Saab Key Programming
Saab cars built since about 1994 have an immobilizer system built on coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
It can be costly. Always keep an extra set of keys at hand.
Transponder key
The transponder is a key that is equipped with an electronic chip. The chip sends a signal when the key is put into the ignition. The car is able to check whether the signal matches the one on the key. If the signals match, the car will unlock and begin. This is an excellent way to protect your vehicle from theft.
Transponder keys are a popular feature in automobiles, however you should be aware they are not as secure as traditional metal keys. The metal portion of a traditional key can be easily cut and copied, whereas a transponder has an electronic chip that guards it. lost saab key is equipped with a unique code programmed into the car's computers to identify it.
The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob if it has an unmodified chip and has been programmed to match. If not, the car will reject the key and not start.
It's essential to ensure that you have a spare key for your Saab. This is particularly important if you reside in a rural area that is home to many car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their expensive prices. You can get the replacement key on the spot for less than half the price you'd spend at dealerships.
Wired key
Saab cars are usually delivered with two keys. If you only own one, you need to purchase an additional key as soon as you can. This is because if the key is lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used vehicle.
The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and will require a good amount of soldering. There isn't a standard method to do it, however, you should plan how to route and connect each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 columns.
Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, thus preventing them from being shortened. A diode only allows the flow of current to be in one direction, and it has an indicator of black color that indicates the direction current will flow.
Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can help shop customers or even DIY customers in certain instances create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunk for emergency situations, but jumping a battery for newer vehicles may not be the best idea. These cars have a variety of computers and digital devices that communicate with each other. A surge in voltage while a battery is hooked up to another one could damage these components, rendering your car unable to drive.
Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. 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 trigger sparks, which could ignite the gasoline inside the engine compartment.
After the cables have been connected, you should start the vehicle and let it run for approximately five minutes. Then disconnect the cables in reverse. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to fall back. It is a good idea to buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming 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 that it's going to cost them. The reason for this is that it's not inexpensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other disaster it is best to have a spare key. Don't buy a secondhand key, even the case that it's "new." Keys that are claimed-new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.
Most locksmiths aren't able to help if you have only one working key and the dealer will charge high fees to replace the computer in your car for a replacement. However, we can reset and reprogram the computer's EEPROM to accept the new key without having to replace the whole system. This can help you save money. It's also a lot cheaper than waiting until you lose your one key.
