Saab Key Programming

saab keys cars manufactured since 1994 have an immobilizer system built on coded keys. A new transponder is required for the addition of a second key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The issue is that this could be extremely expensive. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder is a type of key with an electronic chip. The chip sends a signal when the key is put in the ignition. The car checks to see whether the signal matches the one on the key. If both signals match the car will be able to unlock itself and begin. This is a great method to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in automobiles, but it is important to know that they're not as secure as classic keys made of metal. The metal portion of a traditional key can easily be cut and copied, whereas the transponder is protected by an electronic chip that safeguards it. The chip has an unique code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob and allow it to turn on. The car can only recognize the key fob if it is equipped with an unmodified chip and programmed to match. The car will not start in the event that the key has not been programmed to match.

It is important to have an extra Saab key. This is especially important for those who live in a rural area where there are a lot of car burglars. The good part is that you can find a replacement key to your Saab without needing to visit a dealer and pay the expensive prices that they charge. You can have an original key made on the spot for less than half of what you would spend at dealerships.

Wired key

Saab cars are typically delivered with two keys. If you have only one, it's recommended to purchase an extra key fob as quickly as you can since if you lose it the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be expensive especially for used vehicles.

The next step is to wire the row and column wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard way to accomplish this, however it's important to plan out the route you'll take and solder the rows and columns. 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 soldered, it's the time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and stop them from being shorted. A diode allows current to only flow in only one direction. It has a visual indicator of a black line that shows the direction in which the current will flow.

Sanabria says that a few of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508, can help shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and help the customer through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

The majority of people have a set in their trunk to jump start a car in an emergency, but it might not be the best idea for vehicles that are newer. These cars are equipped with a variety of computers and digital devices which communicate with one another. A surge of voltage when the battery is connected another can fry the components making your car unusable.

Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the battery that is not working. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the affected car. The engine block is a great alternative. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline in the engine compartment.

Once the cables are connected, start the vehicle you are not using and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery in your saab 9-3 key not accepted contact service 9-3 is charged during your drive, which means it could take a while for the battery to go back to its original level. It is recommended to purchase a second key fob, when you can. Replacing the one that works requires the installation and programming of a new computer chip.

Many Saab owners only have one key for their car and if they lose that the cost will be. The reason for this is that it's not cheap to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's recommended to have a second key in the event of theft or other disaster, and the best way is to purchase an extra key as soon as you can. However, don't purchase a secondhand key, even it's "new." Keys that are claimed as new from a second-hand store will not work and are likely to fail at the crucial moment.

The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to make it ready to accept a replacement key without the need to replace the entire system. This could save you lots of money. It's less expensive than wait until you loose the only key.
