Saab cars manufactured from 1994 have an immobilizer system based on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that it can be quite costly. This is why it is important to always have a spare key on hand.

Transponder key

The transponder key is a key with an electronic chip that sends a signal to car when it is inserted into ignition. The car then checks the signal to see whether it is identical to the one in the key. If the signals match, the car will open and start. This is a great way to safeguard your car from theft.

Transponder keys are a popular addition to cars, but they're not as safe as traditional metal keys. The metal component of a traditional key can easily be cut and copied, however transponders have an electronic chip that protects it. The chip has a unique code that is inserted into a car's computers in 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 so if the key fob is equipped with a chip that is not modified that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match.

It's crucial to ensure that you have an extra key for your Saab. This is especially true if you live in a rural area where there are a lot of car burglars. The good part is that you can find a replacement key to your saab 93 key programming without having to go to an auto dealership and pay the high costs that they ask. In the majority of cases, you can have a brand new key made right on the spot for less than half the price of what you'd pay at the dealer.

Key for Wired

saab car key replacement cars typically come with two keys when they're new. If you only have one, you should get an extra key as soon as you can. This is because, if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There is no standard method to do this, but 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 to this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, you need to place a diode over each pin of the key switch and then solder it. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode allows current to flow in one direction, and it comes with a a black band visual indicator that indicates the direction current will flow.

Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY customers in some cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery in newer cars might not be the best option. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A surge in voltage when the battery is connected another battery could damage the components and render your vehicle unusable.

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

After the cables have been connected, start the car and let it run for approximately five minutes. Then, disconnect them in reverse. Be aware that the battery of your Saab 9-3 is charged during your drive, which means it could take a while for the battery to come down. It is a good idea to purchase a spare fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince it that your lost keys aren't trying to steal the car.

Replacement Case

Saab owners often only have one car key, and if it is lost, they will be charged. The reason is that it's costly to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in the event of theft or other disaster and the best option is to purchase an extra key as early as you can. Don't buy a secondhand key even it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail in the most critical moment.

The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the EEEPROM of your computer to make it ready to accept a replacement key without the need to replace the entire system. This can help you save a significant amount of money. It's cheaper to do this than wait until you lose your only key.
