    I wish you stated make model year.

    Locked as in, the car is in gear and won't roll?

    Or is the pedal REALLY HARD to push?

    If it won't rolls when in 'D' it is a mechanical, meaning a linkage is apart or impeded or the new booster is bad.

    Hard to push means a vacuum line was left off or a one way valve in the booster where the vacuum hose connects is bad.

    Most cars you can see the booster.

    There should be a black hose about the size of your thumb that runs from the engine or a junction of hoses to the booster. You could check to see if the hose is there.

    Remove and plug the vacuum line running to the brake booster and drive without power brakes to see if they still lock up. You wither have a bad booster or you don't have the adjustment correct for the master cylinder.

    Bleed the brake lines...meaning you need a second body.
