Hi
@gliu89 ,
Welcome to TMC !!!
Questions...
Did it work before battery died???
Does it work with the other fob???
If it works with the other fob, your battery replaced fob may be bad and need to be replaced...
Assuming it worked correctly at one time -
If it does not work with either fob your car needs a service call.
When this happened to mine (assuming all settings are correct)
the Central Body Controller may need to be replaced...
Good luck and again Welcome!!!
