5 Things That Everyone Is Misinformed About Concerning Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since about 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required in order to enable the addition of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
It can be costly. This is why you should always have a spare key available.
Transponder key
The transponder key is a key equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are in sync the car will then unlock and begin. This is a great method to avoid car theft and keep your car safe from thieves.
Transponder keys are a common feature in automobiles, however you must be aware that they aren't as secure as classic keys made of metal. The metal part of the traditional key is easily cut or copied, while transponders are protected by an electronic chip which protects it. The chip is equipped with an individual code that is programmed into the car's computer to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do this if the fob has an unmodified chip that has been programmed to match it. If not, the car will reject the key and won't start.

There is no standardized way to accomplish this, but it is essential to determine the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
After the rows and column are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and also prevent them from being shorted. A diode allows the current to flow in a single direction, and has a an indicator in black that indicates the direction in which current will flow.
Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to OBD ports and help the customer through each step and make the process more straightforward than replacing the vehicle's computer.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunk in case of emergency however, jumping a battery on modern vehicles may not be the best idea.

Do not connect the black cable to the negative terminal on the dead battery because it could ignite a spark that ignites the gasoline in the engine bay.
After the cables have been connected, you should start the car and let it run for about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will be recharged as you drive. It will take some time for it to return to its original state. It is a good idea to purchase a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and a special program to convince the system that your lost keys are not trying to steal the car.
Replacement Case
Many Saab owners have only one key for their car and if they lose it, key, it will cost them. The reason is that it's costly to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a spare key in case of theft or any other catastrophe and the best option is to buy an extra key as quickly as you can. Don't purchase a used key, even it's "new."
