Principles of operation

The ABUS E50 utilizes a key that is bitted on the narrow side of the blade and is one-sided. The lock uses five chambers for pin-tumbler stacks. Each of those chambers contains a set of key pin, driver, and spring. Four of the driver pins are spooled security pins. To open the lock, all five key pins must be aligned at the shear line.

Disassembly instructions

The use of a pinning shoe is the preferred method for disassembling a double Euro profile cylinder. Another method is to use a segmented follower. The c-clips retaining both cores must first be removed and then both cores can be pulled out slightly in order to remove the center cam. One core should be rotated to approximately 4:30 or 7:30 o'clock position -- 135 degrees either clockwise or counter-clockwise -- once the cam is removed. This allows the core to be removed without driver pins entering gaps for the cam clutch. At that point, a segmented follower can be used to remove the core.

Locks not intended for installation and use can be disassembled in a quick but destructive procedure. The cylinder housing itself can be cut in the middle using a hacksaw or grinder. The cam will no longer be held in place and can be removed. The resulting two cut half euro cylinders can then be disassembled as outlined above.
