2016 Kia K900 Key Replacement

2016 K900 key specs

Every first-generation K900 starts with a four-button smart key (lock, unlock, trunk, panic) and a START button. Supplier listings show FCC ID SY5KHFNA433 at 433 MHz under parts 95440-3T200 and 95440-3T300, powered by a CR2032, with an emergency key on the LXP90 track profile shared with the 2014-2016 Cadenza. The listings note the fob can be reused after it is unlocked, which helps when new ones are scarce. If only the case is cracked, a new shell may be the cheaper fix.

What's specific to the 2016 K900

The 2016 Kia K900 is the second of 4 model years in the K900 KH (first generation) (2015–2018), so it shares its key system with the rest of that run, which makes replacement parts easy to source.

At roughly 10 years old, a 2016 Kia K900 has usually seen real wear. 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 2016 Kia K900

• 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 Kia K900 KH (first generation), 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 Kia immobilizer works on the K900

Kia keys sold in the US fall into three rough groups, and which group your car belongs to matters more than its age. The first is the upscale models that always had a transponder. The 2004-2006 Amanti used a Texas 4D60 chip, the 2007-2009 Amanti a Philips ID46, and the Borrego, Cadenza and K900 carried chipped keys or smart keys from the start. The second group is the large number of turn-key Kias, from many economy cars of the 2000s through the 2011 to 2021 model years, that have no engine immobilizer at all, including base versions of the Forte, Optima, Rio, Sedona, Sorento, Soul and Sportage. A correctly cut blade starts those cars, which made them theft targets and is why Kia now offers a free anti-theft software upgrade. The third group is push-button cars, where the car has to recognize the smart key before it will start. Those fobs moved from 315 MHz to 433 MHz in the mid-2010s and later to Hitag AES encryption, and several of the newest fobs take a thicker CR2450 battery. Current EV6 and EV9 models also offer Kia Digital Key 2.0 on a phone.

• Supplier catalogs list the same LXP90-profile emergency key for the first-generation K900 and the 2014-2016 Cadenza.
• Supplier listings describe the SY5KHFNA433 fob as reusable once unlocked, which widens the pool of usable parts.
• Supplier listings carry the newer TQ8-FOB-4F17 fob from 2018, so check the FCC ID on a 2018 car before ordering.

Programming a 2016 K900 key

New fobs are registered through the OBD-II port with the immobilizer PIN, and a fob must be new or professionally unlocked before your car will learn it. Registration rewrites the key list, so bring every fob. All-keys-lost uses the same process once we're inside, with the emergency blade cut by code or by decoding the lock. The practical hurdle is parts, so we confirm a fob is available for your VIN before scheduling.

Programming is well covered, but fobs for this low-volume sedan can be scarce, so we confirm parts and coverage by VIN before booking.

Lost every key to your K900?

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 Kia K900 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 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.
• 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 2016 Kia K900 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.

K900 key battery

Most fobs for a 2016 Kia K900 open along a small slot in the seam; a coin or a plastic pry tool works better than a screwdriver, which chews up the housing. If the fob hides a mechanical blade, slide it out first, since the case often opens from that gap. Note which side of the old cell faces up, swap in a fresh CR2032, and press the halves together until they click all the way around. Handle the new battery by its edges, because skin oil on the faces can hurt contact. In most cases the fob keeps its programming through a battery change, so test lock, unlock and start, and you're done.

How the job works

1. Identify the exact key your K900 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. 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 K900, you'll have heard that before we arrived, not halfway through the job.
6. Test everything and clear out old keys. The last step is a short walkthrough. We show you how many keys the car now recognizes, point out the dead-fob start method for your vehicle, and hand you an itemized receipt. If a spare makes sense, it's simplest to add it during this same visit while the equipment is already connected.

What affects the price of a K900 key

• 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.
• 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 Kia system adds equipment time and labor to the job.
• 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. Because we come to you, the distance from our San Bernardino base and the time of the call play a part. So does anything we find along the way, such as a worn ignition cylinder or a seized door lock. You hear about each item and get a quote before we start work.

Common Kia key problems

• Programming a new Kia key usually erases any key that isn't in the car at the time. If you add a spare and leave your other key at home, that key may stop starting the car, so bring every key and fob to the appointment.
• Parked-car temperatures in an Inland Empire summer drain coin cells faster than the package suggests. A fob that suddenly makes you walk right up to the car usually wants a fresh battery rather than a replacement.
• Most Kia fobs and flip keys take a CR2032, but newer designs, including the 2022-and-later Telluride, the refreshed K5 and Sorento, the K4 and later Carnival fobs, use the thicker CR2450. Read the cell printed inside before buying a replacement.

Tips from a mobile locksmith

• 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.
• 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.
• 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.

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.
