With pure luck

Mrs. Incredible feels around with her hand feels something leathery and then moves her hand up and feels something soft, after a second touch, she knows she is touching the guard's face.

She then puts her hand in a fist and punch the man and feels his body and finds his keycard.

While she is doing that, she stretches her leg and kicks the other man behind her in the face. The other guard with him, laughs until he too gets kick in the face.

She then uses the keycard and slides it into the elevator door slot, opening the doors.

The **** of her coming back together knocks the two guards out.

Mrs. Incredible puts her shirt down and looks at the unconscience guards.

She could go into the elevator or she could have some fun with these men who dare touched her.
