Saab Key Programming

Saab cars built from 1994 have an immobilizer that relies on keys that are coded. A new transponder is required for inclusion of an additional key, and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

This can be expensive. Always keep an extra set of keys in your possession.

Transponder key

The transponder is a type of key that is 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 matches the one that is in the key. If the signals are in sync the car will then open and start. This is a great way to deter car theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in vehicles, but you should be aware they are not as secure as classic keys made of metal. While the metal component of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip is equipped with an individual code that is embedded into the car's computer to identify it.

The car will recognize the saab key replacement bristol keyfob, and allow it to turn on. However, it will only do this if your key fob has an unmodified chip that has been programmed to match. In the absence of that, the car will reject the key and not start.

It is important to have a spare Saab Key Battery Replacement key. This is especially true especially if you live in a rural area with many car thieves. You can get a brand new key for your Saab by going to the dealership and not paying their high prices. You can have a replacement key created on the spot for less than half of the cost you would pay at the dealership.

Key for Wired

Saab cars are typically delivered with two keys. If you only own one, it is recommended to get an additional key as soon as you can. This is because if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This could be expensive particularly if you are buying a used car.

The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. It's not a standard way to go about it, but you need to consider how you will connect and solder each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 5 rows and 17 columns.

After the rows and column are joined, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being cut off. A diode only allows the current to flow in a single direction, and it comes with a an indicator of black color that shows the direction in which current will flow.

Sanabria states that a number of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 will assist customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunks in case of emergency however, jumping a battery for newer cars might not be the best idea. These vehicles are equipped with a number of digital and electronic devices that communicate with one another. A voltage spike when the battery is connected another could cause damage to the components and render your vehicle unusable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface beneath the hood of your disabled vehicle. The engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected the disabled vehicle and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will recharge as you drive. It will take some time for it to return to its original state. You should consider purchasing an additional key fob as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners typically only have one car key, and if it is lost, they will be charged. The reason is that it's expensive to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft, or other catastrophe it is advisable to have a spare key. Even if the key is "new", it will not work.

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