🔑 Car Key & Fob FAQ

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

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 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.
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: Avoid exposing key fobs to water or extreme temperatures
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: Newer cars often require dealer programming for first key replacement
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 Fact: Some insurance policies offer key replacement coverage
