Well, the 20 year old remote for my pickup truck has been not acting as it should. First guess, based on experience, is that the "coin" batteries- 2 2016 size were getting weak. Off to the hardware store for some fresh ones and they had Duracell so that is what I bought.
This remote has 2 batteries that are stacked in the remote's compartment and after replacing them- nothing. After some meter work and some other messing around, with a magnifying glass I was able to spot what looked like a well-spread spot of sealer on the negative side of the battery....Could it be part of the childproof coating? Yep, the coating, as thin and hard to see as it was preventing the "stacked" coin batteries from transferring the voltage from one battery to the other.
A rub on a glass plate with some emory cloth to "surface" the coating resulted in the surfaces to make contact again and the remote is back working.
Just in case someone has a device with stacked "coin" style batteries, it may be better to seek out the Energizer brand.
