Shortly after purchasing my Kia both key fobs and the outside push door lock will not work about 50% of the time. I cannot lock/unlock except by pushing the lock button inside the vehicle or opening with the key. I have keyless start. I have taken it to the local dealer who was unable to duplicate the problem at that time. They basically said, sorry, we don't know what the problem is. The batteries in both fobs do not seem to be the problem. Dealing with this insane issue until someone figures this out. Seriously considering selling my Kia back due to this issue and another with the suspension.
