Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that relies on a set of keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that this can be quite costly. This is why you should always keep a spare key in your possession.

Transponder key

The transponder is a key equipped with an electronic chip. This chip sends out a signal when the key is put into the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and begin. This is a great way to stop car theft and keep your car secure from thieves.

Transponder keys can be a popular addition to automobiles, but they are not as secure as traditional metal keys. The metal component of the traditional key is easily copied and cut, but transponders have an electronic chip that guards it. The chip is a unique code which is programmed into the car's computer in order to identify it.

When a saab key fob (relevant web site) is used, the car recognizes it and allows it to turn on. However, it is only able to do this if your key fob has an unmodified chip that has been programmed to match. The car won't start in the event that the key has not been programmed to match.

It is crucial to have an extra Saab key. This is particularly important especially if you reside in a rural region where there are a lot of car burglars. You can obtain a replacement key for your saab 9-3 key fob replacement by going to the dealership, without having to pay their pricey cost. You can get a replacement key made on the spot for less than half of what you would pay at an auto dealer.

Key for Wired

Saab cars typically come with two keys when they are new. If you have only one, it is best to acquire an extra key fob as quickly as you can since if you lose it, the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be costly, especially if you are buying a used car.

The next step is connecting the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There's no standard way to go about it, but you should determine how to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has five rows and 17 columns.

After the rows and column are soldered together, it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins on the key switch from current and stop them from being shorted. A diode allows current to only flow in only one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.

Sanabria states that some of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO and IM508, Saab Key Fob can help customers shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunks for emergencies, but jumping a battery on modern vehicles may not be the best choice. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A surge of voltage when the battery is connected to another one could cause damage to the parts making your car inoperable.

Connect the cables to the vehicle operating. Allow it to 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 to a clean, unpainted metal surface beneath the hood of the affected vehicle. The engine block is an excellent choice. Don't connect the black cable to the negative terminal of the dead battery as this could trigger a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle and allow it to run for around five minutes. Then, disconnect them in reverse. Keep in mind that the battery on the Saab 9-3 will be charged while you drive, so it could take a while to get the battery back down again. You should invest in another key fob when you can. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Many Saab owners have only one key for their car and if they lose it, they'll be charged. The reason is that it's costly to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or any other catastrophe it is recommended to have a spare key. Even even if the key is "new", it won't work.

The dealer will charge the highest dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a new key without having to replace the entire system. This can save you a lot of money. It's less expensive rather than wait until you lose the sole key.
