Re: [SERIOUS] How to detect if a door is opened or not ?
If I were you I'd change the lock. What type of lock is it? Cylinder locks are most common in my country: http://en.wikipedia.org/wiki/Cylinder_lock
They are very cheap and easy to change. A new cylinder (with 5-6 keys) costs $1-$1.5, changing it invovles unscrewing one screw (shown on picture) sliding in the new cyilinder and screwing it back in. Even if you have never done it before it wont take you more than 2-3 minutes.
That way you are certain that noone else has the key.
