Saab Key Programming

Saab cars made from 1994 have an immobilizer system that relies on keys that are coded. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. Always keep an extra set of keys at hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It transmits a signal to the car when it is inserted into ignition. The car will then check the signal to see whether it matches the one that is in the key. If the signals are the same the car will be able to unlock itself and begin. This is a great way to protect your vehicle from theft.

Transponder keys are an extremely popular accessory for automobiles, but they are not as safe as traditional metal keys. While the metal component of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip has an individual code that is programmed into the car's computers to identify it.

The car will recognize the saab 93 key keyfob and allow it to turn on. However, it is only able to do this if your key fob is unmodified and has a chip that has been programmed to match the original. Otherwise, the car would refuse to accept the key and will not start.

Wired key

Saab cars are usually supplied with two keys. If you only own one, you need to purchase an additional key as fast as you can. This is because if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if buying a used car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. It's not a common way to go about it, but you should consider how you will connect and solder each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 columns.

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

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in certain cases create replacement keys 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 a few sets of jumper cables in their trunks for emergencies however, jumping a battery in newer vehicles may not be the best idea. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A voltage spike when the battery is connected another could cause damage to the components making your car inoperable.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clear, unpainted metal surface under the hood of the affected car. 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 a spark, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, start the vehicle that is disabled and let it run for approximately five minutes before disconnecting them in reverse order. Keep in mind that the battery on your Saab 9-3 is recharged when you drive, and it can take a while for the battery to come back to its original level. It's a good idea to invest in a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince the system that your lost keys are not trying to steal the car.

Replacement Case

Saab owners usually have only one car key, and if that is lost, they'll be charged. It's expensive to purchase the key and also requires 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 any other catastrophe and the most effective way is to purchase an additional key as soon as you can. But don't buy a used key even when it's "new." Keys that are claimed as new from aftermarket sellers will not be effective and are almost guaranteed to fail in the crucial moment.

Most locksmiths cannot help you if you have only one working key, and the dealer will charge you top dollar to replace the computer in your vehicle to make a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This could save you a significant amount of money. It's cheaper to do this instead of waiting until you lose your only key.
