My keyless entry will stop working at random times, when i try to lock the doors from the inside of the vehicle the system will keep unlocking the front door, so I cant lock my car up when the keyless entry isn't working. Then after a while the keyless entry will work again, quite frustrating, it has a mind of its own.

This happened to me too...It turned out to be that my door was out of adjustment, which caused the door position sensor to not know whether the door is closed or open. Sometimes my light on the inside of the door would flash (because the car thought that the door was open). Once the alarm did activate, the car would sometimes think that the door had opened, thus causing the alarm to activate. It was cheap to have fixed...I think it was less than $100 at the dealership.

There is a "bar" that attaches to the lock like a lever pulling and pushing the door. Over many years and hundreds of unlockings it breaks from the plastic...I am in the same boat. It won't cost that much....take it to the dealer..the part is around $13.00 to replace

retrieving is probably not an option however if you know the factory code , you can add 1 personal code which in turn would erase any other personal codes . your owners manual should back this statement up . follow these steps >>>>>
The keyless entry touch pad can use two codes. The factory code and one
personal code .
To program your own personal code, select a 5 digit code that doesn't use 5 digits in
sequence or the same button 5 times.
Enter your factory code
Within 5 seconds press the 1/2 button
Within 5 seconds of pressing the 1/2 button, enter your 5 digit personal code,
pressing each digit within 5 seconds of the previous digit.
You can now use either code to operate the keypad

It wouldn't be the car battery, but since you just purchased the car, the dealership should correct the problem. Bring it to their attention right away. Did you get any kind of warranty? Most dealers have at least a 30 day warranty for things like this.
