Please help figure out how to add factory keyless entry!

[cjmiller]

So my van has power locks but no keyless remote entry. Do I have to get a SJB from another van to be able to ad keyless entry? I know where I can get a donor van. Is that all I would have to do besides doing the forscan thing? I thought you also need a module by the passenger side foot panel. The donor has something there but mine doesn't. Not sure what year the donor is. I tried adding an aftermarket system but can't get it to work. Please help. I can't stand a car without a remote.

Do you have TPMS?
What year? (This determines the passenger footwell thing, boundary being 2008/2009)
If you have power locks, its worth ordering the remote and having a try.
