Dodge charger door locks

Ii have a 2010 dodge charger. Recently it has been unlocking on its own,sometimes when using the key fob it will not lock. It unlocks its self even when the key is in the house and I have not bumped it.I have changed the battery in the key fob, but still no luck.Any ideals?

It sounds like you could possibly have a faulty door sensor. Which can cause the doors to unlock or lock on there own.
