I'm having some problem with my car. I just went to the gas station and it was running like normal. I got back on the highway and realised that the lights inside the vehicle cannot turn on, also the car sterio was asking for the code inorder to start playing. The car is still running as normal. But even the remote lock is not working. I had to lock the car using my keys. Help.. anyone

So some stuff inside has power, but not all. Check fuses, check battery connections.

You may have blown the regulator in the alternator. The regulates the amount of power coming from the alternator...

If you have a few blown fuses... replace them and see if they go again... if they do, take it to a shop, they can test the electrical system.
