DEI 555f

Greetings all,

I am having a Clifford RSX 3.5 with Remote Start installed in my 2005 F350.  I understand that a 555F unit is required to bypass the chipped key protection.  Can someone who is truly familiar with this unit elaborate on how it functions?

My concern is that I have heard of installs that required putting a key hidden somewhere under the dash, or removing the chip from a key, etc.  I am really not interested in leaving a key   (or any physical part of a key) inside the vehicle if I don't have to.  I got the impression that maybe these units get registered with the onboard computer as if they were their own key, but do not actually require leaving an actual key.  Can someone clarify?  I know there are a lot of both good and bad installers out there, I just want to be sure I am dealing with a good one.  :)

All this box is doing is translating the signal from your key to your ignition. This process is only done during the remote starting process. The point of the chip being in the key is so that your truck will not start with anything else but that key. All of those features still work on the truck its like I said previously that the purpose of the "key in the box" is only there to bypass that security feature during the remote start process only. There is no other way around it. Every bypass box that you use (brand) all require a key.

The way the box works is that there is a copper coil that comes from the box and wraps around your ignition. This you wont be able to see. The key is placed into the box. Now when you remote start your vehicle, the remote starter sends a + signal to the bypass kit that turns it on hence , sending the signal of your key to the ignition, then the vehicle remote starts.

I hope this helps you to understand a little better as to how these modules work.

I would check to see if you do have a transponder based anti-theft system first, you may not need anything.
