Ten Reasons To Hate People Who Can't Be Disproved 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 inclusion of an additional key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
It can be costly. Always keep an extra set of keys on hand.
Transponder key
The transponder key is a key with an electronic chip that transmits a signal to the car when it is put into the ignition. The car then analyzes the signal to see whether it is the same as that of the key. If the signals are identical, the car will unlock itself and begin. This is a great way to avoid car theft and keep your vehicle safe from thieves.
Transponder keys are a favored feature in automobiles, but it is important to know that they're not as secure as traditional metal keys. The metal component of a traditional key is easily cut and copied, however transponders have an electronic chip that guards it. The chip is equipped with a unique code that is programmed into the car's computer to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. However, it can only do this if your key fob has an unmodified chip that has been programmed to match it. Otherwise, the car would reject the key and won't start.
It's important to make sure that you have a spare key for your Saab. This is especially important when you live in a rural region where there are a lot of car thieves. You can obtain a replacement key for your Saab by going to the dealership, without having to pay their expensive costs. You can have a replacement key created on the spot for less than half of what you would spend at dealerships.
Key for Wired
Saab cars are usually delivered with two keys. If you only own one, you need to purchase 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 can be costly particularly for used cars.
The next step is to connect the row and column wires to the microcontroller. This is the most laborious part of the project and will require a lot of soldering. It's not a standard way to go about it, but you should plan how to route and solder each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
After saab key and column are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins of the key switch from current and also prevent them from being shorted. The diode allows current to only flow in only one direction. It is equipped with a visible indicator that is black, that shows which way current will flow.
Some of the tools offered 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 easier than replacing the vehicle's computer.
Jump-starting the battery
A lot of people keep a set of jumper cables in their trunk for emergencies however, jumping a battery on modern automobiles might not be the best choice. They have numerous computers and digital devices that communicate with each other. A voltage surge while the battery is connected to another battery could fry the components and render your car undriveable.
Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (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. Don't connect the black cable to the negative terminal of the dead battery, as it could ignite an ignition spark that ignites the gasoline in the engine bay.
After the cables have been connected, you can begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. The battery in the Saab 9-3 will charge while you drive. It will take a while for it to fall back. It's a good idea to purchase a spare fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and special programming to convince it that the lost keys are not trying to steal the car.
Replacement Case
Many Saab owners have only one key for their vehicle and if they lose that key, it will cost them. The reason is that it's expensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or other catastrophe, it is best to have a spare key. However, don't purchase a secondhand key even if it's "new." Keys that are claimed as new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the crucial moment.
Most locksmiths aren't able to help when you only have one working key and the dealer will charge for the cost of replacing the computer in your car for a replacement. However, we can reset and reprogram the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This can save you a significant amount of money. It's much cheaper instead of waiting until you lose the sole key.
