Opel Astra H - Ignition Won't Start

Hi there. I am having quite a strange issue with my Opel Astra H 2004 1.8P Z18XE, and I was kind of hoping that someone going through the same or a similar experience could point me in the right direction.

The issue started a couple of weeks ago and is intermittent. It has happened only 3 times so far, but I am worried that it might leave me stranded or stop working in the middle of the drive. Any input is highly appreciated. I will attach a video demonstrating below. I would place the key in the ignition keyhole and turn it, but nothing happens.

A couple of layman deductions:

-The keyhole "feels" alright and turns just fine, but the ignition "contact" doesn't seem to be picked up by the car at all.

-It happened on both of my keys, so I wouldn't think it's the key. I also regularly change the key fob batteries. It isn't the battery/alternator, as other aspects requiring power work just fine.

-I wouldn't say it's the transponder. On occasion, I've had the card give me the transponder error, and it is quite distinct in terms of the sound and the warning light (the board would still light up).

-All three times the issue was resolved by me jiggling around with the steering wheel column. Last time I just placed upwards pressure from underneath the steering wheel (pulled it up essentially), and it got the "contact."

So far I've only tried using contact spray to clean the ignition keyhole and the key. I've also taken the top part of the steering column apart and fastened the main bolt, and the entire steering wheel has become a bit loose over the years, but none of these appears to have helped, as I am still experiencing the issue.

Sorry for the long post. This is quite important for me, so I've shared everything that I've gathered up until this point.
