You cant bypass the IMMO,
when you see this, use the other FOB
never only own 1 fob or this will happen.
"be prepared like a boy scout" and win.
a spare key is vastly cheaper than any tow truck, !

the SKIM lamp is on

the key is a RF tag chip key
what we do is .
check fuses
charge car battery if low. check voltage 12.6vdc rested or more is ok.
then scan it.
if the scans say the key is bad, it is.
if the scans tell you the skim module is bad it is.
if the scan tell you the BCM or PCM can not communicate
with other modules, you are doomed. you need pro ASE shop or dealer to fix that.

Try lock and unlock with key fob. Repeat. Open door with key. Now try and start.

2002 Grand Cherokee sometimes theft security feature does not recognize key(with electronic chip inside) and engine shuts off after 2 seconds, and orange light comes on in dash indicating a key with a...

This is not an easy problem to solve at home for this vehicle. Far and away the most common cause of this issue is a faulty PCM (the vehicle's main computer). Did the vehicle just start dooing this all of a sudden with both keys? Or did it begin with one key not working and now neither works?
There are several potential causes, but in my experience it usually a bad PCM, bad SKIM (anti theft module) or the SKIM needs to be reprogrammed.
You are best advised to have it towed to the dealer or a reputable garage with experience in anti theft systems on Jeeps.

2002 Jeep Grand Cherokee Electrical Problem

Try cleaning both battery connectors--both cable ends and posts with a common internal/external brush set available at auto supply dealers. Apply a corrosion inhibitor grease (from the same dealers) liberally to insides and outsides of posts and cable ends. Check the far ends of both cables for tightness and lack of corrosion.
