Attention parents! Got a kids' ride-on car that's stopped working? This POLYNX CSR-12T-1B 12V receiver and remote control kit might be just what you need to get those little wheels turning again! Before you order, here's how to make sure it's compatible: open up your current electric car and check the controller - if it looks the same as ours and matches the CSR-12T model, you're good to go! This is a 12V system with a 7-pin socket and uses 2.4G Bluetooth technology for reliable control. Quick note - models CSR-12T-1B, CSR-12T-1A, CSR-12T-2B, and CSR-12T-2A are all compatible with each other. Setting it up is pretty straightforward: first, turn off the car power, then pop 2 AAA batteries into the remote (you'll see three LED lights light up), then turn the car power back on. When the LED stops flashing and two lights stay on, that means you're successfully paired! If it doesn't work the first time, just repeat the process. This controller is made specifically for certain ride-on toy models, so please double-check compatibility before purchasing. Having issues? Don't stress - we're here to help you figure it out and get your little one back to driving fun!
