Rekeying the 300SD and 400SD

These locks do not need to be removed from the cabinet to be rekeyed.

1. Open the lock (the cylinder projects forward).
2. Find the "speed release" button on the left side of the projected cylinder and press it with a sharp tool. The cylinder will spring forward.
3. Turn the key 1/4 turn and pull the cylinder forward out of the lock.
4. Pull up the retaining pin at the rear of the cylinder. Rekey the cylinder either with a follow tool to remove the plug, or through the top slide.
5. After keying, hold the bolt steady and reinsert the cylinder while pressing the speed release. The cylinder realigns itself and snaps back into place.

Olympus Lock sells replacement keys and keeps custom keying records on file for adding locks later.
