A Wyoming tenant may be allowed to change their own locks because the state’s laws do not explicitly forbid it. However, an individual lease may still prohibit this kind of modification. As such, a Wyoming tenant should always seek written permission from their landlord before beginning the process of changing their own locks. For best results, this written permission should also establish how soon their landlord will receive a new copy of their key.
