Keypad burning through batteries

Hi there. Do you see the Keypad lighting up all the time even when there's no one nearby? The proximity sensor does use infrared, so there could be something in the room (that generates heat) that is triggering it.

But other than that, the only other culprit would be extreme interference, which is forcing the Keypad to work harder to maintain the connection with the Base Station. That would also use up a lot more power than usual.

Interference can be caused by physical objects directly in the way between the Keypad and the Base, like thick walls, heavy appliances, or metal mesh. Or it could be caused by other wireless devices competing for the same airspace; you're looking for low-frequency devices like remote controlled garage door openers, or wireless weather stations. Those different sources of interference can even work in tandem, so we'll want to identify them all and move either the Base Station or Keypad to mitigate their effect.

I am having the same problem, having to replace the keypad batteries every 3 weeks or so. The keypad is not located close to anything that would cause electrical interference. I do see that the lights come on when nobody is close to the keypad so perhaps this is the reason. The keypad is located fairly close to the base station and there are no thick walls separating the keypad from the base station. As a test, I will move the keypad next to the base station with a fresh set of batteries to see how long the batteries last.

My first set of batteries lasted about six months. Wen the keypad didn't work one day, I just swapped the batteries without thinking much of it. Since then, every couple days, it will refuse to turn on in the morning, and the base station shows the keypad is not responding. I pull out the batteries, then put them back in, and it work again for a while. After a couple weeks, it refuses to turn on after pulling the batteries. So I replace them. After a couple sets, I started testing them with a battery tester. They are indeed low according to the test, so I replace them. In the past three months, I've replaced six sets of batteries. The first three sets were from the same package as the original batteries, a Costco 72 pack. I bought a fresh pack, just in case the previous package was getting too old, it was close to a year since purchase. The new package is having the same issue. 

My keypad is literally next to my base station. I’m burning through batteries once a week. I finally bought rechargeable, but still have to charge them every week.
