Qashqai anti theft alarm malfunction

I understand you're encountering issues with your Nissan Qashqai's anti-theft system. Could you elaborate on the specific error code stored in the memory? Also, have you observed any unusual behavior prior to the system completely failing? These details might assist in narrowing down the potential causes.

Thanks for the quick response. Unfortunately, I don't have the exact error code to hand. However, it seems plausible that it's a coding issue as the alarm went haywire after a service. Is there any chance the optical locking feature might be linked, or am I barking up the wrong tree?

Given the alarm's behavior following a service, and your suspicion of a coding issue related to optical locking, it is conceivable that a misconfiguration is the source of the problem. While I cannot definitively confirm this, I highly recommend consulting a qualified technician. This will most likely require diagnostic equipment.

Appreciate the advice. Took it to a workshop, and you were spot on. The alarm was indeed coded to activate optical locking, which was causing the malfunction. Recoding the system fixed it - cost me 45€ Thanks again.
