Are You Getting The Most Of Your Saab Ignition Key Replacement?
Saab Key Programming
Saab cars built since about 1994 feature an immobilizer mechanism built on coded keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
saab 93 replacement key is that this can be very 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. The chip transmits a signal when the key is inserted 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 the car will then unlock and start. This is a great way to guard your car against theft.
Transponder keys are a popular addition to cars, but they are not as secure as traditional metal keys. While the metal portion of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip is equipped with an unique code that is encoded into the car's system to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. However, it is only able to do this if the key fob is unmodified and has a chip that has been programmed to match it. The car won't start in the event that the key has not been programmed to match.
It's important to make sure that you have an extra key for your Saab. This is particularly important if you live in a rural area, where there are a lot of car burglars. The good thing is that you can find a new key for your Saab without needing to visit an auto dealership and pay the expensive prices that they charge. In the majority of cases, you can have an original key made on the spot at a fraction of the cost you'd pay at dealerships.
Key for Wired
Saab cars usually come with two keys upon purchase. If you only own one, you need to purchase an additional key as soon as you can. This is because, if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly especially if buying a second-hand car.
The next step is to connect the column and row wires to the microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There's no standard way to do this, but it is essential to determine the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.
Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the key switch pins from current and keep them from being shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator that is black, that shows the direction in which the current will flow.
A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- may assist customers at the shop or DIY users in some cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer in the vehicle.
Jumpstarting the battery
The majority of people have a set in their trunk to start a car in case of emergency, however it might not be a good idea for newer cars. They have numerous electronic devices and computers that communicate with each other. A surge in voltage while a battery is hooked up to another battery could fry these components, rendering your vehicle undriveable.
Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood--the engine block is an excellent choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks, which could ignite the gasoline that is in the engine compartment.
Once the cables are connected, you should start the vehicle and let it run for approximately five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge while you drive. It may take a while it to recharge again. It is a good idea to purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and a special program to convince it that the lost keys aren't attempting to steal the car.
Replacement Case
Many Saab owners only have one key for their car and if they lose it, the cost will be. The reason for this is that it's expensive to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other disaster it is best to have a spare key. Don't buy a secondhand key, even it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't perform and are almost certain to fail in the most critical moment.
Most locksmiths cannot help you in the event that you only have one working key, and the dealer will charge high fees to replace the computer in your car for a replacement. However, we can reset and reprogram the computer's EEPROM to accept the new key without having to replace the entire system. This could save you a significant amount of money. It's also cheaper than waiting until you lose your sole key.
