Question
my 2005 chevy impala says lock on my radio how can i get it off can enany  one help me

Answer
It is probably an anti-theft lock out.  This is a code that is required in order to activate the radio again and is caused whenever the power is removed from the radio.  You can get the code from a GM dealer or whomever they have designated to give out the codes but you will probably be required to show proof of ownership of the car.

There are some companies claim they can give you the code - for a fee - such as the one below:

You can google for others.

Wishing you success.
