This is probably a complete newbie question, but I've searched and can't find the "correct" answer anywhere (have tried 10+ methods I've found online and none have worked).

I have a 2013 Elantra Limited Sedan. It came with the Hyundai factory remote start key fob. The batteries died so I replaced them with 2 new duracell units. The fob no longer works to lock, unlock, or start the car. The 2nd remote start fob that I have works without issue...so I'm guessing the one that I replaced the batteries in needs to be reset or re-synch'd with the car? Does anyone know the correct method for accomplishing this?

The style of OEM Hyundai remote start/unlock fob I have is pictured below. Thanks for any help!

I would check and make sure the battery is placed correctly in the fob. I had a similar problem and had placed the polarity incorrectly!

I've tried the batteries in all different polarities....same result for all unfortunately.

When I do have the batteries in at the correct polarity tho, the little "LED-1" light at the top of the board blinks 10 times...wish I could find what that means :( - pic of the LED below:

No idea here either!! Sorry!
No worries, appreciate the idea to try different battery orientation. I asked the question on some FB groups too - its looking like I may have to take it to a dealer for the synch $$$$ :(
