After adding TACACS statements, I get 'authenticaion failed' on console

Adding TACACS on a new router, already have an existing TACACS environment. I add the TACACS statements, quit the console session I get the 'press return to get started' message. I press return and the screen rolls up and displays again 'press return to get started'. When I scroll up, I see 'authentication failed' when i've entered nothing.... Don't know why.

You may have locked the console /login access accidentaly..Try to telnet to the router and see if that works..Otherwise, you need to do password recovery located at

and after that start entering those commands again carefully..Thx..Tejal

Thanks for the response but I just found the problem. I looked at the AAA server and saw that I had a key mismatch. Even though the keys entered on the router and the aaa server, there was some unprintable character or something going on. Anyway, all is well and thanks again.
