Did keyless entry come standard on 98 Sr5?

[Del34]

I've been starting to ponder this because when I bought my truck, I never even received the master key, so I've been wondering if there's the possibility of the keyless entry system already being installed and all I would need is a remote.

Anyone know?

The control unit would be a square plastic box located under the drivers seat. You should be able to see it by looking under the seat. Also you should have a red light and speaker mounted in a cut out on the dash or center by the shifter.
Go to this link to see a picture of the unit and for programming info for a remote.
