Car won't start, but engine turns over.

SOURCE: how do i override/reset anti theft system?

this does not sound like an antitheft problem. the SKIS systems in the jeeps will allow the truck to start, but it will turn off again after 5 seconds.

FYI if your jeep key is gray, it has the SKIS system. if it is a black key, it does not.

have you already done diagnostics for a no start? if you are lacking fuel or spark, you need to look elsewhere for the problem if it does not start at all. good luck!

With the doors shut, insert the key into the drivers door lock. Lock and unlock the door 5 times. This should reset the system. If that doesn't work you should contact a qualified repair shop.

Have you chaged the battery on the remote. And also do you have a valet button under the dash somewhere if you push it for about 15-30 sec. it should reset the alarm. if it fails you might need a whole new alarm system.
