Keyless Entry

I recently bought a 97 Ram 1500 with the Magnum 360. Is there any way I can find out if there was originally keyless entry with this truck? Or if it is set up for it and I just need to buy remotes?

all dodges now adays are vin specific call the local dodge parts counter tell em what you want theyll ask for the vin then they can tell you every thing about your truck,color,gear ratios,trans,everything
