In SOLIDWORKS, “auto lock” can mean a few different settings, so the fix depends on what is being locked. The most common one is a system/workspace preference that automatically locks objects when they are added, and that can usually be turned off in the admin or system settings.

What to check

  1. Workspace object auto-lock
    • In some SOLIDWORKS-connected workspace/PDM setups, there is a preference like “Automatically lock objects added to workspace”.
    • Change that preference from Yes to No if you do not want new items locked by default.
  1. Locked system options
    • If the setting itself seems locked, an admin may have applied it with a Lock checkbox, which prevents users from changing it.
 * In that case, the option must be unlocked by the administrator first.
  1. If you meant PDM auto logon
    • If you were actually asking about automatic sign-in rather than file locking, that is a different setting entirely and can be disabled in the PDM admin/client login settings.

Where this usually lives

  • System Options / admin-managed settings for SOLIDWORKS configuration.
  • Workspace preferences if you are using a PDM/workspace integration.

Quick example

If your files are getting locked automatically when added to a workspace, look for the preference named Automatically lock objects added to workspace and switch it off.

Extra note

If you meant a different “auto lock” feature, such as a mate lock, sketch relation lock, or drawing-view lock, the steps are different.
