🔑 Car Key & Fob FAQ

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

Key Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
Key Tip: Always have at least two working keys to avoid expensive replacements
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.
Lost Keys
Yes, a skilled auto locksmith can extract the broken key and make a replacement. They can often do this without damaging the ignition cylinder. The new key will need programming if it has a transponder chip.
Key Tip: Store your key code separately from your keys
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
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 Tip: Always have at least two working keys to avoid expensive replacements
Key Fact: Key programming typically takes 15-30 minutes for professionals
