general 02 ford escape

I believe the 2002 Escape has  FORD'S SECURILOCK ANTI-THEFT TRANSPONDER SYSTEM (PATS3 ) and

The DEI 1100F bypass module, while discontinued, is available "online" for less than

The Ford PATS3 immobilizer system uses a transponder chip in the ignition key and an antenna receiver on the ignition switch to allow the car to start and run.  Each transponder key is programmed to the car.  If you purchased a plain metal ignition key, it would fit in the ignition switch and turn but not start and run the cars engine.  There are many bypass modules that allow the car to start without a working key.  Some do this thru Data and others use a transponder chip ( like the one in the key ).  The DEI 1100F is a Data type bypass.  You need two working keys to program it to the car.  As far as the car is concerned, it is just another transponder key.  The bypass module is controlled by the remote starter to turn on and off at the correct time to allow a remote start but not interfere with the cars normal operation or remove any security features.

Your remote starter system should have an output called (-) Status Output on Ground When Running that connects to and controls the bypass module.  Hopefully the installation guide explains this.

So I dont have to splice anything in to the cars security system, I just have to broadcast a radio signal at the proper time that I am starting the car, that matches the key frequency?  Thats pretty straightforward.  I dont see where the key gets energized with voltage, like contact points so I was confused.  Thanks.

I couldnt get one of those dei units in to my little town soon enough for christmas, so heres what I did.  I took the little trap door off the key, and removed the chip.  I then took the steering column cover apart and set the covers aside.  I took the black box with the black ring that surrounded the keyhole off the column and taped the chip inside that little ring.  I placed the whole thing aside.  Then I hooked up all the wires as usual, and hit the button, and it fired right up. 

Thanks for helping me understand the basics of the system so I could get the thing to work before christmas... now Im sure I can get the bypass box to work when it comes in. 

Does your remote start unit have an output called Alarm Disarm?  Most do.  Just connect that output to :
