Is the FCC ID enough to verify the fitment of the 95440-1W101?

No. FCC ID SY5XMFNA04 is printed on the 95440-1W101, the Optima key 95440-2T510 and the Sorento key 95440-1U500, so one approval covers several parts. Use the part number on the label and the four-button pad with a trunk icon as the match.

Which cars does the Kia 95440-1W101 smart key fit?

The 95440-1W101 is the Kia catalogue key for the North American 2014-2017 Rio with push-button start. Interchange lists also run it on the 2014-2015 Optima in place of 95440-2T510, on 315 MHz cars only. Check the number on the customer's original fob first.

Is the 95440-1W101 a 315 MHz or a 433 MHz key?

It works at 315 MHz, the North American frequency of FCC ID SY5XMFNA04. Some 2014-2015 Optima cars came with a 433 MHz key instead, 95440-2T500 on SY5XMFNA433, and a key on the wrong frequency will not open or start that car.

What transponder chip does the 95440-1W101 use?

The 95440-1W101 carries a HITAG 2 ID46 transponder from the PCF7952 family, the same chip as the other SY5XMFNA04 keys. The part number, FCC ID SY5XMFNA04 and the four-button trunk layout are the references, and the key tool reads the immobiliser during registration.

Does the 95440-1W101 come with an emergency key?

No. The 95440-1W101 is supplied as the smart key fob only, new in the Kia box with a CR2032 battery fitted. Order the Rio emergency insert key separately and cut it to the vehicle code, so the driver can still open the door with a flat fob.

How do I program the Kia 95440-1W101 to a Rio?

Program the 95440-1W101 through the OBD port with a key tool that lists the 2014-2017 Rio, such as Autel IM608, Lonsdor K518 or Abrites AVDI. The tool needs the immobiliser PIN, read through OBD where supported or obtained from Kia by VIN.

Will the customer's other Rio keys still work after programming?

Only if they are registered in the same session. Adding a 95440-1W101 rewrites the stored key list, so a fob that is not presented stops starting the car. Ask the customer to bring every key they want to keep and register them all together.

⭐ Kia part 95440-1W101 is the 4-button, 315 MHz proximity smart key for the North American 2014-2017 Kia Rio, approved under FCC ID SY5XMFNA04. Lock and Unlock sit at the top, the trunk button needs a press and hold, and the red Panic button closes the pad. The same approval number is printed on the Optima key 95440-2T510 and the Sorento key 95440-1U500, which is why the 1W101 on the label, and not the FCC ID, decides the order. Catalogue interchange lists also run this key on the 2014-2015 Optima. It is a genuine Kia factory unit, new in the Kia box, without the emergency insert key.

⚙️ Key features

315 MHz North American build

SY5XMFNA04 is a 315 MHz approval. 433 MHz Kia keys from the same years will not work in its place.

Trunk on a long press

The boot release carries a HOLD mark, so a pocket press does not open it. Panic sits at the bottom in red.

Not the Sorento key

Sorento key 95440-1U500 carries the same FCC ID with a hatch button. It is a different part number.

Continental board

The fob back carries the Continental sticker with the short code 1W101 printed on it.

💎 Benefits

One number to check

The fob sticker and the Kia box both carry 1W101, so the counter check is a straight comparison.

Finished at the car

A key tool with Rio smart key coverage registers the fob through the OBD port on the same visit.

Familiar pad for the driver

The owner gets back the same four buttons and the same black and chrome case.

👥 Who it's for

Spare-key and all-keys-lost calls on North American Rio cars with push-button start.

Key shops and counter trade

Rio owners who bring in a cracked or lost 1W101 fob and want the factory part.

🛠️ Programming instructions

🔌OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

The Rio has no on-board routine for this fob. It is registered through the OBD-II port with a key tool that covers the 2014-2017 Rio smart key system, using the immobiliser PIN.

Compatible tools: Autel IM508 / IM608, Lonsdor K518, Abrites AVDI with the Hyundai / Kia PIN and key manager, or the Kia dealer system, where the current software lists the Rio.

Add key (spare): get the PIN (read through OBD where the tool supports it, or from Kia by VIN), then register the new 1W101 with every key the customer keeps.

All Keys Lost: the same PIN registration with no working fob. Hold each fob to the start button when the tool prompts, and cut the emergency key separately.

Check coverage first: Rio and Optima coverage depends on the tool brand, its software version and the market the car was built for. Look up the exact model year in your tool before the job.
