Can I start my Prius 2007 with only the matal key?

I think what matters is, is the PCB on the key fob still intact? If its intact, even though it's broken, you could still start and drive the car. The only problem you might ha e is the remote key won't be able to operate an d lock/unlock the doors. But you could use the mechanical part of the key to perform those functions.

I think it should be cheap getting another key off eBay, and get it programmed.

In a word, no. Where would you put it? There is no ignition switch.

The good news is, the RFID chip that starts the car does not require power from a battery, it uses induction power from the chip reader, much the same way a Snapper or HOP card (transit cards) works. The RFID chip is sealed, so should not be affected by a soaking in liquid. Just make sure the key FOB is dried out before use, so you don't contaminate the FOB holder receptacle.
