Key Tip: Some locksmiths offer mobile key programming services
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 Tip: Always have at least two working keys to avoid expensive replacements
Key Fact: Smart keys use radio frequencies between 125 kHz and 2.4 GHz
