Doors Lock On Their Own

After I shut my car off I can open the driver side door one time without it locking. If I try to open it a second time, it will lock the driver and passenger door. But I can open the passenger door as many times as I want without it locking the doors. Does anyone have any idea what this might be. I have already tried taking the fuse for the power locks out and it did nothing. Thanks in advance. Josh
