Maybe I am misunderstanding you, but no the commandments of Christ do not save.
There is no law that is capable of saving (only convicting/condeming), only what Christ has done on the cross saves us.
Once we turn to Christ and are born again, then we die to the power of the law (sin which results in death) and are given a new heart of obedience. Obedience does not save, but we are obedient because we love Christ.
Those who are not obedient to Christ are not born again and do not love Christ. Those in Christ do not continue in sin or willfully break His commandments, by this we know who belongs to Him.
