When I got my Volvo 2002 s40 back from the body shop after an airbag replacement and dashboard replacement, the remote door unlocks do not work.

In the old system there was on the far right side of the dashboard and semi-spherical blinking red light. It seems gone now. The door locks are not operable remotely as before.

So is this hard to fix or replace?

Any help appreciated.
