Can't entirely give you an exact answer as I'm not privey to your condo docs, however this is how my previous condo worked.
1. The board had no right to ask for keys to any units (for security measures).
2. If a locksmith is needed for any reason, the cost is 100% paid by the unit owner.
3. Any emergency repair costs are 100% paid by the unit owner.
4. Unit owner is responsible for any piping after the main unit shut off valve.
5. Any damages from piping after the main valve, either to the owned unit or other units surrounding/below as a result of the leak is paid by the unit owner that had the leak (or unit insurance).
Is there any evidence at all of a leak in your unit? Blistering drywall? Swelling flooring?
