20 Tools That Will Make You More Effective At Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since about 1994 have an immobilizer system built on coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer using the Tech2 diagnostic tool.
It can be costly. This is why you should always keep a spare key in your possession.
Transponder key
The transponder is a key that is equipped with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are identical, the car will unlock itself and begin. This is a fantastic way to protect your car from theft.
Transponder keys are an extremely popular accessory for cars, but they are not as safe as traditional metal keys. While the metal parts of a conventional key can be cut and copied, a transponder is protected by an electronic chip. The chip is equipped with a unique code programmed into the car's computer to identify it.
The car will recognize the Saab keyfob, and allow it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and programmed to match. The car will not start in the event that the key has not been programmed to match.
It is vital to have an extra Saab key. This is especially important for those who live in a rural location that has many car thieves. You can get a brand new key for your Saab by visiting the dealership without paying expensive prices. In the majority of instances, you can get a new key created on-the-spot at a fraction of the cost you'd pay at an auto dealer.
Wired key
Saab cars usually come with two keys when they are new. If saab key programmer have one, it's recommended to purchase an extra key fob as soon as you can in case you lose it, your car will require an entirely new CIM unit and the locking cylinders have to be replaced. This could be expensive particularly if you are purchasing a used car.
The next step is to wire the column and row wires to the microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There's no standard way to do it, but you should think about how to route and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It includes 5 rows and 17 column.
After the rows and column are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current and prevent them from being shortened. A diode permits current to only flow in one direction. It features a visual indicator with a black band that indicates which direction current will flow.
Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could aid shop customers or DIY customers in certain instances replace keys in the program and restore lost immobilizer data Sanabria says. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.
Jumpstarting the battery
The majority of people have an item in their trunk to start a vehicle in the event of an emergency, but it might not be a good option for vehicles with newer technology. These vehicles are equipped with many electronic devices and computers that communicate with each other. A voltage spike when a battery is hooked up to another battery could fry the components and render your vehicle undriveable.
Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the affected car. The engine block is a good alternative. Do not connect the black cable to the negative terminal of the dead battery, as it could spark a spark that ignites the gasoline in the engine bay.
Once the cables are connected, start the disabled vehicle and let it run for about five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to drop back down. It's a good idea to invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your missing keys are not trying to steal the car.
Replacement case
Many Saab owners have only one key for their vehicle and if they lose it, the cost will be. The reason is that it's expensive to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a spare key in the event of theft or other disaster the best solution is to purchase an additional key as early as you can. Even even if the key is "new" it will not function.
The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement 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 loose the only key.
