Hello,

I would like to apologize in advance if this is not a new topic, but I couldn't find any help . I changed the key fob with new one. The key itself is the original including all electronics inside the fob. Now after replacement, the remote works just fine and locks/unlocks the car, it cranks, but it won't start.

Any suggestions please?

Thanks very much

Please tell me nothing has been thrown out yet.

Transponder chip swapped over from old casing to new? It's in the corner encapsulated in a triangular like white plastic holder.

I didn't throw it, it's also in the new fob. It's not damaged, as I moved it out and put in carefully.

OK, now I see from the short video, that below the white plastic, there is something else to be replaced, right?

So what you are saying is the original Transponder chip was removed from old case and installed in new case?

Any chance you can open up new key fob again and take image, then post that image here please so I can see where it's sitting?

You will see "click here to add an image to this post" below the reply window.

If car started just prior to this and chip has been swapped over it should function as before.

Did the new fob have a new chip or is it a bare case?

I can't see how the chip would fail with the transfer. done this myself with no issues.

Is the immobiliser icon flashing when it fails to start?

Can you give me time reference on video so I can see what you see?

The black transponder chip like the image I posted?

[sofiyanski]

Unfortunatelly I don't have the fob with me now, cause I left it at a friend's house.
The black chip (I suppose) is in 2:04 from the video How to Open and Replace Shell of Hyundai/KIA i30/i20/Elantra Car Key Case - YouTube

This black thing I didn't replace...

You may wish to make a call to your friend and make sure whatever is left of your old casing is not in the bin.


If it's lost, you will need a new blank chip, Dealer level programmer and PIN access code to program new chip .

Vehicle locksmith would also have that equipment.

I already called him and it's in safe place
Now, just to make sure, after I put everything in place, including the black chip, would it work without issues?

It's not starting because the immobiliser is not seeing a valid transponder chip. orange flashing key icon also likely in instrument cluster.

This way people can't just cut a key and drive off with the car.

Pure and simply yes it will start if that chip goes back inside that case in the same location. try and fit the white cap over it like it was too may help keep it there.

its an easy mistake to make. Did it myself, the chip dropped out as I reassembled the key.    Yep I had swept the workshop floor.
