Volvo: 2000 s80 2.9 Keyless entry, main computer, warning lights

Question
Keyless entry works on all doors except door on drivers side. I have to manual lock it. Any ideas as to problem and cost to get repaired? Also security alarm does not work or you can barley hear it. Had main computer replaced some months ago, at that time the car had warning lights on for a couple of things including security alarm check. Also sunroof will not open. A previous expert addressed that concern. Thanks in advance!

Answer
Linda,
The door lock assembly is likely at fault a common problem. Depending on the labor rate where you are about $325.00.
If you cannot hear the alarm something might be wrong or covering the horn. You need to inspect and see if it is coved or in need of replacement.
