Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer system that is based on a set of keys. A new transponder is required for the addition of an additional key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that it can be extremely expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car is able to check if the signal matches the one on the key. If the signals match the car will then open and start. This is a great method to deter car theft and keep your car safe from thieves.

Transponder keys could be a popular addition to cars, but they are not as safe as traditional metal keys. While the metal component of a traditional key could be cut and copied, a transponder is protected by an electronic chip. The chip contains a unique code that is programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. The car will not start if the key is not programmed to match.

It's essential to ensure that you have a spare key for your Saab. This is particularly important if you live in a rural region where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership without paying expensive costs. You can get the replacement key on the spot at a fraction of the price you'd pay at the dealership.

Wired key

Saab cars are usually provided with two keys. If you have only one, you should purchase an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be expensive particularly for used cars.

The next step is to connect the wires of the column and row to the microcontroller. This is the toughest part of the project, and Lost Saab Key will require a lot of soldering. It's not a standard way to go about it, but you should think about how to route and solder each column and row. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 column.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this you must place a diode over each key switch pin and solder it. This will shield the pins from current and prevent them from being shorted. A diode allows current to only flow in only one direction. It features a visual indicator that is black, that indicates the direction in which current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY customers in certain cases replace keys in the program and restore lost saab key immobilizer data Sanabria says. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.

Jump-starting the battery

The majority of people have the set in their trunks to jump start a vehicle in an emergency, but this might not be a good idea for cars with more modern technology. They have numerous electronic devices and computers that communicate with each other. A voltage spike when batteries are connected to another battery could damage the components making your car inoperable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of your disabled vehicle. The engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, turn on the disabled vehicle and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge while you drive. It will take a while for it to return to its original state. You should consider purchasing a second key fob, when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their car and if they lose that it's going to cost them. The reason for lost Saab key this is that it's expensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other disaster it is recommended to have a spare key. But don't buy a used key, even it's "new." Keys that are claimed as new from a second-hand store will not work and are likely to fail in the most critical moment.

Most locksmiths cannot help you in the event that you only have one working key, and the dealer will charge for the cost of replacing the computer in your vehicle to create a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without having to replace the entire system. This can save you a lot of money. It's less expensive rather than wait until you loose the only key.
