Mercedes benz c180 (w202) faulty vacuum pump, how to open the boot.

Mercedes Benz c180 classic 1.8 1998 (w202). The central locking was not working, I could not open the boot to get at the vacuum pump, there was no power as the battery was totally dead, I opened the door with the key on the FOB, opened the bonnet and connected a charger to the terminal block to charge the battery, the car started after charging but still couldn't open boot, so in this video I show you how to get into the boot to get to the vacuum pump to fix/test or remove and replace.
