Saab Key Programming

Saab cars manufactured since 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 handled by the dealer using a Tech2 diagnostic tool.

The issue is that this can be very costly. Always keep a spare set of keys in your possession.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car will then check the signal to see whether it is identical to that of the key. If the signals are in sync the car will then unlock and begin. This is a great method to stop auto theft and keep your car secure from thieves.

Transponder keys are a favored feature in cars, but you should be aware they are not as secure as traditional keys made of metal. While the metal part of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. This chip contains an unique code that is encoded into the car's system 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 the device has a chip that is unmodified and programmed to match. If not, the car will reject the key and refuse to start.

It is vital to have an extra Saab key. This is particularly important for those who live in a rural area, where there are a lot of car thieves. You can get a brand new key for your Saab by going to the dealership without paying their high cost. You can have the replacement key on the spot for less than half the cost you would pay at an auto dealer.

Wired key

saab 9-3 key fob replacement cars usually come with two keys upon purchase. If you have only one, you need to purchase an additional key as quickly as you can. This is because, if it's lost, the car will need a new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.

The next step is to connect the wires of columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There is no standard method to do this, but it is crucial to plan 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 to connect.

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 cut off. A diode permits current to only flow in only one direction. It features a visual indicator that is black, that shows the direction in which the current will flow.

Sanabria says that some of the tools sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools connect to OBD ports and guide the user through each step and make the process more straightforward than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks for emergencies however, jumping a battery on newer vehicles may not be the best idea. These vehicles are equipped with a number of computers and digital devices that communicate with each other. A surge in voltage when the battery is connected to another can fry these components, rendering your vehicle unable to drive.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of your disabled vehicle. The engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery, since it could spark an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Remember that the battery on your Saab 9-3 is recharged during your drive, which means it may take some time to get the battery back to its original level. It is recommended to purchase another key fob when you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Saab owners usually only have one car key, and if that is lost, they'll be charged. The reason is that it's expensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other calamity it is recommended to have a spare key. Don't buy a secondhand key, even it's "new." Keys that are claimed as new purchased from third-party sellers won't work and are likely to fail in the most critical moment.

The dealer will charge you the most expensive dollars if you only have one working key. We can, however, reset and reprogram the computer's EEPROM to prepare it to accept a new key without replacing the whole system. This can save you a great deal of money. It's also much less expensive than waiting until you lose the only key.
