as long as the engine codes match they will fit. 2003 Ford Escape 2.0L VIN "B" 2003 Ford Escape 3.0L VIN "1" 2004 Ford Escape 2.0L VIN "B" 2004 Ford Escape 3.0L VIN "1" 2005 Ford Escape 2.3L VIN "H" 2005 Ford Escape 2.3L VIN "Z" Hybrid 2005 Ford Escape 3.0L VIN "1" 2006 Ford Escape 2.3L VIN "H" 2006 Ford Escape 2.3L VIN "Z" Hybrid 2006 Ford Escape 3.0L VIN "1"

The original door code was indeed on a card with the owners manual. If that is gone, the door code is on a module inside the center console on 2008-2012 Ford Escapes. There is a discussion with pictures at one of the Escape forums: http://www.escape-city.com/viewtopic.php?f=28&t=8215

I had to find my code on my 2012 Escape.

most of the time the will give you the code. it takes a scan tool to pull the code out of the computer but there may be a way to change in the owners manual

Had this code for over 2 years on my 02 escape. FINALLY, found the solution. DONT replace your egr vacuum solenoid (unless you see broken pins on the connector). You can always test the solenoid to see if it still works if you suspect the solenoid is the culprit. Rather, most likely the problem will be in your electrical harness that connects from the solenoid to the pcm. I had no visible broken wires. However, in my case, my female connector harness that plugs into the solenoid was faulty. Replaced it by soldering the wires from a "new" harness that i got from the junk yard. If this fails for you, the problem will be almost guaranteed to be in either your pcm hardware or a broken pin at the pcm connection.

on my 2010 ford escape XLT i found the keyless entry code printed on a label on the smart junction box which is inside the center console. To get to the smart junction box follow these instructions.
1. with a non-marring tool(i used a putty knike wrapped in plastic wrap), pry up the chrome trim piece around the shifter.
2. Remove the storage tray from underneath the center console armrest and leave the armrest cover open.
3. Grab the center console finish panel near the cupholders and pull straight up.
4. Pull the finish panel up and back then set it aside.
5. The smart junction box is to the right and slightly ahead of the gear shifter. There should be a label with a bar code that says FoMoCo. In the corner of this label is a 5 digit number. This is the factory code.
Hope this helps.

On alot of cars you must erase the code after repairs,the code is pending in the memory and can still run bad till cleared.try clearing the code
