Hmmm… The room it will be protecting is absolutely heated, but given the transmission of cold through steel (albeit insulated steel) I may run into an issue. Plus, as @jensed pointed out the weather may get the best of the lock much quicker.
If the locks were cheap, that’d be one thing… But they’re not. They’re $150 on the low end, and I can get a substantial – and reliable – traditional lock for $50.
I guess I’m not sold, and I’ll just have to suck it up and look like a janitor carrying a few more keys for another couple years while they perfect the technology. Again, the last thing I want is a buggy door that could fail on me.
