Use the correct key
Check whether the door is already unlocked
Turn the handle or knob while pushing or pulling the door
Use the interior thumb turn if it is a privacy lock
Enter the access code if it is a keypad lock
Use a card or fob if it is an electronic lock
Contact the property owner, manager, or front desk for access
Call a locksmith if you are authorized and cannot unlock it
Use the emergency release only if you are inside and it is designed for that purpose
