Not all the time but 95% of the time it takes three or more tries to start my vehicle. It does crank however it eventually stops cranking and my doors will unlock as if I am shutting the vehicle off. When i turn the car off my doors unlock. When i try to start it the doors unlock on their own. Sometimes it starts perfectly fine. Most times it gives me this headache. I replaced the pass-lock and ignition, and also had my complete computer system reprogrammed including the BCM. Any suggestions?

Yes, sounds like the battery is going bad.

Here are a couple of guides to confirm and fix the car:

and

Make sure both cables are clean and tight.

Please let us know what happens.
