if you do not already know the factory code, the only way it can be obtained is by your local ford dealer. the proprietary computer equiptment they have can access the code that is programed in vehicles security module. if you purchased it used..it is often that the keyless entry code id card is still withe the owners manual..it is a 5 digit code printed on an credit card sized card that is white in color..i hope this helps you...good luck

The code is on the fuse box under the dash near the hood release. On my van there are two bar codes on a sticker attached to the fuse box. Under the first bar code, on the right side is the 5 digit code (bring your glasses the numbers are really small). After you get this code, just search the internet and there are plenty of forums on programing the keyless remote and also adding your own unique number to the key pad entry.

Good Luck
