I have yet to see an electronic lock designed for residential use (or for single-use without the need for a big system behind it) that was any good.
All of them fail either because the electronics are crap or (more usually) because they have a backup key (and its usually of the kind that's trivial to defeat rather than the kind that's deflatable only with a lot of effort)
Same with pretty much all the safes you can buy at hardware and office stores, most of the ones I have seen either have key locking mechanisms that look somewhat beefy but are probably not that secure in the real world or they have electronic keypads with backup key locks (usually trivially picked tubular locks)
Why are so few people making residential locks with genuinely GOOD security?
