🔑 Car Key & Fob FAQ

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

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 Fob Issues
Sometimes. Broken buttons can often be fixed by cleaning or replacing the button pad. Cracked cases can be glued. However, water damage or circuit board issues usually require complete fob replacement. Reprogramming is still needed for replacement fobs.
Key Programming
Some vehicles allow DIY key programming using specific sequences (like turning ignition on/off with original keys). However, most modern cars require specialized equipment only locksmiths or dealers have. Check your owner's manual for your specific model.
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: Consider key insurance for expensive smart keys
Lost Keys
Locksmiths or dealers can: 1) Decode your door or ignition lock to determine key cuts 2) Access your car's key code through manufacturer databases (with proof of ownership) 3) Program new transponder keys using diagnostic equipment.
Key Tip: Store your key code separately from your keys
Key Fact: Some insurance policies offer key replacement coverage
