Can you please explain me this?

Sure thing! Congrats on the new RV. The entry locks on RVs are typically similar to those on regular doors, but there might be some variations. Are you asking about the main entry door?

Most RV entry doors have a key lock just like a house door. You insert the key, turn it to unlock, and then turn it the other way to lock. Some RVs also come with electronic keypad locks or key fobs for added convenience. When you're at a campground, it's generally safe to lock up when you leave, just like you would at home. When you're on the road, make sure all doors and windows are securely locked before driving. About locks, well there are a lot of types of locks that can be found, with most popular are keyless entry for rvs. That is all i know
