How does thomas jefferson use john locke's social contract ideas in the preamble of the declaration?

In the Two Treatises of Government (1689), The French philosopher John Locke claimed that men were by nature free and equal, but with the purpose to interact in a healthy society, they needed to transfer some of their rights to a government in a "Social Contract". Under that contract, the government had to be elected by the people and had to protect people's natural rights to life, liberty, and property, and, whenever the government failed to do so, people had the authority to abolish it and replace it.

These ideas highly influenced the Declaration of Independence, in which the Thirteen American Colonies unanimously declared independence from Britain for its tyrannical rule. The colonists used Locke's ideas in the Preamble of the document to denounce the British crown for violating the social contract:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.--That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, --That whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or to abolish it, and to institute new Government.

americans had many intangible advantages. well since the british fought a war far from home military orders, troops, and supplies sometimes took months to reach their destinations, and the british had an extremely difficult objective. they had to persuade the americans to give up their claims of independence, americans had a grand cause: fighting for their rights, their independence and their liberty. this cause is much more just than waging a war to deny independence.
