How to operate keyless entry on 1998 ford explorer?

Keyless entry usually means an FOB comes with the car and you push the button to lock and/or unlock it.

What exactly do you mean by keyless entry? Are you referring to a wireless remote to lock/unlock doors? If you're talking about modern-day keyless entry (doors unlock by being in close proximity to car), then that model year car did not come with it from the factory. If the car has it, it's likely aftermarket.
