Saab Key Programming
Saab ignition key replacement - telegra.ph, cars made since 1994 have an immobilizer feature made up of coded keys. A new transponder is required to allow the addition of a second key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.
It can be costly. This is why you should always keep a spare key in your possession.
Transponder key
The transponder is a type of key that has an electronic chip. This chip sends a signal when the key is put in the ignition. The car then checks the signal to see whether it is the same as the one on the key. If the signals are in sync then the car will be able to unlock and start. This is an excellent way to protect your vehicle from theft.
Transponder keys could be an increasingly popular feature for cars, but they are not as safe as traditional keys made of metal. While the metal part of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip has an individual code that is embedded into the car's computer to identify it.
The car will recognize the saab 9-3 key fob replacement keyfob, and allow it to turn on. But, it's only able to do this if your key fob is unmodified and has a chip that has been programmed to match the original. The car won't start if the key is not programmed to match.
It is essential to ensure that you have an extra key for your saab car key. This is especially important when you live in a rural area, where there are a lot of car burglars. The good news is that you can find a replacement key to your Saab without having to go to a dealer and pay the high prices that they demand. In the majority of cases, you can have a brand new key made right on the spot at a fraction of the price of what you would pay at the dealer.
Key for Wired
Saab cars typically come with two keys when they are new. If you only have one, it is a good idea to get an extra key fob as quickly as you can since if you lose it, the car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This can be expensive especially for cars that are used.
The next step is to wire the wires of the column and row to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There isn't a standard method to go about it, but you need to think about how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.
After the columns and rows are joined, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from getting shorted. The diode allows current to only flow in one direction. It is equipped with a visible indicator, a black band, that indicates which direction current will flow.
Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.
Jumpstarting the battery
Most people keep a few sets of jumper cables in their trunk for emergencies, but jumping a battery on modern vehicles might not be the best choice. These vehicles are equipped with digital and computer systems that communicate with each other. A surge in voltage while the battery is connected to another could cause damage to the components and render your car undriveable.
Start the vehicle that is working and let it run for about two minutes before connecting the cables to the one that is disabled. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled vehicle's hood. An engine block is a good option. Don't connect the black cable to the negative terminal on the dead battery because it could spark a spark that ignites the gasoline in the engine bay.
Once the cables are connected, begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. Remember that the battery on your Saab 9-3 is recharged when you drive, and it can take a while for the battery to come back to normal. 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 the lost keys are not trying to steal the car.
Replacement case
Many saab spare key owners only have one key for their vehicle and if they lose it, it's going to cost them. The reason for this is that it's not cheap to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other calamity it is recommended to have an extra key. However, don't purchase a secondhand key, even when it's "new." Keys that are claimed as new from aftermarket sellers will not work and are likely to fail at the crucial moment.
The dealer will charge the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement saab key key without the need to replace the entire system. This can help you save a significant amount of money. It's also much less expensive than waiting until you lose your only key.
