🔑 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
This typically indicates: weak fob battery (replace first), damaged fob antenna, or issues with your car's receiver (often in the door handle or rearview mirror). Environmental interference from other electronics can also reduce range.
Key Tip: Newer cars often require dealer programming for first key replacement
Key Fob Issues
1) Find the seam and pry open the fob (some have tiny screws) 2) Note battery orientation 3) Remove old battery (CR2032 is most common) 4) Insert new battery 5) Reassemble. Test all buttons - if issues remain, the fob may need reprogramming.
Key Tip: Store your key code separately from your keys
Key Fob Issues
Common causes: dead battery (most common), water damage, internal circuit damage, or the fob lost synchronization with your car. Try replacing the battery first. If that doesn't help, the fob may need reprogramming or replacement.
