→Troubleshooting 2- Mortise does not mechanically lock

There are 2 possible scenarios as to why the mortise does not mechanically lock (with mechanical key):

1. The key cylinder gear might be misaligned
   • This rarely occurs because the key cylinder and its gear are screwed down by a plate
   • However, if it does occur, unscrewing the plate and realigning the gear will fix the issue
2. The key tail piece was not installed into the doorlock or the key tail piece was cut too short
   • Check if key tail piece was put into the doorlock. Once key tail piece is inserted into the doorlock, the mortise should mechanically lock and unlock using the mechanical keys
   • If key tail piece was cut too short, it prevents the front body (key cylinder) from engaging the mortise
   • Replacing the key tail piece will fix the issue
