Which Sonata models does 95440-L1210 fit?

It fits the eighth-generation Hyundai Sonata from 2020 to 2021 with the smart key system, push button start and remote start, in 433 MHz markets. Hyundai used other smart keys on this Sonata, so match 95440-L1210 and FCC ID TQ8-FOB-4F26 on the label.

Can a used Hyundai smart key be programmed to another car?

Yes, after renewal. A registered Hyundai smart key stays locked to its first car, so it must be returned to a blank state on a tool that supports renewal for this key. After that it registers like a new key through the OBD-II port.

How does remote start work on this key?

Lock the doors near the car, then within about four seconds hold the remote start button on the 95440-L1210 key for around two seconds. Remote start works only on Sonata cars built with it; on other cars the button does nothing at all.

Is the emergency key included?

No. This listing is the used 95440-L1210 smart key only, with no emergency key and no original packaging. Reuse the customer's existing emergency key, or source one separately and cut it to the vehicle before the key is handed back to the customer.

How is the 95440-L1210 key programmed?

Over OBD with a key tool such as Autel IM508 or IM608, Xhorse Key Tool Plus, Lonsdor K518 or OBDSTAR, after renewal. The registration needs the vehicle PIN code, which the tool reads or calculates online, or the dealer supplies. There is no on-board routine.

What happens to the old keys during registration?

Hyundai smart key registration rewrites the list of keys stored in the car. Bring every key the customer wants to keep and register them in the same session together with the renewed 95440-L1210 key, or the keys left out can stop working afterwards.

Which transponder does the 95440-L1210 key use?

The 95440-L1210 key carries a HITAG 3 (ID47) transponder on the board, the chip family Hyundai used on this Sonata generation. No separate chip is needed, but the used key must be renewed and registered to the car before it will start the engine.

🛠️ Programming instructions

OBD PROGRAMMING - DIAGNOSTIC TOOL REQUIRED

A proximity key on the Hyundai smart key system. There is no on-board routine; the renewed key is registered through the OBD-II port.

Compatible tools: Autel IM508 / IM608, Xhorse Key Tool Plus, Lonsdor K518, OBDSTAR key programmers, or the dealer diagnostic system.

Renew first: a used Hyundai smart key stays locked to the car it was registered to. Renew it on a tool that supports this key before registration.

Add key (spare): the registration needs the vehicle PIN code; depending on the tool it is read, calculated online or supplied by the dealer. Present every key during the session.

All keys lost: the same smart key registration runs with the renewed key and any new keys, once the PIN is available. Test every button and the engine start.

Check coverage first: support depends on the tool brand, its software version and the exact model year. Check the 2020-2021 Sonata smart key and its renewal are in the tool's list before the job.
