Claims (10)

6 169584/3 C L A I M S What is claimed is:
1. A keying system comprising: a cylinder lock comprising a tumbler having a keyway and tumbler pins, driver pins being disposed in said cylinder lock; and a master key element disposed in said cylinder lock that forms together with said tumbler pins and said driver pins a master key combination alignable with a shear line by insertion of a master key into the keyway, said tumbler being rotatable along said shear line; characterized by an intermediate key, which when inserted in said keyway, aligns said tumbler pins, said driver pins and said master key element with the shear line to permit rotation of said tumbler, and displaces said master key element so that said master key element is no longer alignable with the shear line by means of said master key, wherein said intermediate key is formed with a recess and said at least one of the driver pins is biased against said master key element by a biasing device, wherein when said intermediate key is inserted in said keyway, said biasing device urges said master key element into said recess, and wherein said master key element is a rod-shaped element that lies over three out of a total of five driver pins.
2. The keying system according to claim 1, wherein said intermediate key is adapted to displace said master key element to a position that permits removal of said master key element from said cylinder lock.
3. The keying system according to claim 2, wherein after removal of said master key element from said cylinder lock said intermediate key does not align said tumbler pins and said driver pins with the shear line to permit rotation of said tumbler.
4. The keying system according to any of claims 1-3, wherein said master key element is positioned between said tumbler and at least one of said driver pins, wherein that at least one of the driver pins does not participate in alignment with the shear line upon insertion of said master key into said keyway.
5. The keying system according to any of claims 1-4, wherein after insertion of said intermediate key into said keyway, rotation of said intermediate key moves said master key element away from its position between said tumbler and said at least one of said driver pins and permits removal of said master key element from said cylinder lock.
6. A method for master keying comprising: 7 169584/3 providing a master key that operates a plurality of cylinder locks, each cylinder lock comprising a tumbler having a keyway and tumbler pins, driver pins being disposed in said cylinder lock, wherein a master key element is disposed in said cylinder lock that forms together with said tumbler pins and said driver pins a master key combination alignable with a shear line by insertion of the master key into the keyway, said tumbler being rotatable along said shear line; characterized by providing an intermediate key, which when inserted in said keyway, aligns said tumbler pins, said driver pins and said master key element with the shear line to permit rotation of said tumbler, and displaces said master key element so that said master key element is no longer alignable with the shear line by means of said master key, wherein said intermediate key is formed with a recess and said at least one of the driver pins is biased against said master key element by a biasing device, wherein when said intermediate key is inserted in said keyway, said biasing device urges said master key element into said recess, and wherein said master key element is a rod-shaped element that lies over three out of a total of five driver pins.
7. The method according to claim 6, wherein said intermediate key is adapted to displace said master key element to a position that permits removal of said master key element from said cylinder lock, and further comprising using said intermediate key to remove said master key element from said cylinder lock.
8. The method according to claim 7, further comprising providing an occupant key, which after removal of said master key element from said cylinder lock, aligns said tumbler pins and said driver pins with the shear line to permit rotation of said tumbler.
9. The keying system according to any of claims 1-5, substantially as shown and described hereinabove.
10. The method according to any of claims 6-8, substantially as shown and described hereinabove. For the Applicant, David Klein Dekel Patent Ltd.
