Hello. Thanks for the donation. Much appreciated

Try resynching the keyfob (remote) this is usually the simple solution when battery has been disconnected?

STANDARD PROCEDURE - TRANSMITTER SYNCHRONIZATION
The following conditions can cause a transmitter and module to be out of synchronization:
Depressing a transmitter button while disconnecting the vehicle battery or power to the Body Control Module (BCM)
Pressing both transmitter for five seconds or longer when out of range of the vehicle
Pressing the transmitter button more than 255 times when out of range of the vehicle
Disassembling the transmitter, followed by reassembling it and pressing the transmitter buttons more than 10 times when out of range of the vehicle.
The transmitter and module can be synchronized by holding both the LOCK and UNLOCK buttons down for a period of 5 to 10 seconds. The module will acknowledge a successful synchronization by commanding a horn chirp. Normal transmitter function will return.
