Most privacy locks are easy to get through once you know the secret of that particular lock type. IMHO every renter and homeowner should take the time to familiarize themselves with the locks in their home and how to bypass the privacy locks.

Even if you don't have kids. You never know when kids might visit and, of course, older folks can have difficulties. In one case I'm familiar with an elderly gentleman had a seizure and the fact that someone was able to bypass the privacy lock in seconds saved time and avoided the need to damage the door. As it was it also avoided injuring him because his head was in the swing of the door.

It is really easy to figure out and practice when your not under pressure and have access to both sides of the door.
