🔑 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: Consider key insurance for expensive smart keys
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.
Cost & Options
1) Always have at least 2 working keys 2) Get spares made before losing originals 3) Consider key insurance/add-on coverage 4) Store key codes safely 5) Use protective cases for smart keys 6) Program new keys before old ones fail completely.
Cost & Options
Quality aftermarket keys work well for most vehicles at lower cost. However, some luxury brands use proprietary technology only available through dealers. For expensive cars, OEM may be worth the extra cost for reliability.
Key Tip: Store your key code separately from your keys
