Hi I have bmw x5 2003 e53,

I had problem with the external door handle carrier and while I was replacing that, I had a stripped wire from lock actuator that contacted the door panel,
it was one of the the lock actutator wire that was twisted together by stupid me 6 years ago in a repair. but I only was using electrical tape... anyways.

after that replaced the door handle carrier I noticed, lock actutator doesnt work anymore.

my scanner was showing something about "Cricut overload Lead" I realized maybe because wire contacted the door metal, it fried the lock actuator. so I got another one from junkyard and it still doesnt work

I also checked all the fuses for central locking system in the glove back and the trunk.

my autophix scanner shows two error codes A2 and 46 for
"ZKE Central Body Electronic”

without having any description what it is, Gemini AI says

46: This code likely points to a voltage supply issue to the ZKE module.
A2: This code could indicate a general electrical fault within the ZKE system.

could this possibly mean I ruined the GM module ? if yes, if I buy GM module from junkyard can I just simply replace it or do I need a special something to configure it?

my 12V battery is Old but it reads on 11.5V (when not running) but I dont think if that is the problem becasue other Lock acutators work (other than driver side)

please help me

(btw I got some butt connectors and I also got new harness and wire for the lock actuator from junkyards, this time I am doing it correctly not using eletrical tape)

Ps the windows act weird (passenger window open with delay) could that be gm module?
