Why BASI?
BASI is a German security technology company based in Mönchengladbach, founded in 1981. The company specializes in the development and production of locking systems and offers a wide product range.
Emergency and hazard function
BASI keys, especially the patented systems (such as K6-RT, T250 or KS-2), offer active copy protection through special control elements in the key profile or in the cylinder (e.g. cross slide, freely mounted locking ball).
Large selection
BASI locking systems are manufactured from high-quality materials such as nickel silver (for key blanks) and brass (for cylinder bodies and cores). Hard bronze and special brass pins ensure durability and reliable function.
High-quality material
BASI offers a wide range of locking cylinders (half, double, knob, external and lever cylinders) and locking systems suitable for various applications (front doors, interior doors, garages, mailboxes, etc.).
High copy protection
Many BASI double cylinders can be optionally equipped with an emergency and danger function (E+G). This means that the door can be opened from the outside even if a key is already in the lock on the inside.

BASI keys copied in Vienna
First, we need your original key. This is clamped into a high-precision milling machine. The machine scans the key's unique profile and creates milling patterns accurate to the millimeter.
This precise shape is then transferred to a new key blank. The machine mills the necessary patterns in reverse to ensure a perfect copy of your original.
