🔑 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.
Security Systems
Not recommended. Bypassing requires specialized knowledge and may violate anti-theft laws. Proper solutions: 1) Get correctly programmed keys 2) Replace faulty immobilizer components 3) Have dealer reset the system if keys are lost.
Key Tip: Consider key insurance for expensive smart keys
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.
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: Newer cars often require dealer programming for first key replacement
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 Fact: Modern transponder keys have been required in all new US vehicles since 1998
