I have a 2007 ford focus that was wrecked?

I have a 2007 ford focus that was wrecked and taken to body shop (A )by wrecker from body shop A. I went to get the car and they drove it out on fri night and on sat morn when the body shop (B) that i chose to repair my car went to get the car it would not crank with either key (the key they had to move the car nor the spare key i had at home). The lock light on the instrument panel lights on and off every 2 sec but the car will not even turn over. Body shop (B) thinks body shop (A) did something to the car because they did not get the job (i have no comment). I would appreciate a solution to this problem
