I think I have the 82-400 lock assembly with a failed mechanism. How to remove the old one and install a new one. Thanks.

We'd like to first confirm that your lock set is similar to the 82-400 prior to offering some instruction on how to disassemble it and replace it. Could you upload a photo for us to see? This will help us see what 's currently being used on your door.

Please see attached photos for my lock and advice on type and disassembly.

Thanks.

Thanks for getting back to us! In my experience, you have to first remove the inside and outside handles, and then the mortise lock itself. As long as the handles are installed, the spindle connecting them prevents you from removing the mortise.

I don't think there's any trick to it beyond that. Where exactly are you running into problems?
