My 2010 Mercury Mountaineer refuses to start. Could be the key code—trying this fix.

🔑 Car Key & Fob FAQ

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

Key Fob Issues
Sometimes. Broken buttons can often be fixed by cleaning or replacing the button pad. Cracked cases can be glued. However, water damage or circuit board issues usually require complete fob replacement. Reprogramming is still needed for replacement fobs.
Lost Keys
Costs vary widely: Basic keys: $50-$150, Transponder keys: $150-$300, Smart keys/fobs: $200-$800, Dealership replacements typically cost 20-50% more than locksmiths. Emergency/lockout service adds $50-$150.
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
You can buy fobs online, but: 1) Must match your exact model/year 2) Many still require professional programming 3) Cheap knockoffs may not work reliably. Some eBay/Amazon sellers offer programming instructions for DIY-friendly models.
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: Some locksmiths offer mobile key programming services
Key Fact: Modern transponder keys have been required in all new US vehicles since 1998
