OBD-II Code P0480 is defined as a Cooling Fan Relay 1 Control Circuit
The purpose of the electric cooling fan system is to provide extra cooling capacity to the conventional radiator cooling system on hot days, and/or when the A/C is on, and/or when the vehicle is being driven in stop and go traffic which causes insufficient air flow over the radiator. 25 years ago, most cars and light trucks utilized a mechanical cooling fan attached to the front of the engine to increase air flow through the radiator. However, as fuel economy and low emissions became a high automobile design priority, vehicle engine cooling systems incorporated computer controlled electric cooling fan systems and abandoned the less efficient mechanical cooling fan.
When code P0480 is triggered, the power train control module or PCM is commanding the cooling fan to operate, but the PCM is not seeing the proper electrical feedback from the cooling fan circuitry that would indicate the fan is operating properly.

I'm assuming this is the factory fitted alarm. This could be more than one possible answer. First check the silly stuff. are all the doors and tailgate closed correctly? A sightly open door switch could trip the alarm system into thinking the vehicle is being stolen. Is the battery on the Jeep fully charged? A low battery charge can cause alarm systems to throw a tantrum as it's not getting the correct signals from the alarm sensors. If the key has a battery in it or it has a separate alarm key fob check the battery in that as well. When you insert the key it is supposed to communicate with the vehicle's immobiliser/alarm system to allow you to start the car. It sounds like this isn't happening.
Are there any 'new' warning lights on the Dash display? These can give clues to where the issue could be. How are you turning the alarm off when this does happen? If these check don't solve the issue there could be an actual fault with the alarm system itself. Remember this is a 24 year old Jeep and Alarm systems do get old and develop faults. You may need to get an alarm specialist to look at it as they will have the specialist tools to test it. Sadly that will cost you money.
They are 4 wheel drive so that needs looking at professionally. If I remember that is something that happens to the differential if you turn corners on paved road in 4 WD. It is supposed to be used on soft surface where the wheels can slide if needed when cornering. Here are the details. If I remember, you jack one side up and the wheel unwinds, then you do the same on the other side. Have a read.

No, unfortunately you can't, it has to be programmed with the mileage of the vehicle and also with the VIN Number.
You would need an auto electrician to do that, so you might as well call one to get the problem diagnosed and the anti-theft reset. The is only one reset, it is not a phone that has a 'soft' and a 'hard'. An auto electrician will have a professional grade $5k bi directional scan tool computer that can quiz and diagnose all the modules involved with the antitheft system and immobilizer.

Question edited for clarity.Question moved to model category.It could be many things and it is no good guessing. An auto electrician can connect a professional grade scan tool computer and record what happens at the moment it stalls. It is more cost effective that guessing and swapping out parts.

There isn't one. The sensors are powered by and monitored by the Integrated Power Module (an all encompassing ECM/BCM/[PCM?])
Did you Cancel / Delete the code after changing the o2 sensor? You have to to make the light go out. I use this FIXD Scan module that displays to my iPhone. It will cancel codes.

Or as Paul says, the issue is the plug or the wiring to it.
