Saab Key Programming

saab ignition key cars manufactured since 1994 have an immobilizer system made up of coded keys. A new transponder is required for addition of an additional key, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The problem is that this can be very costly. This is why you should always have a spare key on hand.

Transponder key

The transponder is a key that is equipped with an electronic chip. This chip sends out a signal when the key is inserted in the ignition. The car then analyzes the signal to see whether it is identical to the one on the key. If the signals are in sync the car will then open and start. This is an excellent way to safeguard your car from theft.

Transponder keys can be an extremely popular accessory for cars, but they're not as safe as traditional metal keys. The metal portion of a traditional key can be easily cut or copied, while a transponder has an electronic chip which protects it. This chip contains an individual code that is programmed into the car's computers to identify it.

When a saab key fob replacement 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 has been programmed to match. The car will not start when the key isn't programmed to match.

It is essential to have an extra Saab key. This is particularly important when you live in a rural area that is home to many car thieves. You can purchase a new key for your Saab by visiting the dealership without paying their expensive prices. You can get a replacement key made on the spot at a fraction of what you would spend at a dealership.

Key for Wired

Saab cars are usually supplied with two keys. If you have only one, it's an ideal idea to purchase an additional key fob as soon as is possible, because if you lose it, your car will require the replacement of a CIM unit, and the locking cylinders have to be replaced. This can be costly especially for used vehicles.

The next step is to connect the wires for columns and rows to your microcontroller. This is the toughest part of the project, and will require lots of soldering. There is no standard method to accomplish this, however it's important to plan out how you will route and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It includes 5 rows and 17 column.

After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins on the key switch from current and also prevent them from being shorted. A diode only allows the current to flow in a single direction, and it also has a a black band visual indicator that indicates which way the current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jump starting the battery

A lot of people keep the set in their trunks to start a vehicle in the event of an emergency, but it may not be the best option for vehicles with newer technology. These vehicles are equipped with a number of electronic devices and computers that communicate with one another.

Don't connect the black cable to the negative terminal of the dead battery as this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, [Redirect Only] you need to begin the car and let it run about five minutes. Then, disconnect them in reverse. Remember that the battery on your saab 9-3 replacement key 9-3 is charged when you drive, so it may take some time to get the battery back down again. You should consider purchasing a second key fob, when you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement Case

Many Saab owners have only one key for their car and if they lose that they'll be charged. The reason is that it's expensive to replace a key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's recommended to have a second key in case of theft or any other catastrophe the best solution is to purchase an additional key as quickly as you can. But don't buy a used key even it's "new." Keys that are claimed-new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.

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