Kix Alarm System Fault

I had a similar problem in my Kix. The siren comms can be a pain. Did you check the physical connections to the siren module itself? Wiggle them and see if anything changes. It could be corrosion or a loose pin.

Where is the siren module located, and what connections should I inspect? Did you use a specific diagnostic procedure to disarm the alarm?

The module is usually tucked behind the wheel arch liner. Chasing these faults can be a headache. In my case, it was a bad connection inside the siren unit. Unless you're comfortable dismantling it, I'd recommend a workshop visit. Otherwise, you might trigger a security breach. This sounds very much like the same issue. If you go to the workshop, expect a ~95€ bill.

Thanks for confirming a similar experience. I'll get a professional inspection and potential repair. The workshop advice and cost estimate were helpful. Thanks again.
