keyless entry on 05 ST?

[Cerevus]

So i just bought a 2005 sport trac and it doesnt have a keyless entry system. Im wondering if its compatible with a new system for it? And if it is can someone give me some links to a few i could buy? Thanks.

As in you don't have a key fob?

turn the key in the ignition back and forth 8 times, doors will lock. Press the key fob and the doors will respond to the button and you are done.

I meant it has no receiver for a key fob.
