figuring out deadlocks

hi,
So this one installation is getting a lot of deadlocks. Most of them are on Reservation Entry. I can catch them with Profiler, but the graph shows somethings strange, both SPIDs requesting exact same KEY. How can I figure out the lock order of previously locked tables? Half of the queries are called through WebService, so the SPIDs always change, and I can't run Client Monitor on that.
I've attached a sample graph.

Unoptimized key can cause big locking problems, especially for versions early than Nav 4.0 SP3.
Nav, T-SQL.
i'm not talking about long blocking, i'm talking about deadlocks..
