This Is The Ultimate Guide To Saab Ignition Key Replacement
Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer system built on coded keys. A new transponder is required for the addition of an additional key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The problem is that this could be very costly. This is the reason why you should always have a spare key available.
Transponder key
The transponder key comes with an electronic chip that sends a signal to car when it is put into the ignition. The car will then check the signal to determine whether it is the same as the one in the key. If the signals are in sync the car will then unlock and begin. This is a great way to avoid car theft and keep your car safe from thieves.
Transponder keys are a popular addition to cars, but they're not as safe as traditional metal keys. The metal component of the traditional key can easily be copied and cut, but transponders are protected by an electronic chip that guards it. The chip has a unique code that is inserted into a car's computer in order to identify it.
The car will recognize the saab key code keyfob and permit it to be turned on. The car will only recognize the key fob when it has an unmodified chip and has been programmed to match. If not, the car will reject the key and refuse to start.
It is essential to have a spare saab spare key key. This is especially true when you live in a rural region that has numerous car thieves. You can obtain a replacement key for your saab 9-3 key programming by visiting the dealership without paying pricey prices. You can have a replacement key created on the spot for less than half the price you'd spend at a dealership.
Wired key
saab key code cars usually come with two keys when new. If you only own one, you should get an additional key as quickly as you can. This is because, if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used car.
The next step is to connect the column and row wires to the microcontroller. This is the most tedious part of the project, and will require lots of soldering. It's not a standard way to do it, however, you should think about how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and prevent them from being shorted. A diode allows current to flow in one direction, and it has an indicator of black color that indicates the direction in which current will flow.
Sanabria says that a few of the tools available in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and help the customer through each step and make the process more straightforward than replacing the car's computer.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks in case of emergency however, jumping a battery in newer cars might not be the most efficient option. These vehicles are equipped with a number of electronic devices and computers that communicate with each other. A surge in voltage when a battery is connected to another can fry the components making your car unusable.
Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.
Once the cables are connected, start the vehicle that is disabled and let it run for approximately five minutes before disconnecting them in reverse order. Be aware that the battery in the saab keys 9-3 gets recharged when you drive, so it may take some time to get the battery down. It's a good idea to purchase a spare fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and special programming to convince it that your missing keys aren't attempting to steal the car.
Replacement case
Many Saab owners only have one key for their car and if they lose that the cost will be. The reason is that it's not inexpensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or other catastrophe, it is best to have a spare key. Even when the key is "new" it won't work.
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 for it to accept a replacement key without having to replace the entire system. This could save you a lot of money. It's much cheaper rather than wait until you lose the only key.
