DIY Key Initialization Issues - Please Help!!

Hi All,

Hoping for some much needed guidance after lengthy searching online. Recently, since I had my battery replaced in my car (or around that time) my key battery also crapped out. So... I attempted the DIY fix of the battery. All disconnected and replaced, but no luck initializing the key. I've been trying to rule out many items over the past few weeks to no avail. Any tips you can provide I would greatly appreciate!!

Things I have done:
-Fuses - all look to be good.
-Fuel Filler Actuator - active when car is locked
-Central Module - All buttons on the interior are fully functioning (i.e. trunk, hazards, central locking)

Issues: Door actuator on drivers door is also faulty. Is this causing my issue with initializing the key?

What can I be missing?? Did I just not do a good job replacing the battery in the key?

Thanks so much for your time and guidance here.

If there are any issues with the central locking system (you mention the driver's door actuator)...this will 99% of the time create a failure in the remote keyless functions.

Fix the central locking system issue with the door actuator...then attempt to initialize the keys to bring back FZV/DWA remote functions.

Thanks for the prompt reply! I was afraid that was causing my problem.

Am I right to assume that the actuator is in fact the part that is broken? I am able to open the door manually with the key, but no functions are controlled from the interior buttons.

If so, I think I just found my weekend DIY project
