What is the code to reset computer when battery disconnected?

No symptoms posted,so all anwsers will suck, mine too....
there is no code.! sorry NOT. (wrong guessing)
but how to start fresh? Ill answer, (ran ok before battery new, is my wild guess)

pull battery say for 5 minutes (let all elecronics discharge to zero Volts)
use a good charged battery , that means 12.65vdc rested.
be sure to connect Plus lug last. (off last, on first)
now key on.
does the IMMO lamp (SKIM) go out? yes/no
immo means immoblizer using generic names, not jeep names.
does the CEL lamp in the cluster go on key on, it MUST.
does engine crank now? yes/no
does engine start now " is IMMO flashing...
do say ?

When the anti theft system was created,the dealers forgot to tell the new car buyers about how much the fob matters to the vehicle,without it,owners are stuck,your anti theft device is activated,you need to lock and unlock your doors a couple times with the key fob,not the key,and then you need to put the key in the ignition and start it,if you dont have your key fob,call your car dealer to get a new one,they are programmed for each car only,you cannot bypass it.if you lost your fob or never had it,whatever,you need to have the exact fob that came with that car from the factory,the key and fob have a chip in them that only go to that certain car,if you do not have it,then you need to buy a new one from the dealer or ebay and then you need to contact your dealer about programming the fob to your car,you might not have to have it towed if they have the documents from the car,the only other way is to get a junk car,with the steering column,key,fob and all computer boxes and door locks and switch them,i just did that with a 98 dodge dakota,and it works.
