Arkana central locking problem

Hmm, that's odd. Does the car alarm still work? And what about keyless entry, if you have it? Could be a fuse, but since there's an error code, maybe something more complex. Have you checked all the door lock connections?

The car alarm seems to be working, yes, but the keyless entry is also dead. Where exactly should I check the door lock connections? I'm not very experienced with this.

Ok, keyless entry also not working points away from a simple fuse. The error code plus both failing makes me think it might be a bad connection, like a cable or plug somewhere in the locking mechanism circuit. Honestly, with that kind of issue, it's best to get it checked by a workshop. I heard that the repair can be around 95€.

Thanks for the info! I will take it to a workshop as you suggested. They checked the error memory and told me that a cable or plug connection of the component is defective. I'll let you know how it goes!
