Car will start with jump leads but when ignition switched off all lights on dash go out and car won't start
I cannot see the problem because if the ignition is switched off the dash lights will go off and the car will not start. That is normal. If what you are try say is that when the jumper is removed the car stops and the dash lights go out then the problem will be a dead battery.. Have a load test done to check for a dead cell

Yes the key needs to be reprogramed to the car. Unfortunately that will have to be done by the dealer. Make sure that you have plenty of proof that you are the owner. They will reprogram it but you will not take posession of the car until you prove it is yours.

Could be your alternator. If you can get it started again. Try to have the alternator checked out.

Hello Kurtzuba.
Actually, although rare, this could be a computer issue.
The voltage regulator is built into the computer on your Concorde and may not be completing the circuit.
I'm not sure how you verified the alternator is good other than you removed it and had it tested.
To verify the problem is in the computer, find the orange/dark green wire that supplies power to the alternator.
This is fused power to the field. Verify it has 12.5 volts positive. If not, that will need to be repaired.
If it is OK, then find the dark green wire that also hooks to the alternator.
This wire leads to the computer which controls the amount of ground to regulate the amount of output from the alternator stator.
Attach a wire with an alligator clip to the dark green wire terminal on the alternator.
Attach a voltmeter to the battery.
Start the car and touch the other end of the attached wire for a few seconds (no more than a minute) to the NEGATIVE battery terminal.
If the alternator begins to charge you will need to verify the green wire is good to the computer.
If OK, replace the computer.
If you need more assistance with this issue, let me know here.
Thank you for using FixYa.
