1999 Concord Secuirty Codes

Reset Concord security codes


I disconnected the battery to do some work on a car audio system. By doing this, and NOT applying a small amount of voltage to the electrical circuit that feeds the computer, the security codes are erased.

My remote door locks don’t work, no interior lights, power locks and trunk don’t work. I can only open the doors and trunk with the key.

Last time this happened the dealer charged me $100 and 2 minutes later they had reset this codes.

So the question is, Does anyone know the procedure on how to reset these codes?

Thanks
