Where is the key pad code located on an '05 Expedition EB?

If this is not written inside your owners manual you will need to get a new one from your dealer. This information is stored in the BCM and may need to be pulled or reprogrammed from there.

Remove the fuse panel cover on the lower right passenger side, next to your feet. Look up in the opening at the metal box which has a bar code label on it. The 5 digit number is the original key pad code. You can add your own code in addition to this. A dealer wanted to charge me $100 to 'hook it up to his computer' to pull the number! lol
