The factory alarm keeps going off on my audi a4 especially when it gets above 100 degrees outside. What could be causing this?

I tried the same thing of switching the heater on in the afternoon and nothing happened. I don't know if it was just a coincidence.

starter turns but don't want to start ,but when u push start it ,it stars.this happens 3 to 4 times a week

and the light is blinking. It stops for a while and come back on. What might be the cause?

A week ago my key simply kept turning in the ignition and was locked in place. I had the part ordered and have the trim and old part off. Also the steering is currently locked as well. I have the new part connected to the electrical and in the cylinder but there's no way to keep the part in place and the key has to wiggle to even allow the switch to fall all the way in place. It will allow me to push it in but the key wont turn and I can only get power, no engagement on turning the starter at all. Any advice or questions for more detail are greatly appreciated. Thank you.
