Is It Possible To Copy A Key From Your Voice?August 2020
As if we didn’t have enough to fear with the thought of lockpicks breaking into our homes, researchers at the National University of Singapore have revealed that by using a smartphone to record the sound of a key in a lock, thieves have all the information they need to make a working duplicate.
The research team found that the sounds made by the key as it hits specific pins, along with the timing of these sounds, within a tumbler lock can be reverse-engineered to determine the shape of the key, or at the very least a close match.
Thankfully, the technique isn’t completely foolproof. The SpiKey software requires a key to be inserted into a lock at a constant speed for the sound to be successfully analyzed and reverse-engineered.
