If it's hardwired to the opener or interior button, what are the batteries for?

You would think it would just run off the power going to the opener. I assume its for the light that lights up the buttons when you open it up.

It is hard wired to the power source. The key pad goes on the outside of the garage and the inside button goes inside the garage. The batteries are a back up in case the power goes out you can still get in the garage.

The batteries power the keypad unit and it provides a contact closure that connects to the opener.

The batteries power the keypad, which lights up, and sends the signal to the controller

As long as it's wired (not a wireless remote), I believe pretty much any opener should work. It's just the two wires connected to two screws on the back of the remote. Pushing the button simply makes the connection (much like a doorbell button).

It has a reverse polarity prevention relay. If the battery being jumped is completely dead, it won't trip the relay to pass the current from the internal battery. It is a bad design

You may need to remove the opener from the wall to be able to change the batteries.

Good news is that this one is a combination lock. No batteries needed. The SentrySafe that it replaces was electronic and the solenoid died, which meant that a crowbar was needed to open it one last time.

It is wired to the opener. It is wired to the same ports as the reverse sensors. It is very simple and the instructions are easy to follow.

twist/ turn the unit to open for mounting & wiring. There is no internal battery.

If there is an internal battery I don't know how you would access it. As far as I know, there is not one. It doesn't talk about it in the programming instructions.

There's a hole in the housing on one side of the battery, and a door that swings open on the other side. You just push the battery through the door using a paper clip, install the new battery, and close the door.

They provide a couple of keys to manually open the lock. There is also a warning beep to remind you to change the batteries when power gets low.

Inside the unit, under the top part, just under the hand-print. It's a small red button, attached to the battery compartment.

I don't know because it is buttoned up inside a flashlight.It fit inthe location that the old battery came out of. One thing, this battery holds a LONG charge, I like it.

As a novice at electrical things, I really don't know the answer to this about wiring. I just followed the code, ups and downs, inside my old remote which was taken from inside the opener. I do find the range less than the old one, but I would rather be safe and not open the door too soon! Great item for the cost.

To open the battery compartment. The way this baby goes through batteries you are going to use it a lot.

The battery is on the side of the remote. I had to take a pen and push on the button hard and then pull open the slide. underneath on right.

The lock switch disables the buttons on the wall console AND DISABLES ALL GARAGE DOOR REMOTE CONTROLS. Found out the hard way when someone flipped the switch and suddenly the remotes in the cars and the wireless remote outside the garage door no longer worked to open the garage door. But, it is great for vacation security.

The batteries are internal but there is a key that can be stored in another location in case of a dead battery.I would assume if the battery dies it would stay locked and you would have to use the key to open it.
