Saab cars made since 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required for addition of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

It can be costly. You should always keep a spare set of keys in your possession.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. The car checks to see whether the signal matches with the one on the key. If the signals are the same the car will then unlock itself and begin. This is a fantastic way to safeguard your car from theft.

Transponder keys may be an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. The metal component of a traditional key is easily cut and copied, whereas transponders are protected by an electronic chip that protects it. The chip has a unique code that is inserted into the car's computer in order to identify it.

When a saab 9-3 key key fob is used the car recognizes it and allows it to turn on. However, it can only do this if your key fob is unmodified and has a chip that has been programmed to match the original. The car will not start in the event that the key is not programmed to match.

It is essential to ensure that you have a spare key for your saab 9-5 key replacement. This is especially true especially if you reside in a rural area where there are numerous car thieves. You can obtain a replacement key for your saab key code by visiting the dealership, without having to pay their high prices. In most cases, you can have a new key made on-the-spot at a fraction of the cost you'd pay at dealerships.

Wired key

Saab cars are usually provided with two keys. If you only have one, it is recommended to purchase an extra key fob as soon as possible since if you lose it, your car will require an entirely new CIM unit and the locking cylinders will need to be replaced. This can be costly, especially for used cars.

The next step is to connect the wires for columns and row to your microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There is no standard method to do this, but it is essential to determine the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins from current, preventing them from being shortened. A diode permits current to only flow in one direction. It comes with a visual indicator, a black band, that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY customers in certain cases programme replacement keys and recover lost immobilizer data, Sanabria says. The tools connect to the OBD port and guide the user 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 for emergencies, but jumping a battery on newer vehicles may not be the most efficient option. These vehicles have many digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another can fry these components and render your vehicle undriveable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood--the engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks that could ignite the gasoline that is in the engine compartment.

Once the cables are connected, turn on the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge as you drive. It may take a while it to return to its original state. It's 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 it that your missing keys are not trying to steal the car.

Replacement Case

Many Saab owners have only one key for their vehicle and if they lose that the cost will be. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster the best solution is to purchase an additional key as soon as you can. Don't purchase a used key even it's "new." Claimed-new keys from aftermarket sellers will not work and are almost guaranteed to fail at the critical moment.

Most locksmiths aren't able to help if you have only one working key, and the dealer will charge you high fees to replace the computer in your car to make a replacement. However, we can reset and re-program your computer's EEPROM in order to prepare it to accept an alternative key without replacing the whole system. This can save you a great deal of money. It's also much less expensive than waiting until you lose the only key.
