Saab Key Programming

saab 9-3 replacement key cars manufactured since 1994 have an immobilizer system based on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder can be described as a key that has an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then analyzes the signal to see whether it is the same as the one in the key. If the signals match the car will then open and start. This is a great method to stop car theft and keep your car secure from thieves.

Transponder keys are an increasingly popular feature in vehicles, but you should be aware they aren't as secure as traditional metal keys. The metal portion of a traditional key can be easily cut and copied, whereas the transponder is protected by an electronic chip that protects it. The chip is equipped with an individual code that is 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. The car can only recognize the key fob if it has an unmodified chip and has been programmed to match. If not, the car will refuse to accept the key and will not start.

The next step is to wire the column and row wires to the microcontroller. This is the most laborious component of the project and will require lots of soldering. There's no standard way to do this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this you must place a diode on each key switch pin and solder it. This will shield the pins from current, thus preventing them from getting shorted. A diode allows current to flow in one direction, and it also has a a black band visual indicator that indicates the direction in which current will flow.

Sanabria says that some of the tools that are sold in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on modern vehicles may not be the most efficient option. These cars are equipped with a variety of digital and computers that communicate with each other. A surge in voltage when the battery is connected another could cause damage to the components 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 good battery (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. Do not connect the black cable to the negative terminal on the dead battery, since this could cause an ignition source that ignites gasoline in the engine bay.

After the cables have been connected, begin the car and let it run for about five minutes. Then, disconnect the cables in reverse. Remember that the battery on the Saab 9-3 gets recharged when you drive, so it can take a while for the battery to come back to normal. It's a good idea buy a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and a special program to convince the system that your lost keys aren't trying to steal the car.

Replacement case

Saab owners usually only have one car key, and if it is lost, they will be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. It is recommended to have a second key in the event of theft or other disaster and the most effective way is how to program saab 9-3 key fob purchase an additional key as quickly as you can. But don't buy a used key even when it's "new." Claimed-new keys from a second-hand store will not be effective and are almost guaranteed to fail in the crucial moment.

The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without the need to replace the entire system. This could help you save a significant amount of money. It's also much less expensive than waiting until you lose the only key.
