Default replacing the key shell... now remote key won't work.

i had 2 original remote keys for 2002 audi a8 d2.
both worked great, but i decided to replace the shell of one of them.
i was able to remove the electronic board and the transponder and put them inside the new shell.
but it doesn't work. i can't figure out how to program it again.
any tips?

Which part doesn't work? Unlocking the doors/trunk or starting the car?

Did you migrate the little RF chip (tiny crack vial) to the new remote shell?

Does the car start?
Are you needing to program the remote buttons to lock/unlock?

yes, the RF chip is called the transponder and i have taken that out and placed it in the new shell.
the car does start with the new key and the transponder, but the unlock/lock/trunk doesnt work.

before i relocated the transponder, when i place the batteries in, the car sounds the alarm, so something is working.

Unlock the driver's door with the key and then press a button on the remote. That should allow the remote lock/unlock to work again. If not, check the remote battery.
Your issue kinda sounds like there is a button stuck down on the remote and that can cause the panic to sound and will drain the battery.

i switched the two remote's battery with each others and the old remote still works fine.
the new one is not responsive at all. i did what you told me about unlocking and pressing a button.
i think i may have ruined the board when i was taking it out of its old shell. i had a hard time removing the 2 circular gold colored screws that were holding the board down.
is there a way i can fix such things?
