Still Having Trouble?

If you’ve replaced the battery and your 2018 Hyundai Tucson key fob is still not working properly, there could be other issues at play.

“Sometimes, it’s not the battery itself but the contacts inside the key fob that can cause issues,” says John Smith, Senior Automotive Technician at Car Clinic. “Over time, these contacts can become corroded or dirty, preventing a good connection.”

If you suspect this might be the case, you can try cleaning the contacts with a cotton swab and some rubbing alcohol. If the problem persists, it’s best to consult a qualified automotive locksmith or your Hyundai dealership for further assistance.
