I drive/bought a used 2002 BMW 325ci and one day I took the keys out of the ignition and the car started beeping, i checked if everything was closed, (lights, trunk, gas door, car doors, and trunk) but it still kept beeping... then on top of that, i couldnt lock the doors with the key button, but it works manually. So now, every time i open the door, the beeping occurs without the lights being on. I took it to a friend at a dealership and he thought it was just the key, but when i got the new key, we could not reinitialize it. He does not know whats wrong with it, so hes going to look into it a little more. This all happened after i installed angel eyes, which my friend at the dealership said might have caused all this. Does anyone know what could be wrong?
