Saab Key Programming

saab 93 key replacement cars that were built prior to 1994 have an immobilizer system made up of coded keys. A new transponder is required to allow the inclusion of an additional key, and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The issue is that this can be very costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car will check to see whether the signal matches with the one on the key. If both signals match it will open itself and begin. This is a great way to prevent car theft and keep your vehicle safe from thieves.

Transponder keys are an increasingly popular feature in cars, but you should be aware that they are not as secure as traditional metal keys. The metal portion of a traditional keys can be easily copied and cut, but the transponder is protected by an electronic chip that guards it. This chip contains an unique code which is programmed into a car's computers in order 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 a chip that is unmodified and programmed to match. The car won't start in the event that the key has not been programmed to match.

It is important to have a spare Saab key. This is especially important for those who live in a rural region where there are a lot of car burglars. You can get a new key for your Saab by visiting the dealership, without having to pay their expensive cost. You can get a replacement key made on the spot at a fraction of the cost you would pay at an auto dealer.

Wired key

saab key battery cars are usually supplied with two keys. If you only have one, it is recommended to get 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 could be expensive particularly if you are buying a used car.

The next step is to connect the column and row wires to the microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There's no standard way to do it, but you need to consider how you will route and connect each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 columns.

After the rows and column are soldered together after which it is time to connect the key switches. To do this, you need to place a diode on each pin on the key switch and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. A diode permits current to only flow in only one direction. It features a visual indicator, a black band, that shows which way current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 will assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump starting the battery

The majority of people have an assortment of tools in their trunk to jump start a car in case of emergency, but this might not be a good option for vehicles with newer technology. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A surge of voltage when the battery is connected another one could cause damage to the parts making your car inoperable.

Connect the cables to the vehicle that is 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 the damaged vehicle. The engine block is a great option. The black cable is not to be connected to the negative terminal of the dead battery. This could create a spark, which would ignite the gasoline inside the engine compartment.

After the cables have been connected, start the vehicle and let it run about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will be recharged while you drive. It takes a while for it to drop back down. It's a good idea to purchase a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and special programming to convince it that your missing keys are not trying to steal the car.

Replacement Case

Saab owners typically only have one car key, and if that is lost, they'll be charged. It's costly to add a key and requires replacing the CIM or TWICE for older models. In the event of theft, or other catastrophe, it is best to have an extra key. Even it's "new" it won't work.

The dealer will charge the highest dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a new key without the need to replace the entire system. This could help you save a significant amount of money. It's cheaper to do this than wait until you lose the sole key.
