Saab Key Programming

saab ignition key cars manufactured since 1994 use an immobilizer that relies on coded keys. A new transponder is required in order to enable the inclusion of an additional key, and special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

This can be expensive. Always keep an extra set of keys in your possession.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip sends a signal when the key is put in the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals are identical, the car will unlock itself and begin. This is a great method to stop car theft and keep your car secure from thieves.

Transponder keys are a common feature in automobiles, however you should be aware they are not as secure as classic keys made of metal. While the metal portion of a traditional key could be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code which is programmed into a car's computer in order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it is only able to do so if the key fob is equipped with a chip that is not modified that has been programmed to match it. Otherwise, the car will reject the key and refuse to start.

It's essential to ensure that you have a spare key for your Saab 9-3 Key Programming. This is especially true if you live in a rural location where there are numerous car thieves. The good news is that you can get a replacement key for your Saab without having to go to a dealer and pay the expensive prices that they demand. In the majority of instances, you can get a new key made on-the-spot at a fraction of the price of what you'd pay at the dealer.

Wired key

Saab cars are usually delivered with two keys. If you only have one, it's recommended to purchase an additional key fob as soon as is possible in case you lose it, your car will require an entirely new CIM unit, and the locking cylinders need to be replaced. This can be expensive, especially for used cars.

The next step is to wire the column and row wires to the microcontroller. This is the most difficult part of the project and will require a large deal of soldering. There is no standard method to do this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins that are used for key switches from current and keep them from being shorted. A diode allows current to only flow in one direction. It has a visual indicator with a black band that shows which way current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in some cases programme replacement keys and recover lost immobilizer data Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep a set in their trunks to jump-start a vehicle in an emergency, but it might not be the best idea for newer cars. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A surge in voltage when the battery is connected another one could cause damage to the parts making your car inoperable.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled vehicle's hood. An engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite the gasoline in the engine compartment.

After the cables have been connected, you can start the vehicle and let it run for approximately five minutes. Then disconnect the cables in reverse. Be aware that the battery in your Saab 9-3 is charged during your drive, which means it may take some time for the battery to come back to its original level. You should invest in another key fob as soon as possible. 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 it is lost, they will be charged. The reason for this is that it's costly to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other calamity it is recommended to have a spare key. Even when the key is "new" it will not function.

The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a replacement key without replacing the entire system. This can help you save money. It's also much less expensive than waiting until you lose the only key.
