Boxster Immobilizer Module- under seat

[njtech]

I was lucky enough to leave my window open during a
big storm and found a pool in my 2000 Boxster S. So the module
under the seat was submersed and clearly blown out.
:ah:

I took it apart and used compressed air to get all the water
out but unfortunately it doesn't work. (fuse didn't blow)

So my question is can I get a used one and have the keys re-programmed?

I can't find these modules anywhere via Google..

the part# on the box is 996.618.260.07 also
