Will not start, there are no lights on the dashboard

It sounds like one of two things either the battery is weak and needs to be replaced or you have a bad connection at the battery. I would start by cleaning the cables and then load test the battery which you can do using no tool by following the guide below:

I have included how to replace the battery in your car in the diagrams below. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

We located the problem to the unit controlling the key and security. i think the part number is P05026529AB ?

Is the security light flashing when you try and start it? If so, let's try a hard reboot to the system by removing the negative battery cable and holding it against to positive battery terminal for 1 minute, this should discharge the capacitors and let the system relearn. If this doesn't work, it sounds like the TIPM is out but to be sure you can get a CAN scanner from Amazon for about $30.00. here is a video to show you how:

I have also included the TIPM replacement instructions which are easy because it self initializes. Check out the diagrams (below). Please let us know what happens.
