Hello Internet! Today I want to tell you a little tip that will save you some money... i.e. the cost of a call to locksmith :) Did ever happen to you to lock out of your appartment? In many countries apartment doors have handles only on the inside, so if you go out (without the key ) and your door closes after you, you are screwed! Personally I did happen to me twice in the last 8 months :( Anyway, the easiest way (the one I used!) to unlock your door is with a credit card or, better, a loyalty card from a supermarket, because it could be damaged in the process! Then, the only thing you have to do, is to insert the card just next the knob and push ! That's it! After some practice, it works :) However, I have to tell you a couple of things... 1) Not all doors can be opened this way. 2) If you don't have a loyalty card to use, your neighbor certainly has it! This nice video explains it better that I did! There are also other ways to open a door without keys ,...
