Hyundai Key not Working - How to Start the Engine  

Which model?

Yo we're on side of road and this shit worked bro!!!!!!!!!

Put it in the port in the driver armrest. Can fix any connection issues

Thankyou sir

Yeah ok I do that anyway but I’ve changed the battery and it’s still not registering that I’ve done so? So how do I get it to register back to my car?

Yeah its really work

I’m having the same issue, it looks like the remote is a problem the batteries work as I can open the door whilst holding the keys and pressing the button on the handle and the electronic start works indicating it can find the key, but can’t unlock or lock remotely, so I think it’s an issue with the buttons on the key
