saab 9-3 key Key Programming

Saab ignition key cars that were built prior to 1994 feature an immobilizer mechanism built on coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. This is why it is important to always have a spare key at hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is inserted into ignition. The car will then check the signal to determine whether it is identical to the one that is in the key. If the signals are in sync, the car will open and start. This is a fantastic way to protect your vehicle from theft.

Transponder keys could be an increasingly popular feature for cars, but they are not as secure as traditional metal keys. The metal part of the traditional key can be easily cut or copied, while transponders are protected by an electronic chip that protects it. This chip contains an individual code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. However, it can only do this if the fob is unmodified and has a chip that has been programmed to match it. Otherwise, the car will reject the key and not start.

It is essential to ensure that you have a spare key for your Saab. This is particularly important especially if you live in a rural region that has numerous car thieves. The good news is that it's possible to obtain a replacement key for your Saab without having to go to an auto dealership and pay the expensive prices that they ask. In most instances, you can get an original key made on the spot for less than half the price of what you would pay at an auto dealer.

Key for Wired

Saab cars are usually provided with two keys. If you have only one, it is recommended to purchase an additional key fob as quickly as you can in case you lose it, the car will require a new CIM unit, and the locking cylinders will need to be replaced. This could be expensive especially if you're buying a second-hand car.

The next step is to connect the wires for the column and row to the microcontroller. This is the most tedious part of the project, and will require a lot of soldering. There is no standard method to accomplish this, however it is important to think about the way you'll route and solder the rows and columns. There are 22 microcontroller wires and pins to connect for this keyboard. It has five rows and 17 columns.

After the columns and rows are joined after which it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and also prevent them from being shorted. A diode allows the flow of current to be in one direction, and it comes with a an indicator of black color that shows the direction in which current will flow.

Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY customers in certain cases replace keys in the program and saab ignition key restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the customer through each step which makes the process much easier than replacing the car's computer.

Jumpstarting the battery

The majority of people have a set of jumper cables in their trunk to use in an emergency, but jumping a battery for newer vehicles might not be the best option. They have numerous electronic devices and computers that communicate with each other. A voltage spike when the battery is connected to another battery could fry these components and render your car unable to drive.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). 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. Do not connect the black cable to the negative terminal on the dead battery because it could spark a spark that ignites the gasoline in the engine bay.

After the cables have been connected, begin the car and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It may take a while it to recharge again. You should purchase an additional key fob as soon as possible. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose it, it's going to cost them. It's expensive to add the key and also requires replacing the CIM or TWICE in the case of older models. It is best to have a backup key in case of theft or other disaster the best solution is to buy an extra key as early as you can. Don't buy a secondhand key, even if it's "new." Claimed-new keys purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.

The dealer will charge you top dollar if you have only one working key. We can, however, reset and re-program your computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This could save you lots of money. It's also a lot cheaper than waiting until you lose your one key.
