Q: how can i unlock my apple ID without password and security question?

You need Apple's help to unlock it, if you neither know the password nor the answers to the security questions.

If you still know your AppleID password you can proceed like described here:   If you forgot the answers to your Apple ID security questions - Apple Support

But without the password give the Apple Account security team a call.  The contact information for the different countries is here:   Contact Apple for help with Apple ID account security - Apple Support
