Battery dead, discovered design flaw

[IrishGraeme]

Hi,
I am looking for some help with my RHD 2020 Leon.
I was away working for a year, and I left my car in a garage, I made the mistake of locking it.
The battery is dead but I was able to get in through the drivers door with the emergency key. I then tried to pull the bonnet release leaver to open the bonnet to put the battery on charge, but the lever is on the passenger side of the car and the door needs to be open for the lever to rotate.
I cannot open the passenger door, because its locked so I cannot open the bonnet. I cannot roll the car out of the garage because the handbrake is on and I cannot put it in neutral without power.

So for now my car is dead and stuck in my garage.

I am sure someone here has had a similar problem, can you please tell me how I get enough power in so I can open the passenger door?

Can you put power in through the OBD2 port? I cannot think of any other way of getting power in

power via the 12v socket & invest in a trickle charger

I did try that, but I got nothing. I figured the 12v socket was off when ignition was off. I will try it again. Any other ideas?

Move the fuse in the fusebox to switch the 12v from t15 to t30

So that will give me power back from the 12v socket ? Thank you
