Hi i get lock out my macbook and it it not accepting my password

I understand your Mac is not accepting your login password. Is that correct?

If so please check that your MacBook's Caps Lock key green LED is not illuminated. Even if it is not, press it (once) to toggle its state, then try entering your password again. It is possible for the Caps Lock LED to be extinguished even if it is "on". Press it once and try again.

If that does not work, If you forgot your Mac login password - Apple Support describes the applicable steps. If you can't reset your Mac login password describes what to do next. Follow them all the way through to their conclusion.
