I have seen advertisements on e-bay for the keyless entry remote for the Ram, can I buy one and use it for my truck if I haven't got one now???

 

As far as I know you would still have to get the "brain box" that goes under the dash. I could be wrong though.

 

Look under the brake release lever. If you see a small button then your Dodge is equipped and ready for keyless entry. If you do have the button then reply back and I can get the sequence of events necessary to program you keyless entry and alarm....
