Yes, there is a well-known account in Jain tradition involving the "locking" (i.e., closing off or restricting access) of the Shankheshwar Parshwanath idol (murti) at the famous Shankheshwar Tirth in Gujarat.

According to Jain historical narratives, during periods of political instability, local rulers or "Thakurs" (chieftains) sometimes took control of Jain temples for various reasons—protection, political motives, or even personal gain. One popular tradition recounts that a Thakur once locked the doors of the Shankheshwar Parshwanath temple, preventing Jains from performing darshan and worship.

The Jain community, deeply devoted to Shankheshwar Parshwanath, prayed earnestly for the restoration of access. It is said that miraculous events occurred, leading the Thakur to realize his mistake. Eventually, he unlocked the doors and restored the temple to the Jain community. Such stories emphasize the power of faith and the sanctity of Jain tirthas (pilgrimage sites).

These accounts are preserved in local Jain oral histories and temple chronicles. The exact details may vary, but the central theme is the devotion of the Jain community and the revered status of Shankheshwar Parshwanath.

If you are interested in more specific details or scriptural references, you may find them in Jain tirtha-mala texts or local Jain community records.
