Changing battery engaged anti-theft system

I have a 2013 Wrangler Unlimited Sport 4-door hard top with freedom panels. The battery died I tried to jump it with a booster, but no go, so I used the fob (it has the keyless entry system) to disarm alarm, changed battery, then tired to start car, no go, it started, ran for a few seconds, then died, did this a few times, now it won't even attempt to start, gauges all work, the anti-theft system has been engaged. Had a similar problem when someone tried to steel the battery out of another 2013 Wrangler, ended up taking it to a dealer, don't want to do that again, unless I have no other choice. Is there a way to reset the computer? I have tried to lock and then unlock using fob, the fob works fine, tried disconnecting battery for at least 15 minutes and reconnecting, leaving key in ignition in on position, nothing has worked, any ideas? Thanks.

Just an update, mechanic looked at Wrangler, the brand new battery that I purchased was drained down, he thinks there is a short somewhere and something is drawing on the battery, now it is just a matter of locating it. Anyone have any ideas?

First place I would start would be with any after market electrical add ons. Not sure what you have, but try disconnecting them all and see what transpires. If you have no after market stuff, I would let the dealer " Deal" with it!

I'd start by pulling fuses. You'd need an ammeter to look at the draw.

I second this advice.
