A person approaches the entrance, opens the door with an electronic lock, goes up the stairs, opens the door to the apartment, enters and writes down the lock. Recorder: tascam dr-40. Recorded at 2016-03-24.
This a simple sound i recorded from my "master lock hard case" combination lock. I used audacity for noise reduction and editing. I couldn't find a good, free combination lock sound, so i decided to make my own :).
Captured during a windstorm. Door opens and swings out and the white noise of the storm is all there is, until the door swings back and thumps closed, then the dead bolt slides lock.
Unlocking the safety frontdoor with keys needs more than one turn. Then closing and locking it again. The second unlock has a pause before the mechanism finally unlocks the door. At the end the door is getting locked from the inside with keys.
