Abstract

See full text

The disclosure is directed to the method of addition, in a fixed and inexpensive way, of a cylindrical sleeve to a key for an anti-theft wheel lug nut having a complementary key pattern formed on a surface thereof, and to the resulting key. The cylindrical sleeve of the key is formed separately from the key and then rigidly attached onto a groove formed in the key itself. The sleeve acts as a guide for the key and prevents the dismounting thereof during the torquing and untorquing of the complementary patterned lug nut.
