Saab Key Programming

Saab cars made from 1994 have an immobilizer system that is based on key codes. A new transponder is required for the addition of an extra key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that this can be extremely expensive. This is why you should always keep a spare key in your possession.

Transponder key

The transponder key comes with an electronic chip that sends a signal to the car when it is inserted into the ignition. The car will then check the signal to determine whether it is identical to the one on the key. If the signals are in sync it will open and start. This is a great method to stop auto theft and keep your car secure from thieves.

Transponder keys are an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. The metal part of the traditional key can be easily copied and cut, but the transponder is protected by an electronic chip that safeguards it. The chip has a unique code that is programmed into the car's computers to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. Otherwise, the car would reject the key and not start.

It is crucial to have an extra saab 9 3 key replacement key. This is particularly true for those who live in a rural area that is home to numerous car thieves. The good news is that it's possible to find a new key for your saab 93 key without needing to visit a dealership and pay the expensive prices that they charge. You can have an original key made on the spot at a fraction of the cost you would pay at a dealership.

Key for Wired

Saab cars are usually delivered with two keys. If you only own one, it is recommended to get an additional key as quickly as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be costly, especially for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There is no standard method to accomplish this, but it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are 5 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 on each key switch pin. This will shield the pins on the key switch from current and stop them from being shorted. The diode allows current to only flow in one direction. It features a visual indicator of a black line that indicates which direction current will flow.

Sanabria states that a number of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep an assortment of tools in their trunks to start a car in case of emergency, however it might not be a good option for vehicles with newer technology. These cars are equipped with a variety of computers and digital devices which communicate with one another. A surge in voltage when a battery is hooked up to another battery could fry these components, rendering your car unable to drive.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged vehicle's hood. An engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery as this could cause an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, turn on the disabled vehicle and allow it to run for around five minutes before you disconnect the cables in reverse order. The battery in your saab spare key 9-3 will be recharged while you drive. It will take some time for it to drop back down. It's a good idea to buy a spare key fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and a special program to convince it that your missing keys aren't trying to steal the car.

Replacement case

Saab owners usually only have one car key, and if that is lost, they'll be charged. It's expensive to buy a key and requires replacing the CIM or TWICE for older models. In the event of theft or any other catastrophe it is advisable to have an extra key. But don't buy a used key, even the case that it's "new." Keys that are claimed-new from aftermarket sellers will not work and are likely how to program saab 9-3 key fob fail in the crucial moment.

The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and re-program your computer's EEPROM to accept a new key without replacing the whole system. This can help you save a significant amount of money. It's cheaper to do this rather than wait until you loose the only key.
