Saab cars produced since 1994 feature an immobilizer system that relies on keys that are coded. To add an additional key, you need the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this could be extremely expensive. Always keep an extra set of keys available.

Transponder key

The transponder key comes with an electronic chip that sends a signal to the car when it is inserted into the ignition. The car then checks the signal to see whether it is the same as the one in the key. If the signals are in sync the car will then unlock and begin. This is a great way to safeguard your car from theft.

Transponder keys are a common feature in automobiles, however it is important to know that they're not as secure as traditional metal keys. While the metal parts of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip has a unique code that's programmed into a car's computer order to identify it.

When a saab keys key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match it. The car won't start in the event that the key is not programmed to match.

It is essential to have a spare Saab key. This is particularly important for those who live in a rural area with numerous car thieves. You can obtain a replacement key for your saab 93 key programming by going to the dealership without paying their expensive costs. You can have an original key made on the spot for less than half the price you'd spend at the dealership.

Key for Wired

saab key fob replacement cars typically come with two keys upon purchase. If you own only one, you should get an additional key as quickly as you can. This is because if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is to connect the column and row wires to the microcontroller. This is the most tedious part of the project, and it will require a lot of soldering. It's not a standard way to do it, but you must determine how to connect and solder each column and row. 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 together, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from being cut off. A diode only allows the flow of current to be in one direction, and it comes with a the black band as a visual indicator that indicates the direction in which current will flow.

Sanabria states that some of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 are able to assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jumpstarting the battery

A lot of people keep the set in their trunks to jump-start a vehicle in an emergency, but this might not be the best option for vehicles with newer technology. These vehicles have many digital and electronic devices that communicate with one another. A surge in voltage when a battery is hooked up to another one could damage these components, rendering your car unable to drive.

Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip on 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 underneath the car's hood. The engine block is a good option. Do not connect the black cable to the negative terminal of the dead battery, since this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you need to start the car and let it run about five minutes. Then disconnect them in reverse. The battery in the Saab 9-3 will charge as you drive. It will take a while for it to fall back. You should invest in 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

saab spare key owners typically only have one car key, and if it is lost, they'll be charged. The reason is that it's not cheap to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It is best to have a second key in case of theft or any other catastrophe and the best option is to purchase a second key as early as you can. Even it's "new" it will not function.

The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without the need to replace the entire system. This can save you a lot of money. It's also much less expensive than waiting until you lose the only key.
