There are a lot of zwave s2 locks out there. No Bluetooth at all.

128-bit AES isn't amazing, but it's more solid than bluetooth and most hardware locks.

Most locks, including deadbolts, can be picked or bumped in seconds. The physical lock is the weakest point. You can get zwave s2 smart locks with just pin pads, no physical key. That's probably the most secure option.

Silicon Labs Z-Wave chipsets contain multiple vulnerabilities

CVE-2020-9060 Z-Wave devices based on Silicon Labs 500 series chipsets using S2 are susceptible to denial of service and resource exhaustion via malformed SECURITY NONCE GET, SECURITY NONCE GET 2, NO OPERATION, or NIF REQUEST messages.

Oof. Could you imagine having a vindictive neighbor who is mad at you over some dumb shit you have no idea about, then then DoS’ing your lock that has no physical key?

Again probably as close to zero as a non zero chance can be of actually happening, but idk just give me a key and some buttons for when I have bags and shit.

Also, if i decided to go in to home invasions I’d rather just carry around a phone or a raspberry pi or something and pop smart locks than carry around a snap gun.

Everything you’re saying is right though, there’s always a trade off when it comes to security.

Lock picking takes skill. I've defeated a deadbolt and doorknob with a cordless drill in ~15 seconds. And it's not even all that loud.
