Saab Ignition Key Replacement (Www.Forum.Breedia.Com) Key Programming

Saab cars made since 1994 utilize an immobilizer system that relies on key codes. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The issue is that this could be very expensive. It is always advisable to keep a spare set of keys on hand.

Transponder key

The transponder key comes with an electronic chip that sends a signal to the car when it is placed in the ignition. The car then checks the signal to determine whether it is identical to the one in the key. If the signals are in sync the car will then open and start. This is a great way to guard your car against theft.

Transponder keys are an increasingly popular feature in automobiles, but you must be aware that they are not as secure as classic keys made of metal. The metal component of the traditional keys can be easily copied and cut, but transponders have an electronic chip that guards it. This chip has a unique code programmed into the car's computers 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 has been programmed to match. In the absence of that, the car will reject the key and refuse to start.

It is essential to have a spare Saab key. This is especially important especially if you live in a rural location that has many car thieves. The good part is that you can find a new key for your Saab without having to go to a dealership and pay the high prices that they charge. You can get an original key made on the spot for less than half the cost you would pay at dealerships.

Key for Wired

saab key code cars typically come with two keys upon purchase. If you own only one, you should get an additional key as fast as you can. This is because if the key is lost the car will require a new CIM and the locking cylinders replaced. This can be costly particularly for used cars.

The next step is to wire the wires of the column and row to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There's no standard way to do it, but you must consider how you will route and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.

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 of the key switch from current and also prevent them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator of a black line that shows which way current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in certain cases replace keys in the program and restore lost immobilizer data, Sanabria says. 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

Most people keep an item in their trunks to jump start a vehicle in an emergency, however it might not be the best idea for cars with more modern technology. These cars have a variety of digital and computer systems that communicate with each other. A surge in voltage when a battery is hooked up to another battery could fry these components, rendering your vehicle undriveable.

Start the vehicle you are using and let it run for about two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood--the engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery as this could cause an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, start the vehicle that is disabled and let it run for about five minutes before you disconnect them in reverse order. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to drop back down. It is a good idea to purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince the system that your lost keys aren't attempting to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose that it's going to cost them. The reason for this is that it's expensive to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a second key in case of theft or other disaster and the most effective way is to buy an extra key as soon as you can. Even when the key is "new", it won't work.

The dealer will charge the highest dollar for only one working key. However, we can reset and reprogram the computer's EEPROM to accept an alternative key without replacing the whole system. This could save you a lot of money. It's also much less expensive than waiting until you lose the only key.
