Accessing another stake's building

Our ward is located closely to another building that is not in our stake. In the past we have had access to their calendar so we can schedule days to hold baptisms there. It is the only thing we use it for. Our stake and ward building are about 30 to 40 minutes away depending. This building is less than 10 minutes so people prefer having baptisms here. A few months ago our access disappeared. I have gone to this other stake and asked for access and the didn't know how to help us gain access either. I had our stake clerk also try to help. If you need authorization from either I can provide that. The building is the Silverlake Building in the Friendswood Stake in Houston, TX. I am in the Shadow Creek Ward in the Houston Texas South Stake. Please let me know the best way to solve this issue.

Thank you,

Brock Stringham

Someone with stake admin access in the other stake will have to add you in.
