My Citroen C4 Picasso II is basically useless until I get this code. Fingers crossed.

🔑 Car Key & Fob FAQ

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

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.
Security Systems
A flashing security light often indicates an immobilizer issue. Solid light suggests the system is armed but not recognizing your key. Causes: faulty key chip, damaged antenna ring, low battery, or system needs reprogramming.
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 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 Fact: Some insurance policies offer key replacement coverage
