Good tips on the lithium batteries—I learned that one the hard way too. Another thing I found helpful was insulating the battery compartment a bit. I cut a small piece of foam weatherstripping and placed it around the battery housing inside the lock. Seems to keep things warmer and running smoother in freezing temps. Still, like you said, nothing beats having an old-school backup key stashed somewhere...just in case.
Good call on the foam insulation—I did something similar after a client had issues with their keypad lock freezing up. They called me in a panic because they were locked out during a cold snap. Turned out the battery was fine, but the electronics just didn't like the freezing temps. I ended up using a thin piece of reflective insulation tape (the kind you use on HVAC ductwork) inside the lock housing. It seemed to reflect enough warmth back to keep things running smoothly, and they've had no issues since.
But yeah, totally agree on having a backup key stashed somewhere. Tech is great until it's suddenly not... learned that lesson myself when my own keypad decided to glitch out at midnight after a long day at work. Standing there in the dark, fumbling for a hidden spare key wasn't exactly my idea of fun, but it sure beat sleeping in my truck.

Haha, been there myself... Ever had trouble with moisture buildup inside the keypad housing? My old house seems to attract condensation like crazy—wondering if your insulation trick might help with that too.
I've dealt with similar moisture issues in my keypad housing too. Older homes, especially historic ones like mine, tend to have quirky humidity and airflow issues that modern tech doesn't always anticipate. I tried sealing the keypad housing at first, but that just trapped moisture inside and made things worse. Eventually, I drilled a tiny drainage hole at the bottom edge of the housing—nothing huge, just enough for condensation to escape—and it actually helped a lot.
"wondering if your insulation trick might help with that too."
Insulation could help stabilize temperature swings, reducing condensation overall, but make sure it's breathable or you might end up with more trapped moisture. You might also consider adding a small silica gel packet inside the housing—sounds odd, but it worked surprisingly well for me. Either way, you're definitely not alone dealing with these weird little challenges... old houses keep us on our toes, don't they?
I get why insulation seems like a good fix, but honestly, I'd be cautious about adding anything inside the housing—even silica packets. Those packets absorb moisture at first, sure, but once they're saturated, they can actually make things worse by holding moisture right next to your electronics. I learned this the hard way with an outdoor sensor... ended up corroding faster. Your drainage hole idea sounds smarter long-term, letting moisture escape instead of trapping it inside. Maybe pairing that with better airflow around the keypad would help even more?
