if only to renew passport, just take her and bring the passport , to the indonesian embassy would do.

find out the address of the embassy online.

if work permit also need to renew . after the passport is done, then find out or google "malaysia work permit", should be the immigration department thing

never experience but heard a lot of friends mention, you will see many people , mostly those agent's runners, "cut Q" or get their things done faster than you although u have been there for 1whole day...and when processing & waiting in the embassy, imagine those amount of indon construction workers and others indon immigrants we have here in whole malaysia has to get it done in KL the embassy.

it is tedious, that's why those agents earn big bucks.
