Yes, long term renters are allowed (and encouraged) to receive a Key Card, which can be applied for here. For clarification, a "long term renter" is any person who rents a residence from another party, for a contractual period of at least 6 months.
If you are a renter who is renting a property for less than 6 months, please contact your landlord or property manager and inquire on using one of their cards.
