Clio alarm malfunction

I'm having trouble with my 2004 Renault Clio diesel. The anti-theft alarm system seems to have gone haywire. There's an error stored in the memory, and the alarm itself is completely non-functional. I've checked the fuses, but everything seems fine. Any ideas?

I had a similar issue with my Clio. Does your alarm system activate the hazard lights when it's supposed to arm? It might be coded to activate optical locking but it has failed.

That's interesting. How would I check that? Is there a way to recode it myself, or is it something I need to take to a shop for?

In my case, yes, the indicators were supposed to flash but weren't. Honestly, I'd recommend going to a workshop with the error description. They should be able to diagnose and fix it quickly.

Thanks for the advice! Turns out the alarm system was indeed coded to activate the indicators for locking, and that was the issue. Workshop sorted it out for 45€. Appreciate the help!
