Due to several years of use, one of the buttons on our IFB microwave oven has started malfunctioning - it starts and stops randomly due to the button getting pressed on its own. I think I heard one day some piece falling off the button internally. Now, I want to try to open up the front panel and fix whatever has broken on the button. However, I'm having a hard time figuring out how to do so - there are a couple of torx security screws I can see but I can't be sure if they are the correct screws to be removed. Also, I'd need to buy a driver bit for the security torx. I'm aware microwave ovens carry hazardous charges so I just want to work on the front panel.
Here are pictures of the oven, please let me know if you have any idea how the front panel can be opened up:
