**Tech problems** My neighbours are very active 80+ and own a Mazda 3. It's a fob arrangement like my Toyota. The same as everybody, when one fob runs out of battery juice, they just go to the other one. Now, suddenly no fob works and they run to me. I showed them the key thing. Yeah! Then I took the fob apart (nasty) and the coin battery was bizarre, not in my collection. I had to do the overnight thing with ammie. Anyway, she comes running back with --there's no key thingy for the engine and trunk. So, you have to hold the dead fob real close to the ignition switch, and make sure the car is unlocked to open the trunk. whew!
