i have a newish plastic front door with a Yale lock with eurocylinder. it has an annoying feature but maybe there is a reason for it. can aonyone explain please?
The eurocylinder has two cylinders for the key, one facing inside and once facing outside. You can unlock the doo from either side, but it latches simply by being closed.
the trsange featiure is this: If you leave a key in the inside cylinder then this seems to prevent you fully inserting a key into the outside cylinder. So, if you do leave the inner key in place then you can lock yourself out even though you have a key.
Is there a reason for this feature?
