Saab Key Programmingsaab 93 key replacement cars manufactured from 1994 have an immobilizer system that relies on a set of keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
It can be costly. It is always advisable to keep a spare set of keys at hand.
Transponder key
The transponder can be described as a key with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then analyzes the signal to determine whether it is the same as the one on the key. If the signals match it will open itself and begin. This is a great method to safeguard your car from theft.
Transponder keys could be a popular addition to automobiles, but they are not as safe as traditional metal keys. The metal portion of a traditional key can be easily cut or copied, while the transponder is protected by an electronic chip that protects it. This chip has an individual code that is embedded into the car's computer to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. However, it will only do this if the fob has an unmodified chip that has been programmed to match it. Otherwise, the car will reject the key and not start.
It is essential to ensure that you have an extra key for your
saab key programming. This is particularly important for those who live in a rural area that is home to many car thieves. You can get a brand new key for your Saab by visiting the dealership and not paying their expensive prices. You can have the
replacement saab 9-3 key key on the spot at a fraction of what you would spend at a dealership.
Wired key
Saab cars usually come with two keys when new. If you only own one, you should get an extra key as soon as you can. This is because, if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used vehicle.
The next step is to wire the wires for the column and row to the microcontroller. This is the most laborious component of the project and it will require lots of soldering. There is no standard method to do this, but it's important to plan out
how to get a saab replacement key you will 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.
Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode over each pin of the key switch and solder it. This will protect the key switch pins from current and stop them from being shorted. The diode allows current to only flow in one direction. It has a visual indicator with a black band that indicates the direction in which current will flow.
Sanabria states that some of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY users to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the user through the process, making it more simple than replacing the computer in the vehicle.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunk in case of emergency, but jumping a battery on modern vehicles may not be the best option. These cars are equipped with a variety of computers and digital devices which communicate with one another. A surge in voltage while a battery is hooked up to another could cause damage to these components and leave your car unable to drive.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block is an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline in the engine compartment.
Once the cables are connected the vehicle you are not using and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 will be recharged while you drive. It will take a while for it to drop back down. It is a good idea to invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your lost keys are not trying to steal the car.
Replacement Case
Saab owners usually only have one car key, and if that is lost, they will be charged. The reason is that it's not inexpensive to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's best to have a spare key in the event of theft or any other catastrophe, and the best way is to purchase an extra key as soon as you can. Don't purchase a used key, even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't perform and are almost certain to fail at the critical moment.
The dealer will charge the highest dollars if you only have one working key. However, we can reset and re-program your computer's EEPROM to accept a new key without replacing the whole system. This can help you save money. It's much cheaper than wait until you lose the sole key.
