The cave Wattson, the Mauville City Gym Leader, tells you to venture inside is New Mauville. He wants you to turn off the generator inside New Mauville. It appears to be acting up and causing problems for people in Mauville City. Inside New Mauville are various items and switches that allow you to navigate through New Mauville and reach the generator. There is also wild Pokemon in the power plant like Magnemite, Voltorb (Three fake items are Voltorb), Electrode, and Magneton. To reach New Mauville you must head south of Mauville City and use Surf in the lake located in Route 110. Surf below Cycling Road and you will see a cave entrance. That is New Mauville. To enter the power plant, it requires the Basement Key (Which Wattson gives to you after taking the request). Hope this helps.
After a certain point in the game, you will see Watson standing in the middle of Mauville outside of his gym. If you talk to him and agree to help him with his problem, he will give you the key to New Mauville.
1st of all it's just like emerald you get 5 badges and go to mauvill and outside will be wattson and he will give you the key and WALA go get to go on a vacation to N_E_W M_A_U_V_I_L_L!!!!!!!!! =D
In Pokemon Sapphire when the player defeats Gym Leader Norman in Petalburg City, Wattson, the Gym Leader of Mauville City can be found at the intersection of Route 110 and Route 118. Upon talking to him, he will give the player the Basement Key to access New Mauville City.
Go south until you are below and out of Mauville City, and Surf in the water until you find a cave: That;s New Mauville.
Watson gives it to you
To get to new mauville
say thank you
You get it from the gym leader. After you beat Norman(Petalburg Gym leader) and get surf, go to Mauville and the gym leader will be standing in the middle. He will give you the key. Then go down near the cycling road and surf. Then go right and you will see a cave.
In Pokemon Emerald, New Mauville is south of Mauville City. Go to the first Fisherman you see when heading south from Mauville City. Surf on the body of water that he is facing, then turn left. As you keep Surfing east, you will find a cave. If you have a Key from the Gym Leader, Wattson, enter the cave, open the lock, and do your mission for a reward from the Gym Leader!

Go to the place where the order is in. Talk to the guy with pimples on his face. He gives you the key. That is how to get the key for astro knights on poptropica.
