If you question whether or not your VX even has the keyless entry module in it, look up under the drivers side dash, to the left of the steering column... there will be two black boxes on brackets. The keyless entry box has three plugs on it, one plug has only one wire (white or light gray), the other plugs have 6-8 wires each... if that box isn't there... well... maybe they put it in a different place in 99... but doubt it.

TTYL!
