🔑 Car Key & Fob FAQ

Common questions about key programming, fob issues, and replacement options

Key Programming
Common reasons: wrong key type for your vehicle, anti-theft system needs reset, low car battery voltage during programming, or the key isn't properly synced. Some cars also have programming limits (only 2-4 keys can be registered).
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
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.
Security Systems
Some systems reset by: 1) Disconnecting battery for 15+ minutes 2) Using original keys in specific sequences 3) Professional diagnostic reset. Consult your manual - procedures vary. Persistent issues may require dealer-level tools.
