Does the battery power the locking function or just the lighting function?

You need power to engage the locking/unlocking deadbolt knob. Without the battery, you have to use the key.

You have a turn key to lock and un-lock the door. the battery is for the light and the keypad itself.

locking and unlocking are done by manually turning the lever. The battery is needed to engage or disengage the mechanism that allows the lever to lock or unlock.

As has been stated, the battery engages the knob, allowing you to manually retract or extend the bolt. This probably greatly extends the life of the battery, by letting the user do the work of moving the bolt. When the battery gets low, you'll be warned by a a delay before unlock, a High/Low beep then 1 Red then Green light flash. Once it's dead the keypad will not function. The key will always work.

The battery power DOES NOT retract or extend the deadbolt. That is done manually. The battery powers the light and the keypad + mechanism that allows you to engage or disengage the deadbolt.

As far as I know battery power is needed to unlock. So may want to change he battery periodically, say once a year, not when it fails ( or you may still carry a real key). I haven't replaced the battery yet. We love this lock. Also, you should be ale to locate the manual online.

Both, when you press the keys, the they light up. I have had mine for 3 years now and just bought one for my daughters new house. I love this, you'll never lock yourself out. There is also a key if you need it, but the unit lets you know when to change the battery, it does last a long time though. I hope this helps!

I keep mine in the "AUTO" position. When in the holder during daylight hours it remains off, in the dark the "Night Lite" stays on unless there is a light on in the room. At any time, day or night if I grab it out of the holder the light is a constant "ON". When in hand I will turn the control to on or off depending on what I need. When it goes back in the holder I put it back to "AUTO". This question got me wondering so I went around the house and checked them all, they are all working properly. I don't see a way to replace the battery, I'll look into that.

There's an optional magnet that can be installed on the door frame. If you choose to use it, the lock will detect when the door is closed and can be set to auto-lock. Yes, it uses batteries.

Yes, it just uses normal AAA batteries. Very good lock. I have been using it for about a year and it works just fine!

Not sure about the battery, but it does measure FC and Lux with a flip of a switch.

Dont remember but I got the battery out of home Depot. Sometimes the buttons get stuck so watch the light.

It not only powers the keyless function, but the battery also lights up the buttons if you try to operate it in pitch-dark. If you remove the battery, the lights will not light up, the keypad will not function, and you will not be able to use it for the intended purpose...AS A KEYLESS LOCK. Leave the battery in, JP.

Neither. When the batteries are placed inside, the lights go on. Then after awhile, they will turn off. When you put the light in a dark place, they are supposed to activate, but it fails to do that. It does not turn on in either the day or the night.

i'm not exactly sure... but I think the lock switch disables all functions to avoid pocket unintended turn ons.

The battery requires a "cage mount" that has two electrical contacts on the bottom that match up to two contacts on the bottom of the battery.It also requires an locking pin that locks the battery in the cage and holds it firm against the bottom contact points. The locking pin on mine uses a key to operate it. Hope this helps.

When using battery power the backlight stays on for 2 minutes. When using AC power the light stays on continuously. (Unless you turn it off).

On mine it is a ring that turns one way focuses the beam the other way spreads. Don't know that it actually locks but has click turns..works well..have to say I love this light! Very bright!

The headlamp has a lockout function. Press & hold the button to turn it on until the light on the side flashes. It is then locked.

This is great little light for unlocking my front door. The light is steady only while the button is held down. It's either off or on. It doesn't flash.

I think the answer is that it doesn't. You can lock it so that the pushbuttons don't activate any of the functions, but there is no on/off button and I don't think it ever powers off automatically. The good news is that it is a low power display and is probably similar to a wristwatch in power consumption. Some people actually pop out the two AAA batteries if they plan to store it for a long time.

Correct. The backlight is on as long as the device is getting volts. The internal battery is just an LR44 button cell that keeps the time and temperature functions running.
