Remote Starter - Jeep 2002 Libery Sport

You did not mention if it is a Factory installed, or after market keyless entry (and you might not know) If it is an after market system and it does not have the auto start feature you will need to buy one which has that feature and remove the old system and install the new one, (sometimes you will see a small led light drilled into a trim panel on after market systems ). Idont know your mechanical abilities and there can some times be a lot of wiring splices to make. So if your not comfortable or if anything I just said seems over your head, maybe hire it done.
