The batteries in the car are located between the two rear wheels on the car. They are covered by a plastic casing, which is held on by a screw. The screw can be unscrewed using a Phillips PH0 screwdriver and turning it counterclockwise. For step by step instructions, please refer to the Car Batteries Replacement guide. When you replace the batteries, be sure to insert them in the correct orientation or your car will not turn on again.
Well, there are a few possibilities why the car is not responding to the remote control. The first is that the batteries in the remote are dead. If the batteries are dead, power will not flow to the controls or transmitter. To fix this, you can replace the batteries. For instructions on how to replace the batteries, please see our Remote Batteries Replacement guide. Another possibility is a loose wire inside the control. The remote works when electricity flows through the control. For the electricity to flow, it needs direct contact between two conductors inside the controller. If the wires are disconnected, you will have to replace the board in the remote. To replace the board, you can go to our Circuit Board Replacement guide. If you have multiple cars, you can test the remote by using it on the other car. If the other car will work, then the issue is with the car not the remote. In that case you can take a look at the guides for repairing the car.
