Tenant broke the key and now wants me to replace the lock or key

[Nadia Hale]

Hello, so my tenant has bent the key while trying the lock . They say it is unusable at this time . Is it my responsibility as landlord to replace this key if possible ? I don’t even know if it’s possible to do so .

Also, if not possible I am sure she will ask to change the lock 

pleade advise . This is a very difficult tenant who is always unreasonable  with thier requests .

Thanks

Unfortunately that’s the only key and now that’s it’s bent ( not broken), can they even make a copy ? Or does it come down to changing the locks as no one can duplicate the only bent key? 
thanks so much !! 

 So my first question is "Why is that the only key?" Makes no sense from a landlord point of view. Don't you keep a master key for the locks, and if not, why not? 

Assuming they broke the key in the lock, you should replace the lock. If the lock was hard to turn it's not hard to snap one as @Scott Mac noted above. And keep extra keys.
