Saab Key Programming

Saab cars built since 1994 utilize an immobilizer system that relies on coded keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

It can be costly. This is the reason why you should always have a spare key on hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to the car when it is inserted into ignition. The car then examines the signal to see whether it is the same as the one on the key. If the signals are identical it will open itself and begin. This is an excellent way to protect your car from theft.

Transponder keys can be an extremely popular accessory for cars, but they’re not as secure as traditional keys made of metal. While the metal parts of a traditional key may be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code embedded into the car’s computer to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. But, it’s only able to do this if the key fob has an unmodified chip that has been programmed to match the original. In the absence of that, the car will reject the key and won’t start.

It’s important to make sure that you have a spare key for your saab key replacement. This is especially true if you reside in a rural area with numerous car thieves. The good news is that it’s possible to find a replacement key to your saab Ignition key replacement without having to go to a dealership and pay the hefty prices that they ask. You can have a replacement key created on the spot at a fraction of what you would pay at the dealership.

Wired key

Saab cars are usually provided with two keys. If you have only one, it’s best to acquire an additional key fob as quickly as you can, because if you lose it, your car will require an entirely new CIM unit, and the locking cylinders will have to be replaced. This can be costly, especially for used cars.

The next step is to wire 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. There isn’t a standard method to go about it, but you need to determine how to route and connect each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has five rows and 17 columns.

After the columns and rows are soldered, it’s the time to connect them to the key switches. To do this, place a diode across each key switch pin and solder it. This will shield the pins from current and prevent them from getting shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator that is black, that shows which way current will flow.

Sanabria states that some of the tools available in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 can assist customers shopping or DIY users to program replacement keys and restore the immobilizer’s data. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the car’s computer.

Jump starting the battery

A majority of people keep the set in their trunks to start a car in case of emergency, but this might not be a good option for vehicles with newer technology. These vehicles are equipped with many electronic devices and computers that communicate with one another. A surge in voltage when the battery is connected to another battery could damage the components, rendering your car undriveable.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will read “POS” or “+”.) Attach the other end to a clean unpainted metal surface underneath the hood of the damaged car. The engine block is a great option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline in the engine compartment.

Once the cables are connected, start the vehicle and let it run about five minutes. Then disconnect them in reverse. The battery in your saab replacement keys 9-3 will be recharged while you drive. It takes a while for it to recharge again. You should invest in 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

saab 9-3 replacement key owners usually only have one car key, and if that is lost, they will be charged. The reason for this is that it’s not inexpensive to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a spare key in case of theft or any other catastrophe and the best option is to buy an extra key as soon as you can. Don’t buy a secondhand key even the case that it’s “new.” Keys that are claimed to be new from a second-hand store will not work and are almost guaranteed to fail at the crucial moment.

The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the computer’s EEEPROM for it to accept a replacement key without having to replace the entire system. This could save you a significant amount of money. It’s more affordable than wait until you lose the only key.
