What Will Saab Ignition Key Replacement Be Like In 100 Years?
Saab Key Programming
Saab cars built since 1994 use an immobilizer system that is based on keys that are coded. To add an additional key, you need a new transponder and special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The problem is that this can be very expensive. Always keep a spare set of keys in your possession.
Transponder key
The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are in sync then the car will be able to unlock and begin. This is a great way to protect your car from theft.
Transponder keys are a popular addition to cars, but they are not as safe as traditional keys made of metal. The metal component of a traditional keys can be easily copied and cut, but transponders are protected by an electronic chip which protects it. The chip contains a unique code that 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. However, it is only able to do so if the key fob is equipped with a chip that is not modified that has been programmed to match the original. The car will not start in the event that the key is not programmed to match.
It's important to make sure that you have a spare key for your Saab. This is especially important for those who live in a rural area where there are many car thieves. You can get a new key for your Saab by going to the dealership without paying expensive costs. In most instances, you can get a brand new key made right on the spot for less than half the cost of what you'd pay at a dealer.
Wired key
Saab cars usually come with two keys when they're new. If you only have one, you should get an additional key as soon as you can. This is because if the key is lost and the car needs a new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.
The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and will require a lot of soldering. There's no standard way to accomplish this, but it is important to think about the route you'll take and solder the rows and columns. There are 22 microcontroller pins and wires to connect to this keyboard. It includes 5 rows and 17 columns.
After the rows and column are soldered together then it's time to connect the key switches. To do this, you need to place a diode on each pin on the key switch and solder it. This will shield the pins on the key switch from current and stop them from being shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator, a black band, that indicates which direction current will flow.
Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump starting the battery
A lot of people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery for newer vehicles might not be the most efficient option. These vehicles have many electronic devices and computers that communicate with one another. A surge in voltage while a battery is hooked up to another battery could fry these components and leave your car undriveable.
Start the vehicle that is working and allow it to run for approximately two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood--the engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery because it could spark a spark that ignites the gasoline in the engine bay.
After the cables have been connected, you need to begin the car and allow it to run for around five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to recharge again. It is recommended to purchase an additional key fob as soon as you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Many Saab owners have only one key for their car and if they lose that the cost will be. The reason for this is that it's not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other disaster it is recommended to have a spare key. But don't buy a used key, even if it's "new." Keys that are claimed as new from a second-hand store will not work and are almost guaranteed to fail at the crucial moment.
Most locksmiths cannot help you if you have only one working key and the dealer will charge you high fees to replace the computer in your vehicle to make a replacement. saab key can, however, reset and reprogram the computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This could save you a significant amount of money. It's much cheaper rather than wait until you lose the only key.
