Need to replace a standard rim cylinder, however the nightlatch has a double locking key hole on the interior deadlock leaver.
If I replace the rim cylinder, will the rear lock accept any standard yale key? The keyhole on the nightlatch rear does not seem to have an actual cylinder/locking mechanism within it. Are these just fake keyholes that just engage the main rim cylinder from the other side and lock the handle in place?
What I am getting at...can I just replace the rim cylinder without replacing they keyed nightlatch?
