Saab Key Programming

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

The problem is that this can be quite costly. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a type of key that is equipped with an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals match then the car will be able to unlock and start. This is a great way to deter auto theft and keep your vehicle secure from thieves.

Transponder keys could be an increasingly popular feature for cars, but they're not as safe as traditional metal keys. While the metal part of a traditional key can be cut and copied, a transponder is protected by an electronic chip. The chip is a unique code that's programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. But, it's only able to do this if the fob has an unmodified chip that has been programmed to match. The car will not start in the event that the key has not been programmed to match.

It is important to have an extra Saab key. This is particularly important if you live in a rural area, where there are many car thieves. The good thing is that you can find a replacement key to your Saab without needing to visit a dealer and pay the hefty prices they ask. You can get a replacement key created on the spot for less than half of the price you'd pay at dealerships.

Wired key

saab key Code cars are usually provided with two keys. If you only have one, it is recommended to get an extra key as soon as you can. This is because if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be expensive especially for saab Key Code cars that are used.

The next step is connecting the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. There's no standard way to accomplish this, however it is crucial to plan the way you'll route and solder the columns and rows. 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 time to connect them to the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and prevent them from being shorted. A diode only allows current to flow in one direction, and it has the black band as a visual indicator that indicates the direction current will flow.

Sanabria says that a few of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 will assist customers who are 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 procedure, making it simpler than replacing the computer in the vehicle.

Jumpstarting the battery

A lot of people keep a set of jumper cables in their trunks for emergencies, but jumping a battery on newer cars might not be the most efficient option. They have numerous computers and digital devices that communicate with each other. A surge in voltage when batteries are connected to another one could cause damage to the parts making your car unusable.

Start the vehicle you are using and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a great choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite gasoline in the engine compartment.

After the cables have been connected, start the vehicle and let it run for about five minutes. Then disconnect them in reverse. Be aware that the battery in your saab 9-3 replacement key 9-3 is charged when you drive, and it may take some time to get the battery back to normal. It is recommended to purchase an additional key fob as soon as you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Replacement case

Saab owners typically only have one car key, and if that is lost, they'll be charged. It's expensive to buy a key and requires replacing the CIM or TWICE for older models. It's recommended to have a backup 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 are able to. Even it's "new" it won't work.

The dealer will charge you top dollar for only one working key. We can, however, reset and reprogram the computer's EEPROM to accept the new key, without replacing the entire system. This could save you a great deal of money. It's also much less expensive than waiting until you lose your sole key.
