If the pokewalker gets wet I will try and take the battery out and dry it as much as i can, I am not that positive it will still work but hopefully it will.
When the screen says, "This Pokewalker has already been registered" or something similar, it means that Pokewalker has been registered to a different game card. In order to send your Pokemon on a stroll with that Pokewalker, follow the instructions below. On the menu screen, select "Connect to Pokewalker". This will take you to the Pokewalker menu. On this screen, hold the DOWN button, the X button, and the L button. This will give you a warning to reset everything on the Pokewalker. Select Yes, and follow the instructions given to reset all the data on the Pokewalker. This will not delete your Routes, however. Afterwards, follow the on screen directions to register your Pokewalker again. This will allow you to send Pokemon on a stroll in the Pokewalker again. If your Pokewalker gets broken or lost with a Pokemon on a stroll, on the Pokewalker menu, hold the UP button, the SELECT button, and the R button to force your Pokemon back into it's PC Box in the HeartGold or SoulSilver game. Take note you will not receive the items and Pokemon you found.
By unlocking the pokewalker route
yes
You can't put a Pokemon in the pokewalker in Pokemon platinum, as the pokewalker was designed for only Pokemon Heartgold & Soulsilver.
