Gen 3 Tacoma no keyless entry. Help

I bought the truck without keyless entry. I have pwr locks I don't think it should be that hard to add keyless entry but can someone help me/ explain what i need. Do I need have to add a computer or ?
Also I work for toyota as a body tech. I'm sure I can do what ever is needed.

 

Also interested in this, I hope you get an answer.

 

So you work at a toyota dealership in the body shop?

When comparing price to functionality, hands down, you will be better with an aftermarket setup. Hell, you can get remote start setups that will lock/unlock your doors for under $100.

 

im confused? you work at Toyota and you have ZERO service techs you can ask to help you on the technical aspects?
