Keyless code change Question

I am posing this question for a friend of mine, who has a 2003
Expedition. His Expy was broken into last week, one of the stupid things stolen was his warranty folder. In it was the business size card with the code to his Keyless Door Entry system.

When he realized that it was in the folder, he changed the code.
BUT!!!! He tells me, that the old factory code still works also.
So now both codes work, the factory assigned, and his
newly made up code.

Is it possible to CLEAR the old code when installing a new code????

Sorry that is the factory code, can't be changed unless you change the RAP personality module as far as I have read.

Maybe Jeff will be along to correct me, but all posts and instructions that can't be changed.

The reason I took that out of the truck, and put it in the house.

Actually the 2003MY has a Body Security Module rather than a RAP but the results are the same - the module must be replaced to change the factory code.
