Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
Key Fob Issues
This typically indicates: weak fob battery (replace first), damaged fob antenna, or issues with your car's receiver (often in the door handle or rearview mirror). Environmental interference from other electronics can also reduce range.
