15 Amazing Facts About Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 have an immobilizer feature that is based on codes for keys. The addition of a key requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The issue is that it can be very expensive. Always keep an extra set of keys on hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car then analyzes the signal to see whether it is identical to that of the key. If both signals match it will open itself and begin. This is a great method to prevent car theft and keep your car safe from thieves.
Transponder keys are an increasingly popular feature for cars, but they're not as secure as traditional keys made of metal. The metal component of a traditional key can be easily cut or copied, while transponders are protected by an electronic chip that protects it. The chip is equipped with an individual code that is embedded into the car's computer to identify it.
When a Saab key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if the fob has a non-modified chip that has been programmed to match it. Otherwise, the car would reject the key and refuse to start.
It is crucial to have an extra Saab key. This is especially important when you live in a rural area that is home to many car thieves. The good news is that it's possible to find a replacement key to your Saab without having to go to a dealer and pay the hefty prices that they demand. You can get the replacement key on the spot for less than half of what you would pay at a dealership.
Wired key
Saab cars typically come with two keys when new. If you only have one, it is best to acquire an additional key fob as quickly as you can as if you lose it, the car will require an entirely new CIM unit, and the locking cylinders will need to be replaced. This can be costly especially for used vehicles.
The Key Lab is connecting the wires for columns and row to your microcontroller. This is the most difficult component of the project and it will require lots of soldering. There is no standardized way to do this, but it's important to plan out the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.
Once the rows and columns are soldered, it's time to connect them to the key switches. To do this, put a diode across each key switch pin and then solder it. This will shield the pins that are used for key switches from current and also prevent them from being shorted. A diode only allows the flow of current to be in one direction, and it has an indicator in black that shows the direction in which current will flow.
Sanabria states that a number of the tools available in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer information. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.
Jump starting the battery
The majority of people have the set in their trunk to start a car in case of emergency, but this might not be the best idea for cars with more modern technology. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another can fry these components and leave your vehicle unable to drive.
Start the vehicle you are using and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled vehicle's hood. An engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which would ignite the gasoline inside the engine compartment.
Once the cables are connected, you can start the vehicle that is disabled and let it run for about five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It will take a while for it to fall back. You should invest in an additional key fob as soon as possible. The replacement of the one that works requires the installation and programming of a brand new computer chip.
Replacement case
Saab owners usually have only one car key, and if it is lost, they will be charged. The reason for this is that it's not cheap to add a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is best to have a backup key in the event of theft or other disaster and the best option is to purchase an additional key as quickly as you can. Even if the key is "new", it won't work.
The dealer will charge you the highest dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement key without the need to replace the entire system. This can save you a significant amount of money. It's also less expensive than waiting until you lose your only key.
