🔑 Car Key & Fob FAQ

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

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.
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.
Key Tip: Always have at least two working keys to avoid expensive replacements
Key Fob Issues
Many cars have a resync procedure: 1) Press lock/unlock buttons while near the car 2) Insert key and turn ignition on/off in a specific pattern 3) Use a sequence of button presses. Check your manual for exact steps - procedures vary widely by manufacturer.
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).
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: Replace key fob batteries every 1-2 years as preventative maintenance
Key Fact: Key programming typically takes 15-30 minutes for professionals
