Locksmithing/dissable anti-lockout old Schlage privacy


I'm trying to lock my bedroom door even when I'm outside of it. I have young grand kids and bedroom is not child safe. Depressing the latch unlocks the lock, so I can't push the button and close the door to lock it. The lock is a Schlage, from the early 50's. The only numbers I found on the lock were M45. Any hope.

Hello Scott,

Privacy locks are designed to unlock when the door is shut to prevent lockouts, well most are as it depends on the brand.  Yours is one of those.

It cannot be modified to use how you need it although if the emergency access hole allows for a screwdriver type of tool you might be able to shut the door then lock it with your emergency tool.  I'd think not though since you stated you have to depress the lock button from the inside.

You'll have to get a keyed lock for this door to lock it when needed.

Most locksmiths will have that lock on the shelf for you to pick up.  You should note that due to the age of your lock, it may have been installed in a hole smaller than newer locks will fit into so you will have to modify the door a bit for a new lock.

I do not answer Safe or automotive questions. Period. I am knowledgeable in almost every area of Locksmithing. This includes locks, keys, lost keys, residential and commercial lockouts, rekeying, masterkeying, high security locks, access control, electric locks, security cameras and home safety. I have been running an online business since 2004 where I sell all types of lock and security hardware to everyone from apartment renters to business owners to the US government. Before that I started a locksmith service in 1999. I deal with many types of security equipment including high security safe locks, heavy duty padlocks, exit devices, biometric readers, electric strikes, magnetic locks, full surface hinges and I only sell what I personally stand behind 100%. The online business has given me a more in-depth look at the locksmithing industry, helping me to learn more about each and every product that I offer, as well as products I don't have but end up finding for customers to solve any issues they have with security or door hardware.

Please don't submit any automotive or safe questions as these aren't areas that I can help in.
