🔑 Car Key & Fob FAQ

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

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 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 Tip: Avoid exposing key fobs to water or extreme temperatures
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.
Security Systems
This means your car's immobilizer system can't read the key's transponder. Causes: dead key battery, damaged transponder chip, faulty car antenna ring around ignition, or system needs resetting. Try replacing the battery first.
