Electrical Door lock actuator question..

I'm going to do the @jrichker door lock actuator mod. I've had numerous sets of the junk actuators but i can't remember this one thing. If i go ahead and take the frozen actuators out now, will my doors still lock with the key and the push thingy? I seem to remember having them out once and everytime i close the door it unlocked itself. Anyway..... Can anybody advise?
Thanks!
