I recently moved into a property that has a door provides direct access to the garage. However, the landlord told me that he lost the keys on the day he handed over the keys. Unlike the front door lock, the lock on the garage door itself seems weak, and this makes me feel insecure about the safety of the property.
Is it reasonable to expect the landlord to take the responsibility to have it replaced?
Yes, ask the landlord to replace the lock to one or both of those doors and give you keys. If you are worried, get permission to fix an internal bolt to the connecting door so that it can’t be opened from the garage.
