saab key programming (such a good point)
saab car key cars built since about 1994 come with an immobilizer system built on coded keys. A new transponder is required for inclusion of an additional key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The issue is that it can be quite costly. This is the reason why you should always have a spare key on hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal to the car when it is inserted into ignition. The car checks to see whether the signal matches the one on the key. If the signals match, the car will open and start. This is a great method to deter car theft and keep your car secure from thieves.
Transponder keys are a popular feature in cars, but you should be aware they're not as secure as classic metal keys. The metal portion of a traditional keys can be easily cut and copied, however a transponder has an electronic chip that protects it. This chip has an unique code that is programmed into the car's computers to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the fob is equipped with a chip that is not modified that has been programmed to match the original. The car won't start in the event that the key has not been programmed to match.
It's essential to ensure that you have an extra key for your Saab. This is particularly important for those who live in a rural region where there are a lot of car thieves. The good part is that you can find a new key for your saab replacement key without having to go to an auto dealer and pay the high prices that they charge. You can have a replacement key made on the spot at a fraction of the price you'd pay at an auto dealer.
Wired key
Saab cars usually come with two keys when they are new. If you have only one, it's recommended to purchase an extra key fob as quickly as you can as if you lose it the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be costly, especially if you are purchasing a used vehicle.
The next step is to wire the column and row wires to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There is no standard method to do this, but it is essential to determine the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.
Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from being shortened. A diode only allows current to flow in one direction, and it comes with a the black band as a visual indicator that indicates the direction current will flow.
Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 can assist customers who are shopping or DIY customers how to get a saab replacement key program replacement keys and restore immobilizer information. The tools plug into OBD ports and guide the user 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 trunks in case of emergency, but jumping a battery on modern vehicles may not be the best choice. They have numerous computers and digital devices that communicate with one another. A surge in voltage when the battery is connected to another can fry these components, rendering your car unable to drive.
Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface under the hood of the damaged vehicle. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition spark that ignites the gasoline in the engine bay.
After the cables have been connected, you can start the vehicle and allow it to run for around five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It may take a while it to return to its original state. It's a good idea to buy a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your lost keys aren't attempting to steal the car.
replacement saab car keys Case
Many saab key fob programming owners only have one key for their vehicle and if they lose that the cost will be. The reason is that it's expensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is recommended to have a backup key in case of theft or other disaster and the best option is to purchase an additional key as soon as you can. Don't buy a secondhand key, even when it's "new." Claimed-new keys purchased from third-party sellers won't work and are likely to fail in the crucial moment.
The dealer will charge you top dollar if you have only one working key. We can, however, reset and re-program your computer's EEPROM to accept the new key, without replacing the whole system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose your only key.
