Finally got around to replacing both batteries, and it resolved the issue, no more key blinks. I read in another thread that the keys are constantly listening (makes sense, it needs to sense when you push the unlock button on the door itself), so both batteries would wear pretty evenly, even if you only used one (like myself). So that's just over 2 years of battery life for $3.99 (2 pack of CR2032), not bad. I'll be back to this post around April of 2019 and we'll see how long the Energizers lasted compared to the Maxell or Memorex batteries, or whatever was in from the factory.
