You will need to perform a factory reset of the Batmobile RC vehicle. **The Batmobile needs to be on all four wheels to do the reset.** The battery compartment is located on the left side of the vehicle. Remove the battery door and locate the small hole on the bottom left hand corner of the battery housing.  While the Batmobile vehicle is turned ON, insert and press down the reset button located in the recessed area for 10 full seconds using a paperclip or similar sized tool.  After holding down for 10 full seconds, release the button, wait 3 seconds and then cycle the Batmobile OFF and then back ON, and follow the "new user" instructions to connect to the Batmobile in the Batmobile RC Controller app.
