Saab Key Programming

Saab cars made since 1994 utilize an immobilizer that relies on coded keys. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that this can be extremely expensive. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car is able to check if the signal matches the one on the key. If the signals are the same the car will then unlock itself and start. This is a great method to protect your vehicle from theft.

Transponder keys may be a popular addition to cars, but they're not as secure as traditional keys made of metal. While the metal part of a conventional key can be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code that's programmed into a car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and refuse to start.

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 great deal of soldering. There isn't a standard method to do it, but you should think about how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

After the rows and column are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, preventing them from being shorted. A diode can only allow the flow of current to be in one direction, and it also has a the black band as a visual indicator that indicates which way the current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even DIY customers in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the customer through each step and make the process more straightforward than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery for newer automobiles might not be the best idea. These cars are equipped with a variety of digital and computers that communicate with each other. A voltage surge while a battery is hooked up to another could cause damage to these components, rendering your car undriveable.

Start the vehicle that is working and allow it to run for approximately two minutes before you connect the cables to the disabled one. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the disabled vehicle. The engine block is a good alternative. Don't connect the black cable to the negative terminal on the dead battery, as it could spark a spark that ignites the 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 them in reverse order. Be aware that the battery of the Saab ignition Key 9-3 gets recharged while you drive, so it could take a while to get the battery down.

The dealer will charge you the most expensive 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 replacing the entire system. This can save you a significant amount of money. It's cheaper to do this than wait until you lose the only key.
