2010 Scion xD Key Replacement

2010 xD key specs

The xD came with three-button remote-head keys: lock, unlock and panic in a small head on a TOY43-profile blade, from the same key family as the Yaris and tC. Catalogs list the xD remote both with a 4D-67 chip and in a chipless version marked without anti-theft, and many US-market cars have no immobilizer, so a properly cut plain key can start the engine. A car that does read a transponder, such as a Canadian-market xD, has to have it programmed. Because the blade and electronics share one head, a cracked key usually calls for a new shell rather than a new remote.

What's specific to the 2010 xD

The 2010 Scion xD is the third of 7 model years in the xD XP110 (only generation) (2008–2014), so it shares its key system with the rest of that run, which makes replacement parts easy to source.

A 2010 Scion xD is about 16 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 2010 Scion xD

• 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 2010 Scion xD 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. Before treating a Scion xD key as purely mechanical, we confirm it. Some keys look like plain metal with a rubber or plastic head yet hide a transponder inside, and immobilizers arrived on different trims and model years at different times. If yours truly has no chip, the new key is cut and then tested in the doors, ignition, glove box and trunk where those locks exist. Mechanical blades also show up on newer vehicles as valet keys and as the emergency insert tucked inside a smart fob. Those blades still matter: they're how you get in when a fob battery dies, so they deserve the same careful cutting.

How the Scion immobilizer works on the xD

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.

• Replacement remote-head keys for the 2008-2012 xD are sold under FCC ID MOZB41TG and take a CR2016 battery.
• The same remote-head key family is listed for the Yaris and the 2012-2013 iQ, but chip versions differ, so match the stamp on your blade.
• Shells for the 2014 xD list the newer MOZB52TH remote, so check the FCC ID on your key before ordering.
• If your xD has no immobilizer, re-keying the ignition after a key goes missing is the only way to stop that key from starting it.

Programming a 2010 xD key

On a car without an immobilizer, we cut the blade by duplicating, by code, or by decoding the door lock, then pair the remote buttons. Toyota's on-board add routine, a timed series of door, key and lock-button steps, works on many of these cars, and a programmer handles the rest. If your xD reads a chip, the key is registered through OBD-II instead, with an immobilizer reset when no working key is left.

Lost every key to your xD?

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. 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.
• 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.
• 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.

Dealer or mobile locksmith?

The biggest difference between a dealership and a mobile locksmith is where the work happens. A dealer programs keys in its service bay, so if every key is lost, the car usually has to be towed there, and you work around the service department's schedule and the time it takes to order a key by VIN. Julian's Locksmith brings the cutting machine, key blanks and programming equipment to the car, whether it sits in your driveway, a workplace lot or a parking structure. For a 2010 Scion xD we can program on-site, that means no tow and no shuttle rides back and forth. The trade-off is real, though: on vehicles where only the dealer can program keys, a tow or appointment may still be necessary, and we'll say so before you spend anything on our visit.

xD key battery

Battery details for the 2010 xD: 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 xD 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 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. 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 xD, 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 xD 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.
• 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.
• Inland Empire heat shortens the life of the CR2016 cells used in most Scion remote-head keys. If range drops to a few feet or the buttons work only some of the time, replace the battery before assuming the remote has lost its programming.
• 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.

Tips from a mobile locksmith

• 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.
• 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.
• 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.

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.
