Hi skoda octavia owners and skoda enthusiasts

Firstly I don't know if this topic needs to be here or in a general skoda page.

I am encountering an issue with my Skoda Octavia mk4 2023 model. On multiple occasions whilst park at work I've come back to find the car unlocked at the end of day. The first time or so I was unsure if I had locked it or not though I normality pay attention but the latest time which was today I knew I had as i made a mental note of it whilst walking away. Also I have the key fob in a Faraday pouch to block the signal. Now I can get paranoid and start thinking someone is able to have gotten access to the fob key and opening the car but i think that's highly unlikely though maybe not impossible. I'm thinking maybe it's more the car self unlocks. Not sure why or how. Has anyone else encountered this issue. It's baffling to me.

Does it only happen at work?

If so, it might be interference from either another car's key fob or some device within the premises - try parking in different areas and away from other cars.

If not, get the main dealer to sort it out.

Yes only at work, hard to park away from other cars as other cars are parked around. Specifically has happened when I've parked on the main highway road off the street as I haven't been able to find parking near work. Close to work itself or home it hasn't. Could it be other skodas passing by with their fobs automatically unlock the car. I didn't consider it. Maybe i should turn off automatic unlock but I do enjoy the feature and find it useful used to it. Thanks for the further advice re taking it to the dealer as well.
