🔑 Car Key & Fob FAQ

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

Key Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
Key Programming
Professional key programming requires: diagnostic tools to access the immobilizer system, key code software, transponder programmers, and often proprietary manufacturer equipment. Some locksmiths and all dealers have these tools.
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.
Key Tip: Some locksmiths offer mobile key programming services
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 Tip: Store your key code separately from your keys
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: Always have at least two working keys to avoid expensive replacements
Key Fact: Key programming typically takes 15-30 minutes for professionals
