The Keitaizer (ケイタイザー Keitaizā) is a flip cellular phone device that MegaSilver used to transform. To transform, he pressed a button on the side to open the flip covers, then he pressed 2 (M) + 5 (E) + 8 (G) + 0 (A) and pressed the arrow button which meant 'Enter'. Red letters flashed 'Mega' on the round screen. It uses many of the same features as the Digitizer (but with MegaSilver's own unique vehicles) and is also used as an actual cell-phone. The device's name is actually a play off of "Keitai Denwa", or "cellular phone".
