Question about 2003 Jeep Grand Cherokee
Sounds like your Sentry Key Immobiliser Module may be at fault. That's a Main Dealer Problem. Try disconnecting the battery lead for a minute or 2 then reconnect. Red.

The door security has nothing to do with the jeep no starting. Check your electrical leads and also terminal leads that run to the battery. If you can, get your battery and your alternator tested to see if theyre any good. If your dash indicates the following while driving;" Transmission Overheat", then, with the engine running, check your transmission fluid level. If the transmission dipstick indaictes that the amount of fluid is low add maybe a quart to it. if you do this again and you find thats its doing the same thing, then there might be a couple of things wrong;
- 1. You may have a leak somewhere. Check your lines and check around the transmission pan. If you find a leak around the pan, than that means that you need a transmission filter kit. This includes a pan gasket and filter.
- 2. If you lift the hood and look over to the left (standing at the front of the car) and find the reserve tank to have a dark color liquid in there, open the top and see what color it is. If it smells and looks like Transmission fluid, then that means you have a busted radiatior. If you open the radiatior cap and look down into it and see the that the color of the fluid is a pepto bismal- looking color, then its deffinatley time for a radiator replacement and flushing of old fluid out of the system.
-3. Transmission is burning up gears and needs to be replaced. i dont know what jeep was thinking when they put a three speed transmission in a car of that size that idles high beacuse of the gears, when it should be a five speed that idles lower being thats a bigger size car.
-4. Check your fuel lines and your fuel filter.
-5. The sensor that sends a signal to the number one cylinder to fire may have gone bad and needs to be replaced.

It's most likely, looking for a security key, not a regular key. Security keys have a chip in them, to identify them as a valid key, not a screwdriver. It's a passive anti theft device. Available from the dealers.

Somehow, your security key becamed unrecognized by your security system. I don't exactly know the fix for this, but maybe the dealer can tell you what to do next.
