Default Key stopped working

I wonder if anybody can explain and help to solve the issue. Saab 9-3 2001, my ignition key stopped working first stopped remotely opening the doors and today stopped starting the engine. On the display I can see the message "not correct key" or something similar. I have two other keys and they both work without any problem. I checked the battery and it shows full 3V charge. I clean transmitter with electrical connectors cleaner, replaced battery with completely new one and still no effect. As I said the other keys, which luckily i have, are working. So what is the explanation? Don't ask me why I need three keys. It can lead to divorce and breaking family...
Thanks a lot

Key uses battery ONLY for remote.
IMMO uses chip, chip do not need battery.
After battery replacement, you have to re-sync remote by pressing door open button several times next to car.
Unfortunately this will not re-sync IMMO and chip.

Best solution now is re-marry key with TECH2.

As I wrote in my original message original battery was OK. I just replaced it to be sure that it is not battery. Remote control is not working after performing re-sync few times. It still does not explain while IMMO stopped working? Am I correct?

By the way, this should be in the "Workshop" forum.....

The simplest explanation is that the module that holds the buttons is damaged.

As Mimmi said, there are two functions the module does:
  1. Has security transponder (built in, nothing to do with battery)
  2. Has remote transmitter (needs battery)
I have had the transmitter fail, but the transponder was still good.


The only way you can really find out what's going on is to hook up a Tech II diagnostic instrument. It can tell you if the security computer has "forgotten" about this one key, or whether it knows about it but the key is not working properly. There's nothing really else you can do; you have tried re-synching the remote by pressing it a bunch of times. (You can try some more, maybe it will help--but for the remote only, won't help KEY NOT ACCEPTED message.)


The security module does come out of the key--when you open it up to change the battery, giving the buttons a good push pops it all out. The good news is that a working module can be installed. The bad news is that:
  1. You need a security module (they are available for "free" in some junkyards, otherwise find one on-line)
  2. The module needs to be programmed to your car using Tech II (both the security transponder and the remote).

You could always press the trunk button I believe while the key is in the ignition this should tell you how many transponders and remotes are programmed in the TWICE. That might give you an idea about if the transponder chip has failed or if the TWICE has somehow forgotten one.

Thank you all,
Jakejm79, how exactly should I do it? Should I use not working key? And should I press the trunk button on the key or on the door?
I did replaced the key before (that is why I have 3 keys now) It cost me close to $100 just for module from ebay and programming at the Saab Service. Given that I havve to working key now I don't have to do it at least now. But obviously would like to know what happened and why.

Sorry trunk button on the remote/key and yes a working key.
If you had 3 keys and remotes but only showing 2 on the SID then it sounds like the TWICE has somehow forgotten about 1 set. I'd verify that both the 2 other keys and remotes work properly.

You will likely need a TechII (or someone with one) to reprogram the TWICE for all 3 keys/remotes. You will need all of them present when you do that.
