lock problem

[hiwords1]

so my friend just got a 98 2.8 and it's in great shape. he got an extra remote and key cut for his car so we decided to program it. so we put the one that was already programmed into the ignition, and we put the one that was not programmed into the door. then we started to press buttons and turn keys to try and program it but it didn't work. can doing it wrong actually erase the coding from the key that was working? i've never heard of that happening. i also used vag com to do the remote windows, one touch unlock and the autolock at 15+mph. the original coding was 16140 and after the math i ended up with 16232 which i believe is right unless i'm going dumb. also, his button on the driver's door won't unlock the doors afterwards either. the button locks but won't unlock. the locks work fine using the key in the door method though. i'm totally stumped about this. i have the DIY from audiworld but the fact that not even the button on the door works really throws me off. hopefully somebody can help TIA

Trying to code another remote will erase the old remote(s)... when you get the coding to work, ALL remotes have to be learned by the system.

Its possible the button on the door is bad... or the system just hasnt started accepting a signal from it. When you try to learn remotes or recode the module, certain parts dont always work right away. Like if you disconnect a window motor, the auto up and down do not work right away.
