The great garage door keypad mystery that ate my entire Saturday

Our garage door opener keypad just stopped working, no lights, nothing. Figured it was the battery, easy fix, right? Swapped it out with a fresh Duracell, still dead. Spent the next hour checking the wires on the motor unit, thinking a connection shook loose. Everything looked fine. My neighbor came over, we messed with the learn button, reprogrammed it three times from scratch. Nothing. I was ready to call a pro. Then, as a last ditch move, I popped the keypad off the wall. The old battery had leaked a tiny bit, and the corrosion was on the contact spring I couldn't see from the front. A quick scrub with some vinegar and a toothbrush, put the new battery back in, and it lit up instantly. What should have been a 2 minute job turned into a 4 hour saga of frustration. Has anyone else been totally fooled by a hidden bit of battery gunk like that?

Ugh, I used to think you had to dig deep for every fix. But @benclark is right, that sneaky corrosion proves the easy answer is usually the one staring you in the face. What's the weirdest place you've found battery gunk?

Yeah, that hidden corrosion is the worst kind of problem. It tricks you into overthinking it and looking for complicated fixes. The simplest answer is usually right, but it's always the last place you check.

Actually, the simplest answer is usually the first place you should check. We just skip it because it seems too obvious. That's why it ends up being the last place we look.
