🔑 Car Key & Fob FAQ

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

Security Systems
A flashing security light often indicates an immobilizer issue. Solid light suggests the system is armed but not recognizing your key. Causes: faulty key chip, damaged antenna ring, low battery, or system needs reprogramming.
Key Tip: Newer cars often require dealer programming for first key replacement
Lost Keys
Dealerships can often cut keys using your VIN, but will require proof of ownership. This only works for original factory keys - aftermarket or previously replaced locks won't match. The key will still need programming to start the car if it has a transponder.
Key Tip: Store your key code separately from your keys
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 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 Fob Issues
This typically indicates: weak fob battery (replace first), damaged fob antenna, or issues with your car's receiver (often in the door handle or rearview mirror). Environmental interference from other electronics can also reduce range.
Key Fact: Modern transponder keys have been required in all new US vehicles since 1998
