Disassembly instructions
The Schlage Primus is disassembled in the same way as a traditional pin-tumbler cylinder. Care is taken to account for the sidebar and finger pins. Finger pins are spring biased outwards when the plug is exposed without a key inserted.
- Remove the cam or C-clip.
- Insert the key and turn the plug 45-90 degrees.
- Withdraw the plug from the cylinder. (A plug follower is recommended)
OR
- Remove the chamber casings and take out each pin-stack individually
- Remove the cam or C-clip.
- Withdraw the plug from the cylinder.
Vulnerabilities
Notes
- Key bumping is possible only with a bump key that has the correct sidebar code.
