I have a 2012 Toyota Rav-4, I use the original key fob to the car and I have a spare. The car is push to start (keyless) and this morning it wasn’t recognizing that the key was in the car, so I couldn’t start it. The fob has also been slow to. . If it turns out that storing your key fob next to your cell phone each night as it charges eventually causes the key fob battery to fail prematurely, then maybe consider moving the key away from your phone- but I wouldn't necessarily do that unless you experience a problem. The key fob battery is. . Leaving a key in the car drain battery is a common mistake that can have severe consequences. When a key is inserted into the ignition and the car is turned off, it can cause the battery to drain slowly over time. This can lead to a range of problems, from a weak battery to complete battery. . But is it possible that your key fob is the culprit when it comes to your dead battery? “A key fob will constantly try to communicate with the car. And that does cause a slight drain on the battery, but generally that won’t completely drain a healthy car battery,” says Mike Monticello, Consumer. . A parasitic key fob left inside a car could be silently draining the battery, a concern highlighted by TikTok mechanic Brandon Sloan (@performancetransmission). In a video posted on November 12, Sloan explains the risks of leaving your key fob inside your car, and shows why Yukon models are.
