Re: 1999 Contour Keyless Entry ...
I don't know if it is the same as my 1999 Escort, but you could try it.
Place key in ignition and turn from off to on in rapid succession 8 times (within 10 seconds), ending in on. After doors lock/unlock, press any control on all transmillers. With each press of the transmitters, the doors should cycle lock/unlock to confirm programming.
