Looking for some recommendations on a RFID lock for a cabinet door and drawer. It must fail open. I’d like for it to have a battery option but I will have access to a power source.
All the options I've found are made in China, there are US based resellers (e.g. Lock Connection) who warehouse stateside and test the products they ship.

I prefer the type where the door-side latching piece looks like this (pins on either side of the mushroom latching piece are spring loaded). Generally these are designed such that if the battery is nearly dead, they will not re-latch (once opened) until you swap in fresh batteries.
If you get locks with an external power jack, you can hide the power input where it's accessible from outside, and if the battery goes completely dead, applying external power will allow you to use a programmed card to open the lock.
There are a few brands (e.g. Wooch) which truly "fail open" (or can be set to this mode), if the battery drops too low for the card reader to work, "auto-unlock" kicks in and it fails insecurely.
