🔑 Car Key & Fob FAQ

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

Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Tip: Keep spare keys in a faraday bag to prevent signal amplification theft
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.
Key Tip: Store your key code separately from your keys
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).
Cost & Options
Locksmiths are typically 30-50% cheaper than dealerships for key replacement and programming. However, some newer models (especially luxury brands) may require dealer-only programming tools. Always get quotes from both.
Key Fact: Some insurance policies offer key replacement coverage
