These aren't secrets, but may not be well known (unless you watch LPL):

Sentry Safes aren't safes, they are fire boxes with a fancy lock.

High security locks are not high security because of the lock design, but because the keys are very difficult to have duplicated.

No one (except maybe intelligence agencies) breaks in to a house by picking a lock, especially in the US. Windows, weak door frames, and, in a pinch, making a hole in the wall are all faster ways of getting in.

Car keys are so expensive because many manufacturers charge a subscription or per-use fee to access and program the keys to the ignition. These costs are passed on to consumers

No one is picking your locks just to move things around or steal small, insignificant items. You are either suffering from a mental disorder or a trusted member of the household is gaslighting you (it's not gaslighting though, ~~you're~~ your grasp of reality is slipping. Don't call me for a pick proof lock, just get help please)

Some manufacturers (you know, in China) will put any sticker you want on the products they produce, including UL and ANSI stickers. Before buying a product that is supposedly fire-rated, such as a fire safe, check the UL website to verify the item is actually listed with them.

"Grade 1" door hardware sold in stores like Lowe's or Home Depot is, at best, Grade 2, and is likely Grade 3 (residential grade). These grades are really just about how durable the product is over time, and how much abuse they will endure by the public.

And just a little practical advice. Find a qualified, honest locksmith before you need one. We're like plumbers. If you wait until you have an emergency to find one, the quality will be questionable. There are a lot of scammers out there. If you don't have a resource for locksmiths beyond Google, look on the ALOA website for members in your area. The good ones will know who the other good ones are, and won't be shy about sharing that info if they are unavailable or too far away
