My engine won’t start battery not working car won’t crank windows wont go up

Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. I’m sorry to hear you're having trouble with your Altima. It sounds like you’re dealing with an issue that could be related to either the battery or the key fob communication system. If the battery is dead, it can prevent the car from starting and cause issues like windows not going up, as it can affect electrical components. The error message with the key may indicate a problem with the key fob or the car's security system not recognizing it. First, try using a spare key fob if you have one. If the car still won’t start, you might want to test the battery voltage. If it's low or dead, replacing the battery could help, but if the issue persists, there might be an issue with the key fob system. If you need more advice, have any other questions about your vehicle, or would like to get connected to a RepairPal Certified shop near you, we have you covered. Give us a call at 877-913-1554, and we will happily help you out!
