Key Tip: Avoid exposing key fobs to water or extreme temperatures
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: Replace key fob batteries every 1-2 years as preventative maintenance
