I replaced the battery on my 2003 Audi A4. Keyless entries are no longer working. Also noticed the truck pop-up on the truck lid does not work and truck light does not come on after the truck lid is open. I have tried "Resyncing Remotes to the Car" https://www.audiworld.com/tech/misc.html and the owner's manual instructions, but did not work. Fuses are okay also?

Any suggestions recommendations?

Something similar happened to my 2004 after disconnecting the battery for a long period of time while I was replacing some part in the engine. Even the automatic window lower and other features did not work, however after a day or so they all started to work normally, like if the on board PC and the electronic finally got synchronized...

put the key in and turn it to the on position.
then let then sensors adjust and click the lock/unlock buttons while the key is still in.
Then turn the car off and see if it works.
It should work. HOPE THAT HELPS
