Simply Diagnostics provides a masterclass in systematic troubleshooting for intermittent remote locking and hands-free starting failures on a 2016 Citroen C4 Picasso.
This example highlights the critical importance of verifying correct component variants, even when diagnostic trouble codes suggest otherwise.
Steve Scott demonstrates why relying on OEM technical data and expert collaboration is essential when working with salvaged or unverified parts.
By using precise scanning tools and cross-referencing vehicle configuration data, the team successfully identified an incorrect key variant rather than an electrical fault.
This technical breakdown offers valuable insight for any workshop navigating complex immobiliser and key programming challenges.
