Both FOBs not working - Hyundai Forum - Hyundai Enthusiast Forums

Hyundai Elantra While not much larger than the accent, the Elantra offers similar room, but a sportier look and feel, as well as more power.

If you have no way of checking the batteries in the FOBs , why not try replacing the battery in one of them and see what you get ?

Had a similar problem and found the batteries and contacts corroded. But I live in high humidity Florida so we live with that problem. I used a little dielectric grease on the contacts when I installed the new batteries to prevent the problem in the future.
