🔑 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.
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 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: Replace key fob batteries every 1-2 years as preventative maintenance
Key Programming
Most transponder keys and smart keys can be reprogrammed if they haven't been damaged. Basic mechanical-only keys (no chip) can't be reprogrammed - they must be physically cut to match your locks.
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.
Key Fact: Key programming typically takes 15-30 minutes for professionals
