Hello and welcome. I am very sorry to hear about this understandably frustrating experience.
There is nothing inherently illegal about giving the impression a job is going to be classified as a W2 "employee" position and then instead making it a 1099 contractor position. Even if this were a violation of some law, the damage arising from this misrepresentation would be so minimal (essentially, it's the different of withholding taxes) that it would not be worth pursuing a lawsuit over.
That said, not just anyone can be a 1099 contractor--it's not up to the employer to decide based on convenience or the employee's schedule. A workers can only properly be classified as a contractor if they retain significant control over how and when they perform their work.

Based on the nature of the job you describe, it is likely that the position MUST be classified as W2 employee.
This issue aside, they must pay you your earned wages
regardless of whether you continue to work there. If you can argue that you are an employee, then your employer must pay you your earned wages the earlier of the next scheduled payday or 7 days from the last day you work. If you are a contractor, though, there is no deadline other than that which would be imposed by your employment contract
, and your sole remedy would be to file a lawsuit to collect what you are owed.
Unfortunately, you cannot legally keep company property to leverage getting paid. In theory, they could sue you for the replacement value of the key. Who knows what other allegations of trespass of theft they might also conjure up. It's not a road worth going down.
Ultimately, if you are not paid, the best course of action would be to file a wage claim with the NV Labor
Commissioner. the Labor Commissioner will determine whether you are an employee and issue an order requiring your employer to pay you what you're owed. Filing a wage claim is a free administrative process that does not require an attorney. See here for more information: http://nevadalawhelp.org/es/resource/wage-claims?ref=8oFcz
