15 Weird Hobbies That'll Make You Better At Saab Ignition Key Replacement
Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer feature based on coded keys. The addition of a key requires an entirely new transponder and programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
It can be costly. Always keep an extra set of keys available.
Transponder key
The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car will then check the signal to see if it matches the one on the key. If the signals are in sync the car will then open and start. This is a fantastic way to protect your car from theft.
Transponder keys are a favored feature in vehicles, but you should be aware that they aren't as secure as classic metal keys. The metal part of the traditional key is easily copied and cut, but a transponder has an electronic chip that safeguards it. The chip contains a unique code which is programmed into a car's computer in order to identify it.
When a Saab 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. Otherwise, the car will refuse to accept the key and will not start.
It's important to make sure that you have an extra key for your Saab. This is particularly important if you reside in a rural area with numerous car thieves. The good part is that you can find a replacement key to your Saab without having to go to a dealership and pay the hefty prices that they ask.

Saab cars are typically delivered with two keys. If saab key replacement have one, it's an ideal idea to purchase an additional key fob as quickly as you can since if you lose it, the car will require a new CIM unit and the locking cylinders need to be replaced. This can be expensive especially for cars that are used.
The next step is to connect the column and row wires to the microcontroller. This is the most laborious part of the project and it will require a lot of soldering. There is no standardized way to do this, but it is important to think about how you will route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.
After the rows and column are soldered together after which it is time to connect the key switches. To do this, put a diode over each pin of the key switch and then solder it. This will protect the pins on the key switch from current and also prevent them from being shorted. A diode lets current only flow in one direction. It features a visual indicator with a black band that shows the direction in which the current will flow.
Sanabria states that some of the tools offered in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer in the vehicle.
Jump starting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery for newer vehicles may not be the best idea. These vehicles are equipped with numerous computers and digital devices which communicate with each other. A voltage spike when batteries are connected to another battery could damage the components making your car unusable.
Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of the damaged car. The engine block is a great choice. Don't connect the black cable to the negative terminal on the dead battery because it could spark an ignition that ignites the gasoline in the engine bay.

Be aware that the battery in the Saab 9-3 will be charged during your drive, which means it can take a while to get the battery back to its original level. You should invest in another key fob when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement case
Saab owners often only have one car key, and if it is lost, they'll be charged. The reason is that it's not cheap to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in the event of theft or any other catastrophe and the most effective way is to buy an extra key as soon as you are able to. Don't buy a secondhand key, even when it's "new." Claimed-new keys purchased from third-party sellers won't work and are almost guaranteed to fail at the critical moment.
Most locksmiths aren't able to help if you have only one working key and the dealer will charge high fees to replace the computer in your vehicle to make a replacement. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without replacing the entire system. This can help you save money. It's also cheaper than waiting until you lose the only key.
