Saab Key Programmingsaab 900 key cars manufactured from 1994 have an immobilizer that relies on coded keys. A new transponder is required for inclusion of an additional key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The problem is that this could be quite costly. This is why you should always have a spare key at hand.
Transponder key
The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is placed in the ignition. The car checks to see whether the signal matches the one on the key. If the signals are the same it will open itself and begin. This is a great method to avoid auto theft and keep your car secure from thieves.
Transponder keys are an increasingly popular feature in vehicles, but you should be aware that they aren't as secure as classic keys made of metal. While the metal component of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code that is inserted into a car's computers in order to identify it.
When a saab key fob (

It's important to make sure that you have an extra key for your Saab. This is especially important especially if you reside in a rural area, where there are a lot of car thieves. You can purchase a new key for your Saab by visiting the dealership, without having to pay their pricey costs. You can get an original key made on the spot for less than half what you would pay at dealerships.
Key for Wired
saab key battery replacement cars are typically delivered with two keys. If you own only one, you should get an additional key as quickly as you can. This is because if the key is lost and the car needs a new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.
The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. It's not a standard way to go about it, but you need to consider how you will route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After the rows and column are soldered together It is now time to connect the key switches. To do this, place a diode over each key switch pin and solder it. This will shield the pins from current and prevent them from being cut off. A diode permits current to only flow in only one direction. It is equipped with a visible indicator with a black band that shows the direction in which the current will flow.
Sanabria says that a few of the tools offered in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 will assist shoppers or DIY users to program replacement keys and restore immobilizer information. The tools plug into OBD ports and help the customer through each step, making the process easier than replacing the car's computer.
Jump starting the battery
The majority of people have a set of jumper cables in their trunk for emergency situations, but jumping a battery in newer cars might not be the best choice. These cars are equipped with a variety of computers and digital devices which communicate with each other. A surge in voltage when the battery is connected to another could cause damage to these components, rendering your car undriveable.
Start the vehicle you are using and allow it to run for approximately two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of your disabled car. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline in the engine compartment.
Once the cables are connected, turn on the vehicle you are not using and let it run for about five minutes before you disconnect them in reverse order. Be aware that the battery in your Saab 9-3 is recharged during your drive, which means it may take some time for the battery to go back to its original level. You should purchase an additional key fob as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.
replacement saab car keys Case
Many Saab owners only have one key for their vehicle and if they lose that key, it will cost them. It's costly to add a key and requires replacing the CIM or TWICE for older models. It is recommended to have a second key in case of theft or any other catastrophe, and the best way is to purchase a second key as soon as you are able to. Even if the key is "new", it will not function.
The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without the need to replace the entire system. This can save you lots of money. It's more affordable rather than wait until you lose the only key.
