Trying to FIX things around the Home - PART 3

Hi, this video shows me 'trying to fix' various faulty things around the home. A lot of the fixes may be very simple but if they are not tackled in time they can lead to bigger problems.
The time stamps are below -
0:51 - VW Golf Key FOB battery
3:13 - Zanussi Oven Door Seal
7:16 - Doorbell lost it's Ding
11:11 - Bathroom en suite LED Light replacement and cabinet loose cover/capping.
Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things.
I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series.
Many thanks, Vince :-)
