20 Things You Need To Be Educated About Saab Ignition Key Replacement Saab Key Programming

Saab cars made since 1994 feature an immobilizer mechanism that is based on codes for keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The problem is that this could be very expensive. It is always advisable to keep an extra set of keys available.

Transponder key

The transponder is a key equipped with an electronic chip. This chip sends a signal when the key is put into the ignition. The car then checks the signal to determine whether it is identical to the one on the key. If the signals match the car will then unlock itself and begin. This is a great way to deter auto theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in vehicles, but you must be aware that they're not as secure as classic metal keys. The metal portion of a traditional key is easily cut or copied, while a transponder has an electronic chip that protects it. The chip contains a unique code that's programmed 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. The car will only recognize the key fob if it is equipped with an unmodified chip and programmed to match. The car won't start in the event that the key is not programmed to match.

It's essential to ensure that you have a spare key for your Saab. This is especially true when you live in a rural location where there are many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying their pricey prices. In most instances, you can get a brand new key made right on the spot at a fraction of the price of what you would pay at an auto dealer.

Wired key

Saab cars are usually delivered with two keys. If you only have one, it's a good idea to get an additional key fob as soon as is possible as if you lose it the car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This could be expensive, especially if you are buying a used car.

The next step is to connect the wires of columns and row to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to do it, however, you should plan how to route and solder each column and row. 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 to each key switch pin. This will shield the pins that are used for key switches from current and stop them from being shorted. The diode allows current to only flow in one direction. It comes with a visual indicator of a black line that shows the direction in which the current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep the set in their trunks to start a vehicle in an emergency, but it might not be the best idea for vehicles that are newer. These vehicles are equipped with a number of computers and digital devices that communicate with each other. A surge of voltage when a battery is connected to another can fry the components making your car unusable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of the damaged car. saab key replacement is a good choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite gasoline in the engine compartment.


After the cables have been connected, begin the car and allow it to run for around five minutes. Then, disconnect them in reverse. Remember that the battery on your Saab 9-3 is recharged during your drive, which means it can take a while for the battery to come back to normal. You should invest in another key fob as soon as possible. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Many Saab owners only have one key for their car and if they lose that it's going to cost them. The reason is that it's expensive to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or other catastrophe, it is best to have an extra key. Even even if the key is "new" it won't work.

The dealer will charge you top dollar 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 replacing the entire system. That can save you a lot of money. It's less expensive instead of waiting until you lose your only key.
