I don't really agree. I hoped to share my thoughts so I hope no one takes offense, it's my first time posting on the forums.
The only way a player could get stuck outside their own building is if that player dropped their key in some far place, died far away, or lost it to another player. There should be risks and consequences for venturing far from your own home to explore a place that might cause your death and not just by players but also the environment. It adds excitement and a sense of accomplishment for success, highlighting on and bringing to the forefront the survival aspect of the game. The idea that players would rather explore carefree by leaving their items at a base, die, and waltz back in the home, doesn't seem enjoyable, just routine.
Why would a player intentionally place their key within their own structures and then put up a wall? Unless there is a strategy to this, such a player would have to be careless or masochistic to do so. With the implementation of wall upgrades and other new fortifying features to come in the future, why would anyone need to construct such large or elaborate buildings that require layers of doors and walls inside one's home? Isn't it a flaw in Legacy Rust that buildings were so insecure it needed to be built in such over-elaborate and time consuming ways? That tells me it needed to be changed.
In addition, we don't even know if they're implement other methods to gaining access to bases yet. The keys might add personalized tags to name, label and match your doors. They might upgrade the locks into more advanced systems in a series of tiers, as explained in the devblog, from simple wood barricades, basic locks, and finally advanced number pad systems.
I think it's way too premature for making such decisions because players aren't used to these changes in game play. I rather focus on improving functional aspects of the game instead of removing valuable features and concepts that adds a new layer to game play politics and planning entirely, where as before was a mere afterthought.
If your building was recently robbed because you decided to log out of the game for a night, then I would suggest to the developers that walls need to be adjusted to last longer for offline players. That way we don't have to return too frequently.
I agree that wall jumping needs to be changed, no one should hop on a roof so easily.
I agree that there needs to be a sense of danger and risk when venturing out. But doesnt the PVP element sort that already? No need to complicate it even further by giving someone the keys to the house you just spent hours building
People enjoy being creative and building large and extravagant houses. When you are capable of building cool big structures it seems stupid to then deter people from doing just that by having a crappy key system. And yes I suppose we dont know which direction they're going with it. Just wanted to voice my opinion that its not good at the moment
I think being able to destroy walls/anything with just melee weapons is dumb. You could get a gang of 5+ people and break into every house without even setting up your own base first or gathering resources for C4 etc
