Saab Key Programming

Saab cars made from 1994 have an immobilizer system based on keys that are coded. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that this could be very expensive. Always keep an extra set of keys on hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal back to the car when it is inserted into the ignition. The car then checks the signal to determine whether it is the same as that of the key. If the signals match the car will then unlock and start. This is a great method to prevent car theft and keep your car secure from thieves.

Transponder keys can be an extremely popular accessory for cars, but they are not as secure as traditional metal keys. While the metal component of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code that is programmed into the car's computer in order 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 is equipped with a chip that is unmodified and programmed to match. The car will not start when the key isn't programmed to match.

It is essential to ensure that you have a spare key for your Saab. This is especially important when you live in a rural area where there are numerous car thieves. The good part is that you can obtain a replacement key for your Saab Ignition Key without needing to visit a dealer and pay the expensive prices that they charge. In the majority of cases, you can have a new key created on-the-spot at a fraction of the cost you would pay at a dealer.

Wired key

Saab cars are typically delivered with two keys. If you only own one, you need to purchase an additional key as fast as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used vehicle.

The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There's no standard way to accomplish this, but it's important to plan out how to program saab 9-3 key fob 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.

After the rows and column are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and also prevent them from being shorted. A diode allows current to flow in one direction, and has a an indicator in black that indicates the direction current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may assist customers at the shop or DIY customers in certain instances programme replacement keys and recover the lost saab key immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunks for emergencies, but jumping a battery for newer automobiles might not be the best option. These vehicles have many electronic devices and computers that communicate with each other. A surge in voltage while a battery is hooked up to another can fry these components and leave your car unable to drive.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface underneath the hood of the affected car. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery because this could cause an ignition source that ignites gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run for about 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. You should invest in another key fob when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners often only have one car key, and if that is lost, they will be charged. The reason is that it's not inexpensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a spare key in the event of theft or any other catastrophe, and the best way is to buy an extra key as soon as you can. However, don't purchase a secondhand key, even the case that it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are likely to fail in the most critical moment.

Most locksmiths cannot help you if you have only one working key, and the dealer will charge you high prices to replace the computer in your car to make a new replacement. However, we can reset and re-program your computer's EEPROM to accept the new key without having to replace the whole system. This can save you a significant amount of money. It's less expensive rather than wait until you lose your only key.
