🔐 Ford Transit Pin Code Immobiliser with Built-In Alarm. In this video I demonstrate a CAN bus pin code immobiliser installed on a Ford Transit, with an added alarm function using the vehicle horn. From the moment the ignition is switched on, a 15-second timer starts. If the correct authentication isn’t detected within that time, the vehicle horn sounds, turning the immobiliser into an effective audible alarm and theft deterrent.

The alarm can be stopped in three ways:

✔ Entering the custom PIN code using the vehicle controls
✔ Having the paired security tag with you
✔ Having your paired mobile phone nearby

This system offers serious security for under £600 — sitting perfectly between a basic pin code immobiliser and an expensive smart alarm system. 💡 Remember: Good security should make noise. If you're looking for a practical and affordable way to protect your Ford Transit, this setup is definitely worth considering.
