わけがない flatly rules something out: 彼がうそをつくわけがない, "there's no way he'd lie". There's no reason or logic that could make it true.

It's very close to はずがない (N4). わけがない is a little more common in conversation and more emotional; はずがない leans on expectations. In casual speech, が often drops: わけない.

The polite form is わけがありません.

Watch out for its lookalikes: わけではない is "it's not that…" (a partial denial), and わけにはいかない is "I can't, given the situation". Only わけがない means "no way".
