immobilizer problem

I have a Peugeot boxer vehicle. I switch the car on and off with the remote control. When I insert the key, the starter presses the engine & nbsp; The immobilizer lamp turns off at that moment but & nbsp; starts to blink continuously & nbsp; after 3 sec. why?

Could you try to run the tool with your backup utility & nbsp;

Unfortunately, the key is single, but when I shake the key, it sounds like someone is broken, but the doors open and I open it.

A tiny chip inside the immobilizer key already got rid of its large slot. sound is his voice. I think that the light is also related to it, my friend, I hope you will solve your problem ..
