TJ doesnt start with a key but does with...

Start simple. If it's standard shift, does it have a clutch safety switch? If it's automatic, check the neutral/park switch. You can eliminate starter, solenoid, battery and cables. Also could be the ignition switch. I don't think the remote start would interupt that. But if you have a burgler alarm it could be at fault.

The security system is at fault here. It has opened the starter circuit because it thinks the vehicle is being stolen. It's happy to start with the remote because that is a different part of the control module.

Well, if I was a betting person my money would be on the aftermarket remote starter. If you have the Sentury key system then that is the problem. You cannot use a remote starting system with the Sentury key system it is one or the other. If you do not have the Sentury key system the installers have hooked up incorrectly and by-passed your starting circuit that your key uses. Any how, it is your remote starter that is the problem.

So you start it with your remote and then what?!?!

I always thought that when you used the remote starter, you still have to put your key in the ignition to be able to drive away (else it would kill the enginer on you!).

Could it be the encoded key??

I start it with the remote, then when I get in, I turn my key over to kick it out of "remote start" mode as you have to do with remote starters.

My Jeep is a 1998, I dont have an encoded key nor a Sentury key system.

Most are saying it's my alarm, so I am going to have it checked out by the shop that installed it 6 years ago. If they find nothing then I think I might start with my ignition switch.

Thanks for your advise guys...
