From Tardis Wiki, the free Doctor Who reference
The sonic screwdriver was a highly versatile tool used by many, but not all, incarnations of the Doctor. While early versions were used mainly for the picking of locks and for projecting sound so as to, for example, detonate bombs, by the time of the Ninth Doctor, the sonic was able to also be used as a sophisticated scanning device, with medical applications. Subsequent incarnations gave it even wider functionality, such as the ability to hack into computers, provide geolocation and actively defend against some types of assault weapon.
