A blocking tumbler pin pair, consisting of a standard coding pin (coding tumbler pin) and an extended standard blocking counter pin preventing the complete insertion of a key with a b'eekmc, poew v* ndr -,s n>v deep enough, n attmhed ai me seann.-st coding ρο-mot m the assigned cylinder. This blocking groove coding results in high permutation capacities. Such a horizontal blocking groove however is still not too difficult to copy or replicate.

The searefeed reference WO 3004/1)48724 discloses a backward compatible lock system of a different kind, with key blanks and turn keys therefore and with only one coding row / pin row with firs?, coding pins and first coding recesses as well as profile guide grooves, which form a cross section profile corresponding to a cylinder profile and a second kind of coding recesses,, whieh correspond to a second kind of ceding pin. This second coding pin is non-circularly symmetric, but nofittveh guided and it comprises segments v.uk differed shapes; ?uo cuter and one inner segment, whereby the outer segments nf the second ending pm eouespond to boo additional grooves at. a coding position of the second hhtri on -he kc> With the second kino coding an additional rotation block with respect to the shear line can be ehected With the key blanks, keys and cylinders of WO .20()4/048724 the following obicet ot the present invention ant o' be e ewd \od o .ucata h n'AO OtU fUS ? 1 then, s no uhee, e 5 a, , ,m insertion block at the key tip by means of an extended counter pin.

Igénypont szerinti eljárás, azzal jellemezve, hegy a nyerskuloson először első maróval a kódoló tartományban (RB-R) egy lesüllyesztett középső bordát (RB-M(2)) állítunk elő, és ezt követően második maróval az oidalhornyokaf (RS-BR) a bemeneti tartományban: (RB-E) magas szinten ΒΜΈ a kódoló tartományban (RB-P) pedig mélyebb szinten (N2) állítjuk elő, IS. A 17, igénypont szértnil eljárás, ázzál jelbmezvo, hogy a nyerskulcson nullánál nagyobb hajlásszögben (Wa) hajló zárőeiem: óiknál (A) először első maróval a süllyesztett középső: hordát és egy járulékos mellékhernyot (RB-nn) állítunk elő.16. A method according to claims 9-14. The key (S) according to any one of claims 1 to 3, wherein said key (S) is selected from the group consisting of: A method for producing a raw slice according to any one of claims 1 to 3, characterized in that the raw slice IR is in the input region (RB-E) by cutting the middle rib (RB-M) in a central groove (RB-MN) and in the coding region (RB-P). ) we make recesses (Öod-V) encoding the first coding positions (Bt, P2), 17 «The shoot. The method according to claim 1, wherein the hill is first formed by a first milling cutter in the coding region (RB-R), and a second milling cutter (RS-BR) is used to produce the recessed center rib (RB-M (2)). in the range: (RB-E) is produced at a high level oló in the coding region (RB-P) at a deeper level (N2), IS. The method of claim 17, characterized by the fact that the closing element at an angle of inclination (Wa) greater than zero on the key is first produced by the first milling cutter, the recessed center: the mandrel and the ancillary sub-groove (RB-nn).
