Indisputable Proof You Need Saab Ignition Key Replacement

Saab Key Programming

Saab cars made since 1994 come with an immobilizer system that is based on codes for keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

This can be expensive. Always keep an extra set of keys available.

Transponder key

The transponder key comes with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car will then check the signal to see if it matches that of the key. If the signals match the car will be able to unlock itself and start. This is a great method to stop car theft and keep your vehicle secure from thieves.

Transponder keys may be an extremely popular accessory for automobiles, but they are not as secure as traditional keys made of metal. While the metal component of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code that is inserted into a car's computer 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 this if the fob has a non-modified chip that has been 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 spare key. This is especially important when you live in a rural location that has many car thieves. The good part is that you can get a replacement key for your Saab without needing to visit an auto dealership and pay the high costs that they demand. You can get a replacement key made on the spot for less than half of the cost you would pay at an auto dealer.

Key for Wired

Saab cars usually come with two keys when they are new. If you have only one, it's recommended to purchase an extra key fob as soon as is possible, because if you lose it, your car will require a new CIM unit, and the locking cylinders need to be replaced. This can be costly especially for used vehicles.

The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There is no standardized way to do this, but it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are 5 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 the time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and stop them from being shorted. The diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that shows which way current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY customers in certain cases create replacement keys and restore the Lost Saab Key immobilizer's data, Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it simpler than replacing the computer in the vehicle.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunks for emergency situations however, jumping a battery on modern automobiles might not be the most efficient option. These vehicles have many electronic devices and computers that communicate with one another. A voltage surge while the battery is connected to another battery could fry these components and leave your car unable to drive.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (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 ideal choice. Don't connect the black cable to the negative terminal of the dead battery because this could cause an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should begin the car and allow it to run for around five minutes. Then disconnect them in reverse. Remember that the battery on the Saab 9-3 will be charged when you drive, so it may take some time for the battery to come back to normal. You should invest in a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Many lost saab keys owners only have one key for their vehicle and if they lose that the cost will be. The reason for this is that it's costly to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other calamity it is best to have a spare key. Even it's "new" it will not function.

The dealer will charge you top dollars if you only have one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This can save you a great deal of money. It's cheaper to do this instead of waiting until you lose the sole key.
