Abstract (en)
[origin: ES480131A1] A key for a safety lock having two grooves on each flat side with pairs of identical grooves being located symmetrically opposed about the central axis of the key profile. The grooves (2,3) and the tumbler cams are fashioned in pairs with different dimensions, for the purpose of increasing the number of possible combinations. Thus, both the width and/or depth of a groove may be constant or variable.
