In my case, my car is an Infiniti/Nissan but other cars may be similar..... How long does the battery last in people's keyless start key fob ? I try and use VARTA (used to be made in Germany) or Energizer batteries but it seems like I'm replacing them at least twice a year (or more).
This latest time (today), it gave no warning of a low battery (in the dash) and the fob was pretty much 100% dead. Car would still start by inserting the fob into the 'hole' but you couldn't lock or unlock the doors and after starting, when you remove the key from the 'hole', it said "No Key" in the dash (car still runs though). My wife drove it today and ran into this but since the car was at home, it wasn't locked. If this happened elsewhere, it would likely have been locked and would have been an annoyance !
Almost tempted to keep a 2032 battery in my wallet at this point.
