Lost Keys
1) Contact a locksmith who specializes in automotive keys or your dealership 2) Provide proof of ownership (registration, title, ID) 3) They'll either cut new keys by code or reprogram your car's system 4) This is expensive ($200-$800) as the immobilizer may need resetting.
Key Tip: Replace key fob batteries every 1-2 years as preventative maintenance
Lost Keys

Key Tip: Newer cars often require dealer programming for first key replacement
Key Fact: Modern transponder keys have been required in all new US vehicles since 1998
