Unlike the classic Saab keys of the past keys, the latest keys have electronic components which makes it hard to duplicate. This has made car theft considerably more difficult than it was years ago. However, it has also made replacing lost keys a much more expensive task.
Saab 9-3 owners should have two working keys. If one is lost, it costs a fortune to add another to the car, as it requires replacing the CIM module and programming the locking cylinders. Dealers usually charge between $100 and $200 for this.
There are options to avoid these costs. Some parts providers will use the code of a spare key to cut a brand new metal blade at a fraction what the dealer charges. The key must be the exact same as the original to allow it to work in your vehicle.
Follow these steps to replace the case. You'll require a flathead screwdriver as well as some patience. With the screwdriver, slowly pull the plastic apart and remove the emergency key from the case. When the case is opened take out all electronic components and place them in your new case. Make sure you insert the correct key and badge back into the case, as well.

Replacement Battery
The Saab 9-3 replacement battery is a cheap component that can be quickly and easily replaced. This YouTube DIY video Cyclone Cyd, a user on YouTube, explains how to replace the battery in the remote key fob in just four steps. This tutorial is compatible with any modern Saab key fob. However, the procedure could differ slightly.
The first step is to locate the button that will release the backup key within the fob. The button is usually found on the back of the fob close to the Saab Logo. Next take a flathead screwdriver to insert into the small hole of this button. This should be sufficient to open the fob case to allow you to change the battery.
After you have installed the new battery CR1632, you are able to rebuild the remote key fob. Then, you can program it into your car. The whole process should not take more than one hour. It's a simple process that doesn't require any special tools.
The process can be a bit more complex if you lose your key, but it is possible. The dealer must read the car's VIN and then order a new key blade and TWICE module, both with the correct unique code. The dealer will then have to program the key using MDI, a brand new software tool.
Replacement Key Fob
The key fob is the piece that locks and unlocks your car, it's got batteries inside. Batteries have a finite lifespan and eventually will die. This is a frequent issue in all vehicles. The good thing is that you can replace the battery in all key fobs, without having to replace the entire case. Amazon sells replacement fobs that have all the electronics in place. It is easy to pop the case open and replace the batteries. It is necessary to remove the emergency key before you can replace the batteries. To do this, insert the screwdriver of a small flat head into the slot that is in the middle. The case will split once you move the screwdriver around it.
If you are about to replace the keys ensure that you have a spare, as this can reduce the total cost by a substantial amount. If you have spare keys, you can request that the dealer cut an additional key and program it to your car, which is much cheaper than replacing the whole key fob.
It is possible to add a second key to your car even if you don't have one, but it takes an extensive amount of research and work. Adding a second key costs about a few hundred dollars and it also requires the programming of the car's computer. This can be accomplished by a professional, however it's a costly choice for most owners.
Replacement Ignition
The new SAAB 9-3 is a more sophisticated alarm system built on a keycode. This means that if you lose your only functioning key, getting another one could be very expensive since the car has to have a specific computer module installed, and it must also be programmed to accept an extra key. Locksmiths typically aren't able to program this or even dealers will charge hundred dollars just to program the new key!
Dealers will charge you a premium to replace your car's computer (also called the CIM or SAAB twice) in the event that you lose your sole working key. We can reprogram the current EEPROM in your car computer to make it ready for an additional key. This will save you more than 50% on the cost you would spend at a dealer.
If you've owned a SAAB 9-3 for an extended period of time you are aware that the ignition keys are not very durable. They can become extremely sticky and the buttons can be ripped off every now and then and you should think about buying a new one if the one you have isn't functioning properly. The good news is that replacing the ignition key isn't as difficult as it seems and is fairly easy to do with the proper tools.
