<p>A lock having a housing with a socket and a cylinder plug inside the sock, the housing having a first row of outer locking holes 152 for receiving driver pins and a second row of locking holes 230, preferably also a third row, located radially around from the initial set of holes 130. This second set comprising relocker pins 240. The second and third row of outer pins prevent the plug 30 being rotated relative to the housing 20 to such an extent that the lock unlatches when it is bumped as the relocker pins engage with inner locking holes located in the plug. Preferably the radial width of the holes in the second and third rows of outer locking holes is narrower than the holes in the first row of locking holes. The relocker pins may have an upper part and a lower part, preferably each having an angled or slopping surface which engage with each other (Fig 4/5), the pins may also be shaped to prevent returning of the relocker pin (347 Fig 5).</p> |
