I have the same problem, the keyless system is not working. In addition, the lock/unlock buttons inside the car also do not work. Taking it to a mechanic today to see if the problem is a simple one so as to avoid taking the car to the dealer.
Yeh I just replaced the two fobs with multiple batteries and still no joy'
Keyless entry/lock works about 2/3 of the time. Have now replaced the key fob batteries in both keys twice inside of 6 months. No resolution, looking for further troubleshooting thoughts/techniques.
Second back up key also stopped working after 2 years of use...

The key stopped working after the car battery died and was recharged.
Was told it needed 1000 repair. But was able to use by taking out key and using remote all the time to start car. Trying to see if I can avoid $1500 repair
