Question Can't login to Facebook on tablet

[Gipsybee]

I'm logged on on 2phones and laptop but cannot login on tablet as its a new device. Tried security checks, security code and nothing, just stuck in an endless loop of the account is locked. It should not be so difficult to login to an account on another device!! Any idea how to prevent 'security' from blocking me from my account on my device? Have unlocked the account from laptop, have entered number sent to email, tried even changing password. Nothing works!

Is it new as in brand new right out of the box or new to you?
