I had the same problem with my tradesman. Has a key - no keyless and I hated it after 3 days.
So I bought a Viper 4105V - remote start and keyless entry. Love it cause I didn't want an alarm. The guy told me I could use my phone to start/unlock it. Thought that was a cool feature. So I assumed the 1way didn't matter since I could use my phone.
Turns out - you have to pay for that feature. Which kind of sucks cause you don't get a 'confirmation' that your truck actually started. But I can see it from my office so I just look for the lights to flash. A good 400 feet way - no problem. Says 1500 foot range.
I also do 2 of the 529T for the front windows and a rear 530T unit.. so my windows are now all one touch - go up and down with a press of the button and can crack if I need to from a distance.
I always roll with my windows down. So I like getting to the place, jumping out - pressing the lock button and my windows go up. I don't have to sit and wait
I know lazy.. but it's somewhat cool to have.
