As the title states, I have a 05 Sport Trac, just plain Jane. No keyless entry, no remote start, no steering wheel tilt. Just standard. I am wanting to install a Viper 4103 remote start/keyless entry kit to it. I just don't know if I will need any extra parts? I've tried googling and all kinds of stuff but cant find a straight answer. Some sites say I need an immobilizer bypass, some say I don't. Can anyone help me before I go and spend the money finding out that I'll have to spend double.

 

I'm 98% certain you'll need a PATS/Securilock bypass module. Unless your truck was a previous fleet vehicle and the passive anti-theft was disabled, you'll need a bypass module. You'll also need to have at least two keys for the truck that are already programmed in order to program the bypass module to your truck by yourself.

There's at least one manufacturer that identifies what kind of passive anti-theft system the vehicles on the market use. I think Ilco is one such site as they are a popular aftermarket key manufacturer.
