Hyundai Elantra key fob malfunction due to ignition switch issue preventing door locking and trunk access on Hyundai Elantra

Some Hyundai Elantra owners report experiencing key fob malfunctions that prevent door locking and trunk access, often attributed to a dead coin battery inside the key fob. These issues can lead to difficulties in opening or closing doors, as well as non-responsive door locks. Many owners find that replacing the battery is a straightforward fix, following guidance from the owner's manual or online resources. However, some may encounter complications if they attempt DIY methods to access locked keys in the trunk, which could potentially damage the vehicle. Additionally, proper care of the key fob is essential to prevent connection failures and extend its lifespan. Owners have also noted that problems with door plungers or push switches can affect the locking mechanism of the Elantra. Overall, while ignition switch issues can affect vehicle functionality, key fob malfunctions are more commonly linked to battery problems and other key fob-related concerns.
