Saab Key Programming

Saab cars produced from 1994 have an immobilizer that relies on keys that are coded. A new transponder is required for 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 very expensive. Always keep a spare set of keys available.

Transponder key

The transponder key is a key equipped with an electronic chip. It transmits a signal to the car when it is put into the ignition. The car then examines the signal to see whether it matches the one in the key. If the signals match then the car will be able to unlock and start. This is a fantastic way to protect your vehicle from theft.

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

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if your key fob is equipped with a chip that is not modified that has been programmed to match. In the absence of that, the car will reject the key and won't start.

It's important to make sure that you have an extra key for your Saab car keys. This is particularly important if you reside in a rural location that has numerous car thieves. The good part is that you can find a replacement key to your Saab without needing to visit an auto dealer and pay the high prices that they demand. In most instances, you can get an original key made on the spot at a fraction of the price of what you would pay at the dealer.

Key for Wired

Saab cars typically come with two keys upon purchase. If you only have one, it is recommended to purchase an extra key fob as soon as possible in case 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 wires of the column and row to the microcontroller. This is the most tedious aspect of the project and will require a lot of soldering. There is no standardized way to accomplish this, however it's important to plan out the route you'll take and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 column.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this you must place an inverter over each key switch pin and solder it. This will protect the pins that are used for key switches from current and keep them from being shorted. The diode will only allow the current to flow in a single direction, and it comes with a an indicator in black that shows the direction in which current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO or IM508, can help customers shopping or DIY customers to program replacement keys and restore immobilizer information. The tools plug into the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set in their trunks to jump-start their car in case of emergency, but this might not be the best option for vehicles with newer technology. These cars have a variety of digital and electronic devices that communicate with one another. A surge in voltage when the battery is connected to another one could cause damage to the parts and render your vehicle unusable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface beneath the hood of the affected vehicle. The engine block is an excellent option. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite gasoline in the engine compartment.

Once the cables are connected the vehicle that has been disabled and let it run for approximately five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will recharge while you drive. It may take a while it to recharge again. You should purchase another key fob when you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose that key, it will cost them. It's expensive to purchase the key and also requires replacing the CIM or TWICE in the case of older models. It is recommended to have a backup key in case of theft or any other catastrophe and the best option is to purchase an extra key as quickly as you can. Even even if the key is "new", it won't work.

The majority of locksmiths won't be able to help if you have only one working key, and the dealer will charge you high prices to replace the computer in your car to make a new replacement. We can, however, reset and re-program your computer's EEPROM to accept an alternative key without replacing the whole system. This could save you a lot of money. It's more affordable rather than wait until you loose the only key.
