you will need to check your central locking fuses. The bmw database shows fuses 9 24 27 48 49 52 60 67 71 in the glove box fuse panel as those to check, but you should also reference your own fuse card to double check.

.

if the fuses are good, then this means you have a failed general module which is the computer module that manages locking. This is a common issue. You can send it out for repair to https://www.bmwgm5.com/bmwgm5/ or replace it.

.

the general module is located behind the glove box as shown here: https://www.bmwgm5.com/GM5_Removal.htm
