5 Things That Everyone Is Misinformed About Concerning Saab Ignition Key Replacement
Saab Key Programming

Saab cars built from 1994 have an immobilizer system based on key codes. A new transponder is required for the addition of a second key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

It can be costly. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder is a type of key with an electronic chip. This chip sends a signal when the key is put into the ignition. The car checks to see whether the signal matches the one on the key. If the signals match it will unlock and start. This is a great way to prevent car theft and keep your vehicle safe from thieves.

Transponder keys are a common feature in vehicles, but you should be aware that they're not as secure as traditional metal keys. saab 9-3 replacement key of a traditional keys can be easily cut and copied, whereas a transponder has an electronic chip that protects it. The chip has an unique code that is programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and allow it to be turned on. The car can only recognize the key fob if the device has an unmodified chip and has been programmed to match. Otherwise, the car would reject the key and won't start.

It's crucial to ensure that you have an extra key for your Saab. This is particularly important especially if you reside in a rural area where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership without paying high prices. In most cases, you can have an original key made on the spot for less than half the price of what you'd pay at the dealer.

Key for Wired

Saab cars are usually provided with two keys. If you only own one, you need to purchase an extra 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 can be expensive, especially for used cars.

The next step is connecting the wires of columns and row to your microcontroller. This is the most tedious aspect of the project and will require lots of soldering. There's no standard way to go about it, however, you should determine how to route and connect each column and row. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 column.

After the columns and rows are joined, it is time to connect the key switches. To do this, place a diode on each pin of the key switch and solder it. This will protect the key switch pins from current and stop them from being shorted. A diode lets current only flow in only one direction. It has a visual indicator, a black band, that shows the direction in which the current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in some cases program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.


Jump-starting the battery

A majority of people keep an assortment of tools in their trunks to start a car in an emergency, but it might not be a good idea for cars with more modern technology. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A surge in voltage when batteries are connected to another one could cause damage to the parts, rendering your car undriveable.

Start the working vehicle and let it run for about two minutes before connecting the cables to the one that is disabled. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of the disabled vehicle. The engine block is a great choice. Do not connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you can start the disabled vehicle and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to drop back down. It is a good idea to purchase a spare fob as soon as you can, since replacing the only working one requires the installation of a new computer module and a special program to convince it that your missing keys are not trying to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose that the cost will be. The reason is that it's expensive to replace a key, and that involves 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 it's "new" it won't work.

The dealer will charge the highest dollar for only one working key. However, we can reset and re-program the computer's EEPROM to accept the new key without having to replace the entire system. This could save you a great deal of money. It's also much less expensive than waiting until you lose your only key.
