Whenever Im driving my car the automatic door locks keep trying 2 lock repeatedy

What is your question?

for 2 days now, when i drive my 09 dodge charger the automatic door locks go off repeatedly for a few clicks and then it stops for about a minute and then repeats, i have also noticed it only does this throughout the afternoon when its hot outside, works fine in the morning and at night (only had two days to test the theory on whether it is affected by hot weather). I have also changed the battery after talking with my mechanic.....did not fix the issue. any Ideas?
