This Is The Ultimate Guide To Saab Ignition Key Replacement
Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer system that relies on a set of keys. A new transponder is required for addition of an extra key, and special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that this could be extremely expensive. You should always keep an extra set of keys on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to the car when it is inserted into the ignition. The car will then check the signal to determine whether it is identical to the one on the key. If the signals match, the car will open and start. This is a great way to guard your car against theft.

Transponder keys can be an extremely popular accessory for cars, but they are not as safe as traditional metal keys. The metal component of the traditional key can easily be cut or copied, while the transponder is protected by an electronic chip that safeguards it. The chip is a unique code that is inserted into a car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key is not programmed to match.

It's crucial to ensure that you have a spare key for your Saab. This is especially important if you reside in a rural area with many car thieves. You can get a brand new key for your Saab by going to the dealership, without having to pay their pricey prices. You can have an original key made on the spot for less than half of what you would spend at dealerships.

Wired key

Saab cars are usually provided with two keys. If you only have one, you should purchase an additional key as soon as you can. This is because, if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This could be expensive, especially if you are buying a second-hand car.

The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and will require a good amount of soldering. It's not a standard way to go about it, but you must consider how you will route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the key switch pins from current and also prevent them from being shorted. The diode will only allow current to flow in one direction, and has a a black band visual indicator that indicates the direction current will flow.

Sanabria says that some of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 will assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step, making the process easier 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, but jumping a battery for newer vehicles might not be the best idea. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A voltage surge when the battery is connected to another can fry the components making your car inoperable.


Connect the cables to the vehicle working. 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 a clean, unpainted metal surface underneath the car's hood. The engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery, since this could cause 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 for approximately five minutes. Then, disconnect them in reverse. Be aware that the battery in the Saab 9-3 will be charged during your drive, which means it may take some time to get the battery back to normal. saab fob key replacement TheKeyLab is recommended to purchase a second key fob, as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their car and if they lose that they'll be charged. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft, or any other catastrophe it is advisable to have a spare key. Even when the key is "new" it won't work.

The dealer will charge the highest dollar for only one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept the new key, without replacing the whole system. That can help you save money. It's also a lot cheaper than waiting until you lose your one key.
