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

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: Consider key insurance for expensive smart keys
Key Programming
Programming syncs the key's transponder chip with your car's immobilizer system. The process varies by manufacturer but generally involves: 1) authenticating with the car's computer 2) erasing old keys if needed 3) programming new key codes 4) testing functionality.
Key Tip: Always have at least two working keys to avoid expensive replacements
