Pella lock

Thanks for reaching out! I'm sorry to say that we would not be able to provide you with a replacement for your existing mortise lock. It appears to have a faceplate that extends the length of the door. Unfortunately, we do none of the mortise locks we carry would be compatible with the door or the compatible handle set.

You may have some luck reaching out to a local Pella dealer to obtain a replacement but I cannot make any guarantees.

Our sincerest apologies that we cannot be of help with your repairs but please feel free to reach out with any other hardware repair projects you might have.
