Why wont unlock with key and wont start

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your Accord is dealing with a power issue. If the key fob isn't working, and you can’t manually unlock the doors, it’s likely the battery is completely dead or there’s a problem with the electrical system. You were able to get in through the trunk, but since the car won't start and there's no noise at all, it's probably the battery. Try jump-starting it. If that works, great—just check the battery and alternator afterward to make sure they’re holding a charge. If not, you might have a deeper electrical issue like a blown fuse or a bad ground. If you need any further advice or want help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554.
