How, specifically, is one easier to bypass than the other?
Everyone knows 2.4 is easy to exploit. Check to see if the lock has a specific additional radio frequency listed (usually in the 900 mhz range) 2.4 I can jam when u think it worked. 900 mhz, usually 915 mhz is used in addition for secondary confirmation of connectivity.
Any whew, for Joe Customer, fyi, the locks with digikey although higher priced, are ok. Locks that connect with "Ring", hehehe doorbells,cameras, etc will offer automated unlock functions as well as proximity unlock ( phone gets close and auto unlocks so no app on the phone timeburn) Google nest will not unlock like this. This seems to be an important convenience to me. They just dont "mention" it, THEN you figure it doesn't.
The latest Schlage fullset lock is o.k. More like slapped the smarts on existing.locks. But gives most features folks want.
Most all residential locks will be 2.4, just insure you dont skip security setup on the app. Many people will "get back to it" and never do.
