Replacing Door Handle with Door Handle and Key/Lock

The door handle has a lock on it but only from the inside.
I would be looking to add a key lock if possible to existing door handle.
Otherwise, a door handle with a lock and key that can be locked/unlocked from inside and outside.



Hello, thank you for posting!
Unfortunately we are not able to cross reference the brand of the door. To move forward, we will need to see the original interior and exterior handle with the internal mortise lock. Please let me know if you have any questions.




Thank you for the additional photos.
A new handle will be needed to obtain keyed access. Please take a look at our 82-030 handle set that is compatible with the 82-310 key lock, which would need to be installed for keyed access. You will need to compare the dimensions to confirm that your current installation holes are 3-15/16". Please also review the video guide below regarding how to install a key lock cylinder.
