Saab Key Programming

Saab cars produced from 1994 have an immobilizer system based on coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to the car when it is inserted into ignition. The car is able to check if the signal matches the one on the key. If the signals are identical, the car will unlock itself and start. This is a great method to guard your car against theft.

Transponder keys can be an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip is a unique code that's 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 can only recognize the key fob if the device has an unmodified chip and has been programmed to match. The car won't start if the key is not programmed to match.

It's important to make sure that you have a spare key for your Saab. This is particularly true for those who live in a rural area that is home to numerous car thieves. The good thing is that you can get a replacement key for your saab fob key replacement without needing to visit an auto dealer and pay the hefty prices that they charge. You can get an original key made on the spot for less than half of the cost you would pay at an auto dealer.

Key for Wired

Saab cars are usually provided with two keys. If you only have one, it's a good idea to get an additional key fob as soon as you can since if you lose it, your car will require a new CIM unit, and the locking cylinders need to be replaced. This could be expensive especially if you're purchasing a used car.

The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a large amount of soldering. It's not a common way to go about it, but you should consider how to open a saab 93 without a key you will route and connect each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It includes 5 rows and 17 column.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins from current, preventing them from getting shorted. A diode permits current to only flow in only one direction. It is equipped with a visible indicator of a black line that indicates which direction current will flow.

Sanabria states that some of the tools available 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 information. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep the set in their trunk to jump-start their vehicle in the event of an emergency, however it might not be a good option for vehicles with newer technology. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage spike when batteries are connected to another battery could damage the components, rendering your car undriveable.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface under the hood of the affected vehicle. The engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery as it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle and allow it to run for around five minutes. Then, disconnect them in reverse. Remember that the battery on your saab replacement key programming 9-3 is charged when you drive, so it can take a while for the battery to come back to normal. It is recommended to purchase a second key fob, when you can. Replacing the original 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 it is lost saab key, they will be charged. It's expensive to add keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft, or any other calamity it is recommended to have an extra key. But don't buy a used key, even if it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't work and are almost guaranteed to fail at the critical moment.

Most locksmiths aren't able to help when you only have one working key, and the dealer will charge high fees to replace the computer in your car to make a new replacement. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without replacing the entire system. This could save you a lot of money. It's cheaper to do this than waiting until you loose the only key.
