⭐ The 95440-M6840 is Kia's 4-button, 433 MHz smart key with remote start for the 2022 Cerato, the facelifted BD sedan with the new Kia emblem. It uses a HITAG AES ID 4A transponder, and the chrome edge carries Lock, Unlock, a remote start button and a Trunk button, both of the last two working on a long press. There is no Panic button, and the car must have the factory remote start function for that button to do anything. The fob arrives new and sealed in Kia packaging; the insert key is a separate purchase.

⚙️ Key features

Remote start on the edge

A circular-arrow button marked HOLD starts the engine from outside the car on cars with factory remote start.

HITAG AES ID 4A

The NXP 128-bit AES transponder family used on late Kia smart keys.

Side-strip layout

Four buttons on the chrome edge, the face left plain apart from the new Kia emblem.

CR2032 cell

The common 3 V coin cell runs the remote, the proximity entry and the remote start signal.

💎 Benefits

Cabin ready before the drive

Remote start lets the owner run the engine and climate control before getting in.

Number on the box

The Kia label reads 95440 M6840, so the part is checked at the counter before it is opened.

Same four functions

The replacement keeps remote start and the hold-to-open trunk of the original key.

Spare and lost-key jobs on 2022 Cerato sedans with remote start.

🛠️ Programming instructions

🔌OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

The 2022 Cerato registers this HITAG AES key through the OBD-II port. The tool needs the immobiliser PIN, and registration replaces the stored key list.

Compatible tools: Autel IM608 Pro, Lonsdor K518 Pro, OBDSTAR X300 Classic, Xhorse Key Tool Plus or the Kia dealer system, with the facelifted Cerato smart key in coverage.
Add key (spare): enter the PIN, choose smart key learning, then present the M6840 and every working fob at the start button.
All Keys Lost: no working key, so the PIN is read from the car where the tool allows it, or obtained by VIN or online calculation. Register each fob in turn and finish by cutting the insert key.
Check coverage first: AES coverage for the 2022 Cerato depends on the tool brand, its software version and any online service it needs. Check the tool list before the job.

Frequently Asked Questions

Common questions about this product

The 95440-M6840 is the 4-button smart key for the 2022 Kia Cerato with push-button start and factory remote start. It works at 433 MHz with a HITAG AES ID 4A transponder. Check the part number printed on the customer's existing fob before ordering.
No. The four edge buttons of the 95440-M6840 are Lock, Unlock, remote start and Trunk, and the last two work on a long press. A customer who expects a red Panic button needs another part number, so compare the button layout with the original key.
Only on a Cerato built with factory remote start. The 95440-M6840 sends the start command, but the car must have the function from the factory. On a car without it, the key still locks, unlocks, opens the trunk and starts from the push button.
No FCC ID is published for the 95440-M6840 in this listing, because no approval number could be tied to this exact part number. Match the key by its part number, the remote start button and the four-button edge pad on the customer's original fob.
The 95440-M6840 uses a HITAG AES ID 4A transponder, the NXP 128-bit AES family found on late Kia smart keys. The chip is part of the fob, so the key tool registers it together with the remote when it learns the key over OBD.
The 95440-M6840 is learnt over the OBD-II port with a tool that covers the 2022 Cerato, such as Autel IM608 Pro or Lonsdor K518 Pro. The car needs its immobiliser PIN, and an all-keys-lost job may need an online PIN calculation.
No. The box holds the 95440-M6840 fob, new, with its CR2032 cell installed, and nothing else. For a flat battery the car still opens with the Cerato emergency insert key, which is ordered on its own and cut to the vehicle code.
