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

The problem is that it can be very costly. You should always keep an extra set of keys at hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is placed in the ignition. The car then examines the signal to determine whether it matches that of the key. If the signals are identical the car will be able to unlock itself and begin. This is a great method to protect your vehicle from theft.

Transponder keys are an increasingly popular feature for cars, but they're not as secure as traditional metal keys. The metal component of the traditional key is easily copied and cut, but a transponder has an electronic chip that guards it. The chip is equipped with a unique code that is embedded into the car's computer to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. However, it is only able to do this if your key fob has a non-modified chip that has been programmed to match. In the absence of that, the car will reject the key and refuse to start.

It's important to make sure that you have a spare key for your Saab. This is particularly important for those who live in a rural location where there are many car thieves. You can get a brand new key for your saab 9-3 key fob replacement by going to the dealership and not paying their pricey cost. In most instances, you can get a new key made on-the-spot for less than half the price of what you would pay at the dealer.

This is because, if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly particularly for used cars.

The next step is to connect the row and column wires to the microcontroller. This is the most tedious part of the project and will require lots of soldering. There's no standard way to do this, but it is important how to program saab 9-3 key fob think about the routes you'll use to solder the columns and rows. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 columns.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this, you need to place an inverter over each key switch pin and then solder it. This will protect the pins on the key switch from current and stop them from being shorted. The diode allows current to only flow in one direction. It has a visual indicator, a black band, [empty] that shows the direction in which the current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508, can help customers who are shopping or DIY users to program replacement keys and restore immobilizer information. 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

A lot of people keep an item in their trunk to jump-start a car in case of emergency, but it might not be a good idea for cars with more modern technology. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A voltage surge when the battery is connected to another can fry the components making your car inoperable.

Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block is an ideal choice. Don't connect the black cable to the negative terminal on the dead battery, as this could cause an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle you are not using and let it run for about five minutes before you disconnect the cables in reverse order. Remember that the battery on the Saab 9-3 will be charged while you drive, so it could take a while for the battery to go back to normal. You should consider purchasing a second key fob, when you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement case

Many saab key fob owners only have one key for their car and if they lose it, key, it will cost them. The reason is that it's not inexpensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or other catastrophe it is advisable to have a spare key. Don't buy a secondhand key even when it's "new." Keys that are claimed-new from aftermarket sellers will not be effective and are almost guaranteed to fail in the most critical moment.

The dealer will charge you the most expensive dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to make it ready to accept a new key without the need to replace the entire system. This could help you save a significant amount of money. It's more affordable instead of waiting until you lose the sole key.
