ABLOY Classic ABLOY Classic ABLOY Classic The unique ABLOY lock and key was invented in 1907 by Emil Hendriksson an office machinery mechanic in Helsinki, Finland. While repairing a cash register, he realised that the rotating cylindrical discs of the machine were eminently suitable for use as a lock mechanism. We now know this locking technology as the rotating detainer disc system and the keying platform as ABLOY CLASSIC. Renowned for it's reliability, strength and master keying capabilities it became the benchmark for keying platforms world wide. The ABLOY CLASSIC platform is still manufactured today and is the right choice for locking products on an unrestricted keying platform.
