Claim:
A lock and key combination including a lock ( 200 ) of the kind comprising: a housing ( 204 ) having a cylindrical bore ( 203 ), a cylindrical key plug ( 202 ) being rotatably journalled in said cylindrical bore, said key plug having a longitudinal key slot ( 201 ) and a number of locking pins ( 205 a - 205 h ) in a single row along a key plug axis for locking the key plug against rotation in the cylindrical bore, each locking pin in said single row comprising a body part ( 209 ) being guided for elevational movement in a cylindrical chamber ( 250 a - 250 h ), and a key sensing part ( 207 , 208 ; 210 , 207 , 208 ) projecting downwards from said body part for contacting one or more code patterns ( 103 , 104 ) on a key, and a key ( 100 ) of the kind comprising: a longitudinally extending, substantially flat key blade ( 102 ), which is insertable into said key slot in the key plug of said lock, at least two longitudinally extending formations on said key blade, forming said code patterns ( 103 , 104 ), wherein said key blade comprises an upper portion having a first code pattern ( 103 ) and a lower portion having a second code pattern ( 104 ), at least one of said locking pins in said single row being a short pin ( 205 a , 205 b , 205 c ) comprising a first, relatively short key sensing part ( 207 ) cooperating with said first code pattern ( 103 ), and at least another one of said locking pins in said single row being a long pin ( 205 f , 205 g , 205 h ) comprising a second, relatively long key sensing part ( 210 , 207 , 208 ) cooperating with said second code pattern ( 104 ).
