Stuck on factory reset due to a keyboard malfunction

I had forgotten the password on my RCA cambio 2-n-1 and proceeded to begin a factory data reset on the device … as it reached a hundred percent and came up the screen that says RCA on it with the option of pressing esp or delete to continue the reset ect… so I attach my keyboard and and my keyboard wont work nothing happened …. My question is how do I continue my reset without a keyboard to press the buttons to continue the reset … also I have no volume or home buttons just a power button
