Re: replaced battery,car will not run properly
Often if battery fails or is disconnected for a time the car will want to have readiness reset. this is best done by a tech using vadcom or vcds software , however alot of the times if there are no other problems ,taking the car for a ride for a bit will let it set readiness on it's own. let car see road speeds from 0 to about 55 mph and give it a few key cycles while driving, meaning ,stop ,park car, turn off ignition and then restart and continue driving. if it doesn't reset within 15 min or so it most likely will have another problem so watch for the mil light to come on during drive. good luck

I also have a 1999 El Dorado, with 188,000 miles. First my TCS light came on once because I was really racing the car. The car's system went into "reset mode" turning off all of the car's computer controlled functions, Starting with TCS, A/C, ABS etc. This was due to the battery or alternator failing to supply enough electrical current under extreme demands for power and performance. I ultimately had to replace my alternator $450.00. Second, I had a "Check Engine" light on because my transmission was not shifting at the proper times. The computer had to be reprogrammed then the shift pattern was fine.
You should check to see if you car's alternator is working properly by starting the car then disconnection the battery cables while it is still running. If your car still runs, then your alt is okay.
I would also have the transmission's program codes checked and reset if necessary to shift at the right time. When they hook one of those Caddy scopes to your car's main computer, it spits out a series of codes. I do not know how to read the codes, I just know that they can be changed to make the car's performance better. I hope this was helpful.
My immobiliser keeps flashing until I put the key in the ignition and then it stops. Normally changing key batteries has a period that if the battery is changed inside that time (say 5 minutes) then the key program will not loose memory Run fault codes to see if there is a problem in the electronics. Otherwise you may have to take the car to the dealer to have the key reprogrammed to the cpu in the car
YOU CANT REPLACE PCM AT HOME BECAUSE YOU NEED SPECIAL DIAGNOSTIC EQUIPMENT TO REPROGRAM THE NEW PCM.YOU NEED GM SCANNER THAT CAN REPROGRAM RELEARN CKP AND CMP.RELEARN IDLE AND REPROGRAM THEFT SECURITY SYSTEM.
There is no shutoff switch or reset button. The first place to look is the key fob itsself. If you know the battery is good, then check the solder connections on the battery clip. These often break, and render the FOB useless until it's re-soldered. Next, clean the contacts where the buttons press against and the back of the button pad with alcohol. This gets any deposits off. If it still doesn't work, you may have to reprogram the key fob. The instructions can be found in your owners' manual.
Newer Dodge Vehicles do not have an ignition for a "metal" key. They use the Electronic Key called a FOB with a built in or integrated metal key that is only used to unlock the door. The FOB inserts into a WIN module (Wireless Ignition Module) instead of the normal igition. Reprogramming the vehicle usually does the trick however there has been significant problems with the WIN module and the dealer may have to replace it. The 2010's have a recall on some models. The manual states the keys cannot be reprogrammed. The first and easiest solution might be to try replacing the battery in the FOB (aka key),
