Saab Key Programming

Saab cars manufactured since 1994 have an immobilizer feature built on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be extremely expensive. It is always advisable to keep a spare set of keys available.

Transponder key

The transponder can be described as a key that has an electronic chip. The chip sends a signal when the key is put in the ignition. The car then checks the signal to determine whether it is the same as the one on the key. If both signals match the car will be able to unlock itself and start. This is a great method to safeguard your car from theft.

Transponder keys are an increasingly popular feature in automobiles, however you must be aware that they aren't as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip contains a unique code embedded into the car's computer to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and refuse to start.

Key for Wired

saab car keys cars typically come with two keys when they're new. If you own only one, you should purchase an extra key as soon as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly particularly if you are purchasing a used vehicle.

The next step is to connect the wires of the column and row to the microcontroller. This is the most tedious aspect of the project and will require lots of soldering. It's not a common way to do it, however, you should determine how to connect and solder 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 columns and rows are soldered, it's the time to connect them to key switches. To do this, place an inverter over each pin on the key switch and solder it. This will shield the pins from current and prevent them from getting shorted. A diode lets current only flow in one direction. It has a visual indicator, a black band, that shows the direction in which the current will flow.

Sanabria says that a few of the tools that are sold in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 can assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools connect to the OBD port and automatically guide the user through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

Most people keep a few sets of jumper cables in their trunks for emergency situations, but jumping a battery for newer vehicles might not be the best option. These vehicles are equipped with many digital and computers that communicate with each other. A voltage surge when a battery is connected to another battery could damage the components making your car inoperable.

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

After the cables have been connected, you need to start the vehicle and allow it to run for around five minutes. Then disconnect the cables in reverse. The battery in your saab key fob programming 9-3 will be recharged as you drive. It may take a while it to recharge again. It's a good idea buy a spare key fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and special programming to convince it that your lost keys aren't in the process of trying to steal the car.

Replacement case

Many saab key fob programming owners have only one key for their car and if they lose it, it's going to cost them. The reason for this is that it's expensive to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's recommended to have a backup key in the event of theft or any other catastrophe, and the best way is to purchase a second key as soon as you are able to. 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 create a replacement. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept the new key, without replacing the entire system. This can help you save a significant amount of money. It's also a lot cheaper than waiting until you lose your one key.
