Hello XXXXXX,
Pursuant to Texas law, the owner may lock you out if you've failed to pay any part of your rent (Section 93.002). The landlord must place a written notice on the front door stating the name and the address or telephone number of the individual or company from which the new key may be obtained. The new key is required to be provided only during the tenant's regular business hours and only if the tenant pays the delinquent rent.
Your landlord does not have the right to keep your property unless you signed an agreement that the property would act as collateral in the event you defaulted on rent. You should write a letter to the landlord claiming the property and telling him you would like a date and time that you can come get it.
