Eneloops would only last about 3 weeks. And disposable last 2 months. This door is used a lot and since it has Zwave and a door open sensor it sends info on every open.

Bonus, since it can handle the lipo AA batteries that put out 1.8v and it gives the motor more oomph I made the battery pack give 7.2v and it never sticks anymore.

This is a garage-door so its not critical access but is used a lot.

imagine having a door/lock that requires power..

Imagine being locked out of your house because you forgot to bring keys with you.

Like, I'm sorry if you disagree with this, but holy shit, having electric locks on your doors where you can get into your house based off a fingerprint or a code is a fucking game changer.

I have two on my doors, one on the front, one on the back, and I installed them at a week or two apart, so if one of them starts complaining that the battery is low, the other one's still good. If one of them goes dead while I'm on vacation, the other one's good.

Not to mention that you can unlock the door from your phone in case somebody comes over unexpectedly, or if you have a friend coming in from out of town and you're going to be at work when they arrive, you can create a code for them to unlock your front door and come in while you're not even there.

Plus they still have key locks that I can use if the batteries are completely dead and they can be powered by a 9 volt battery in case I don't have the key with me.

They're freaking awesome and I am glad they exist.

Yeah and it makes it pathetically easy to break into your house. Just search online for some of these “security locks using fingerprints”. Its even easier to break into sometimes than a regular shitty lock.

You can't lock yourself out of the house with a deadbolt, they require the key to lock

You can also leave without a key and then your roommate also leaves and locks the door.

[–] SchmidtGenetics@lemmy.world 4 points 1 hour ago

But you can lock the handle and leave without keys.

You can leave the handle unlocked, and just use the deadbolt this way.

Imagine not having a lockpick kit on you to just let yourself in

Imagine having keys so you can let yourself in when you forget your lockpick kit.

[–] Brkdncr@lemmy.world 9 points 2 hours ago

I have a similar one and can still use a key…

[–] NOT_RICK@lemmy.world 16 points 3 hours ago (1 children)

It’s pretty convenient actually

I dunno what’s wrong with their lock, but I use eneloops on my lock and I swap the batteries probably 2-3 times a year

[–] TragicNotCute@lemmy.world 5 points 2 hours ago

It’s the best. We have auto locking deadbolts that lock themselves after a period of time. Each family member has their own code to get in and it has a normal key hole if you want.

[–] SchmidtGenetics@lemmy.world 8 points 2 hours ago* (last edited 2 hours ago)

I can head out for a walk without bringing my keys with me. Kids can open the door while I’m grabbing the groceries or other stuff. Can provide a temporary code for someone to check on it while I’m out. Family can have a code for emergencies, or if they need to watch the kids.

It’s hella convenient actually.

Yea, it is nice being able to check if you locked the door from bed. Definition of luxury, but I didn't buy this one it was a gift.

[–] DonutsRMeh@lemmy.world 3 points 1 hour ago

Ok, you get a pass from my “or just use a damn normal lock” dad’s finger wagging 😂

[–] artyom@piefed.social 1 points 1 hour ago

I use one because I often forget to lock it and someone walked into my home while I was in bed one night.

[–] kibblebits@quokk.au 4 points 3 hours ago

Sounds amazing. I’ll know if I didn’t lock the door.
