Not sure if I am asking the right question, But I haven't even had my car a full year and I am possibly having issues with my keyless remote fob I believe. When I click to lock or unlock it doesn't respond, nor does it start my car. with that being said, 1. does this mean i need to change the battery? 2. if i change the battery will this help my car to start, or will it have to be reprogrammed?


I have no experience with your model Hyundai.

However, the first thing to try with a non-working (or now-and-then non-working) remote is to remove its battery, buy a new battery of the correct type, clean both the battery contacts in the remote as well as the battery faces, then install the new battery in the remote. That should restore the remote to operability, i.e., it'll transmit when its buttons are pushed. Changing only the remote battery may not require re-pairing the remote with the car.

  • Many fobs need re-pairing after removing their battery or batteries... My car definitely does... – Solar Mike Dec 12 '18 at 6:49
  • @SolarMike Certainly, that's why I said "many." I've had this issue on VWs and Hondas, and found re-pairing unnecessary. In any event, making sure the remote's battery is good and its connections clean is still the proper first step. – David Dec 12 '18 at 15:09
  • can’t see « many » in your answer... I do see « unlikely » which is what I did not agree with ... I, from experience, find it necessary to re-pair the keys and that tends to mean all keys associated to that car... – Solar Mike Dec 12 '18 at 15:57
  • @SolarMike I changed "unlikely" to "may not." – David Dec 12 '18 at 15:59
