Mr Zeytoonian, if you are referring to your key fob, so long as it is a factory Chrysler Jeep Dodge Ram or Fiat fob we can help you. Feel free to give our service department with more details to be certain.
If it is only a single bitton it can possibly be fixed by taking it apart and ensuring the internal contact is centerd on board. Batteries are easy. If it is a chipped fob only use OEM replacements as aftermarket have been less than successful for me.
If it's not the battery, your best bet is ordering a new one online or at a dealer
