European influenced cylinders with a thumb turn on the back side have become very popular in North America. The solution to opening these locks is the Sparrows Euro Driver. This two piece set covers the most popular sizes in left and right keyways. Simply side the driver through the keyway and turn the tailpiece opening the lock. With a long stem and permanent thermo plastic handles these all steel drivers have been polished smooth so they will slide through even narrow European cylinders. As with all of the SPARROWS products these are professional grade tools.
