Nothing but dial locks for me. No batteries to fail, but i often take guns out or put guns in the safe during the day when my hands are not the cleanest. Having 3 or 4 dirty buttons when the rest are spotless makes the combo alot easier to guess. At least once a month someone will unlock my truck just to show me they can by randomly pressing the dirty buttons
You watch too much TV. You can set most good E locks to a bunch of numbers or a few, even the same number more than once. Most of the good one's will lock you out if you try the wrong combo too many times for a period of time, that you can set.
The problem with making a post like you did is that it may sway someone who thinks you have a valid point.
You using that as your excuse not to use an E lock is fine but I just hate to think that is the way you feel due to misinformation.
As far as the battery goes, especially as often as you say you go into it, it won't have the chance for a battery getting to the point of leaking and ruining anything. The lock starts to beep as soon as the battery is starting to get weak, either by itself automatically or when you put the combo in.
