🔑 Car Key & Fob FAQ

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

Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
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).

Lost Keys
Locksmiths or dealers can: 1) Decode your door or ignition lock to determine key cuts 2) Access your car's key code through manufacturer databases (with proof of ownership) 3) Program new transponder keys using diagnostic equipment.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
Key Tip: Store your key code separately from your keys
Key Fact: Smart keys use radio frequencies between 125 kHz and 2.4 GHz
