Why We Why We Saab Ignition Key Replacement (And You Should Too!)

Saab Key Programming

Saab cars manufactured since 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

This can be expensive. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder can be described as a key equipped with an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car checks to see whether the signal matches with the one on the key. If the signals match then the car will be able to unlock and start. This is a fantastic way to safeguard your car from theft.

Transponder keys are a popular feature in automobiles, but it is important to know that they're not as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and copied the transponder is protected by an electronic chip. The chip has an unique code that is programmed into the car's computers to identify it.

When a saab key battery replacement key fob is used the car recognizes it and allows it to turn on. However, it can only do this if the key fob has a non-modified chip that has been programmed to match it. The car won't start when the key isn't programmed to match.

It is essential to ensure that you have a spare key for your Saab. This is especially true when you live in a rural area, where there are a lot of car thieves. The good part is that you can find a new key for your Saab without needing to visit a dealer and pay the expensive prices they ask. In most cases, you can have an original key made on the spot for less than half the cost of what you would pay at a dealer.

Key for Wired

Saab cars are usually provided with two keys. If you have only one, it is a good idea to get an extra key fob as soon as is possible since if you lose it, the car will require an entirely new CIM unit and the locking cylinders need to be replaced. This can be expensive especially for cars that are used.

The next step is to wire the wires of the column and row to the microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a common way to go about it, however, you should plan how to connect and solder each column and row. There are 22 microcontroller wires and pins to connect to this keyboard. It has 5 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 a diode across each pin on the key switch and then solder it. This will protect the pins from current, and prevent them from getting shorted. A diode only allows current to flow in one direction, and it also has a the black band as a visual indicator that shows the direction in which current will flow.

Sanabria says that a few of the tools sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 will assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to 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

The majority of people have an assortment of tools in their trunk to jump start a car in case of emergency, however it might not be a good idea for newer cars. These cars have a variety of computers and digital devices that communicate with one another. A surge in voltage when batteries are connected to another can fry the components and render your vehicle unusable.

Start the vehicle you are using and let it run for about two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the battery that is good. (It will say "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 ideal choice. Do not connect the black cable to the negative terminal of the dead battery as it could spark an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. Be aware that the battery in your Saab 9-3 is recharged while you drive, so it can take a while to get the battery back down again. It's a good idea buy a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and special programming to convince the system that your Lost saab Keys keys aren't in the process of trying to steal the car.

Replacement case

Many saab key battery replacement owners only have one key for their car and if they lose it, they'll be charged. The reason is that it's costly to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is recommended to have a second key in case of theft or any other catastrophe and the best option is to purchase a second key as quickly as you can. Don't buy a secondhand key even if it's "new." Keys that are claimed to be new from a second-hand store will not work and are likely to fail at the critical moment.

The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without having to replace the entire system. This could save you a lot of money. It's more affordable instead of waiting until you lose your only key.
