The Advanced Guide To Saab Ignition Key Replacement

Saab Key Programming

Saab cars built since 1994 utilize an immobilizer system that relies on keys that are coded. A new transponder is required to allow the addition of a second key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that it can be extremely expensive. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is put into the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and start. This is an excellent way to protect your car from theft.

Transponder keys are a popular feature in vehicles, but it is important to know that they are not as secure as traditional keys made of metal. The metal component of the traditional keys can be easily copied and cut, but a transponder has an electronic chip that safeguards it. The chip has an individual code that is programmed into the car's computer to identify it.

When a saab key fob replacement 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 programmed to match. In the absence of that, the car will reject the key and not start.

It's crucial to ensure that you have a spare key for your saab 9-3 key not accepted contact service. This is especially important for those who live in a rural area, where there are many car thieves. You can get a brand new key for your saab 9-3 replacement key by going to the dealership without paying their expensive costs. In the majority of instances, you can get a new key created on-the-spot for less than half the cost you'd pay at an auto dealer.

Wired key

Saab cars are usually supplied with two keys. If you only have one, it's recommended to purchase an extra key fob as quickly as you can as if you lose it, the car will require an entirely new CIM unit and the locking cylinders will need to be replaced. This could be expensive particularly if you are purchasing a used vehicle.

The next step is connecting the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There isn't a standard method to go about it, however, you should determine how to program saab 9-3 key fob to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined then it's time to connect the key switches. To do this, you need to place an inverter over each pin of the key switch and then solder it. This will shield the pins from current, thus preventing them from being shorted. A diode only allows the current to flow in a single direction, and it has the black band as a visual indicator that indicates which way the current will flow.

Sanabria states that a number of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 can assist customers shopping or DIY users to program replacement saab 9-3 key keys and restore the immobilizer's data. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set in their trunks to jump-start their vehicle in an emergency, but it might not be the best idea for cars with more modern technology. These vehicles have many computers and digital devices that communicate with one another. A voltage surge while the battery is connected to another one could damage the components and render your car unable to drive.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline in the engine compartment.

Once the cables are connected, start the vehicle that has been disabled and let it run for approximately five minutes before you disconnect them in reverse order. Be aware that the battery of the Saab 9-3 will be charged while you drive, so it may take some time for the battery to come back to its original level. You should 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

Many saab 9-3 Key fob programming owners only have one key for their car and if they lose that key, it will cost them. The reason for this is that it's expensive to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a spare key in the event of theft or other disaster, and the best way is to purchase an additional key as early as you can. But don't buy a used key even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't work and are almost guaranteed to fail in the most critical moment.

The dealer will charge the highest dollars if you only have one working key. We can reset and reprogram the EEEPROM of your computer for it to accept a replacement key without replacing the entire system. That can save you a significant amount of money. It's also less expensive than waiting until you lose your only key.
