the key code from the VIN through manufacturer channels once ownership is verified. When that isn't available, we decode a door lock with a Lishi-style pick and decoder, which reads each wafer position without removing anything, then cut a key to those depths. Any cuts the door lock doesn't reveal are worked out by progression, test-fitting in the ignition until it turns. For a xB of this type, it is usually the least involved key replacement we do.
• Flip (switchblade) key. A flip key folds its blade into the fob on a spring-loaded hinge and swings it out with the press of a button. Inside the body sit the transponder chip and the remote circuit board, which means the metal blade itself carries no electronics. That's good news when the blade snaps. On many flip keys for a Scion xB, we can cut a new blade to your key code and fit it into your existing fob, with no reprogramming required, because the chip and remote never left the housing. Many flip-key blades are laser-cut, with a groove milled along the side rather than notches on the edge, so they need a code machine built for that profile.

How the Scion immobilizer works on the xB

• Toyota stamps a dot or a G on the blade of a chipped key; an unmarked factory blade on a US xB usually means no transponder.
• Factory remote-head keys for 2008-2012 xBs carry FCC ID HYQ12BBY, while 2013-2015 cars use HYQ12BDP, which Toyota lists as a no-chip part.
• The 2013 xB 10 Series, Scion's tenth-anniversary edition, came with jack-knife keys instead of standard remote heads.
• Toyota's 2014 immobilizer-reset bulletin names the xA, xB, xD, iQ, tC and FR-S, so we test a cut key before assuming any of them has no chip.

Programming a 2009 xB key

On cars without an immobilizer, a new key is cut by code or by decoding a lock, and the remote side of a remote-head key is paired with Toyota's door-and-key add routine or a programmer. If your xB does read a chip, as Canadian-market cars should, we register the transponder through OBD-II, and losing every key means resetting the immobilizer before new keys go in. We test a cut key on your car first, so you know which of these jobs you actually need.

Lost every key to your xB?

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. 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 xB requires, then confirm the engine starts and keeps running and the remote or keyless functions respond.
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

• 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.
• 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.

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 xB and your schedule.

xB key battery

Battery details for the 2009 xB: 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 xB 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 xB 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. 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. 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 xB, 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 xB 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 xB 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. Two cars with similar-looking keys can program very differently. Newer platforms often guard key programming behind encrypted access or paid credentials, while older systems allow straightforward OBD-II pairing. We check the exact procedure for your VIN before quoting, so the number reflects the real work involved.
• 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

• 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.
• 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.
• On a first-generation tC, a spare that was cut but never programmed will turn the ignition and crank the engine, yet the car won't start until the 4D-67 chip is registered. Owners sometimes mistake this for a fuel or starter fault.
• 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.

Tips from a mobile locksmith

• 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.
• 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.
• 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.

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.
