How can I reset the entry code on my 99 expedition?

I bought it at an used car dealer and they didn't know the code, is there any way to reset it?

How can I reset the entry code on my 99 expedition?
I work at a Ford Dealer. The dealer can pull the Code out and it is also on the Module. You cannot reprogram the master code it will always work. you can add your own code into to make it easier to remember. To do this you first out in master code then push the 1/2 button then enter your 5 digit code It will cycle the locks when it accepts it.
Reply:There is no way to reset the code. It is built into the module. Thus anyone that knows the code can get into your vehicle. If this is a possible concern for you, replace the keyless entry module. Either way, the module is directly above your left foot when sitting in the driver's seat. It's way up high, and is a white square box with a sticker on it that has the 5 digit code for the doors.

Reply:The keyless entry code is printed on the label of the control module. Look under the dash on drivers side. It will be a small black plastic box. The code is 5 digits.

Reply:You need to get the master code, it might be on a sticker on the hatch or behind some interior trim, check the owner's manual
