Hi all,
So I have a 00' 9-3. It has 2 Banana fobs and keys.
Only 1 banana fob is working now. I thought it was the battery in the non-working one - so I swapped in a new one - but no joy.
So I keep my working fob at home - and use the other fob - by only using the key in the door and no remote functions.
I used the working fob the other day - and it had that faint 'flat battery sound' when I used the remote, but I didn't get any SID message about it.


Questions: I recall an 'orange' battery in the Saab alarm unit in the car (not sure if it was 9-5 or 9-3). Is this the case for 9-3? Will I get a SID message that battery needs replacing - or is it only in the Key?

Also - if the working fob goes flat / or the Car battery is disconnected - what happens with the alarm?

To fix/check - I assume I will need both keys, fobs + car at the auto electrician who has a tech 2?

Both the 9-3 and the 9-5 have the same orange batteries (there are two of them) in the siren module in the wheel well. You'll get a Service Theft Alarm message on the SID if the batteries in the siren are low. I believe that you'll also get a message saying something like Replace Key Battery when the battery in your fob gets low.

I've had my car's battery die and nothing out of the ordinary happens when I pop the hood and hook a charger up to it, but then I've also had the alarm go off when doing that after the battery gets charged for a minute or two. Luckily I had the key in my pocket so I didn't tick off the neighbors too much. :) If the battery in your fob dies, it's no big deal. You can lock and unlock the car with the key, and I believe that that still arms and disarms the alarm on the 9-3.

A Tech 2 should help, but if it's a dying fob, it might not tell anyone much about that. If you're going to pay someone to hook up a Tech 2, you might want to pick up a used fob on eBay just in case, so if one of your old fobsis dead, they can pair up the new one.

Don't forget that the remote needs to be resynced whenever you replace the batteries.

The batteries in the alarm/siren unit have no impact on the remote unlocking/locking, they purely serve to sound the alarm if the main car battery is disconnected.

Good points - Thanks. When I changed the batteries before I did the Unlock/ Lock x 8 as per guidance. My car is going on a ship soon - so I want to ensure I can use it at the other end.
