The car battery died and I had to recharge it overnight. The central locking works fine with the key but not with the remote. Everything else works fine (I think!). I cant find anything in the manual to reset the system, it just says to take the car to a Saab dealer which is not what I had in mind. All help gratefully received.
Try to press the Unlock key six (or more) times. It works on 9000, 9-3, 9-5...

Like a lot of SAAB components, the manufacturer has tried to make them as least attractive and susceptible to theft as possible - try fitting a stereo from one SAAB to an identical model - it won't work. It is a question of divorce and marriage.
The components (electronic ones) are married to the individual car. Your remote from another car would need to be de-prgrammed by a dealer with full SAAB diagnostic equipment (if it is possible to de-program the remote), before being married to your car. A 9-3 can have up to 3 or 4 keys (mine has two - there were three but it's a long story!) with different levels of access for the car. Without the donor car available to electronically divorce the donated remote I am not sure that they will work.
Also bear in mind that different overseas markets use different UHF frequencies for remotes for car locking systems and unless the remotes are a perfect match for your car they may never work.
Slide out the metal key insert from the remote and check the engraved code on the inside curve of your remote to see if the part number matches or comes close to the one from your original key.

Most likely you have a bad TWICE unit. it is located under the driver's seat, at a low point in the floor and often gets wet.

Saab's have very specific steps that you must follow when you change the batteries in your key fob. You might try these steps to re-sync your key fob to your security system....
If the battery has been changed outside the
car and the car is locked, proceed as follows:
1 Unlock the front left door with the traditional
key. If the car has a car alarm, this
will be tripped.
2 Open the door and insert the remote
control into the ignition switch. If the car
has a car alarm, this will be silenced.
The remote control and receiver unit are
now synchronized.

Usually answered in minutes!
Despite no written responses, somebody must have fixed it by the power of thought ! As if by magic, not long after I posted the question, the system suddenly decided to start working again. I can only assume that the electronics somehow recognised the key after a number of times decided to accept it.
