STERLING Remote Control for PRO DIGITAL High Performance Controller

In order

My sterling remote hangs at about 6.-7. x start my car and then have to be disconnected to work again. Have sent the part already to the manufacturer where I got it back with the same answer, no error could be detected. Also the voltage display shows too little voltage. That is, if the correct voltage of my batteries is 12.6 volts, the display of the Frenbedienung indicates 12.2 volts and low battery lights up. "" "" Annoying "" "" If I had not cut the huge hole in my center console for this would have been useless part wandered long in the trash. Unfortunately, you can not forgive minus points.
