Saab Key Programming
Saab cars built since about 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required for addition of a second key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
It can be costly. This is why you should always keep a spare key in your possession.
Transponder key
The transponder key comes with an electronic chip that sends a signal back to the car when it is put into the ignition. The car then checks to see whether the signal matches with the one on the key. If the signals are in sync the car will then unlock and begin. This is a great method to prevent car theft and keep your vehicle safe from thieves.
Transponder keys are a common feature in cars, but you must be aware that they are not as secure as classic keys made of metal. The metal portion of a traditional key can be easily cut and copied, whereas a transponder has an electronic chip which protects it. This chip contains an unique code that is inserted into the 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 can only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and won't start.
It is crucial to have an extra Saab key. This is particularly important for those who live in a rural area, where there are numerous car thieves. You can get a brand new key for your Saab by visiting the dealership without paying expensive costs. You can have the replacement key on the spot at a fraction of the price you'd pay at an auto dealer.
Wired key
Saab cars are usually provided with two keys. If you own only one, you need to purchase an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.
The next step is connecting the wires for columns and rows to your microcontroller. This is the most tedious part of the project and it will require a lot of soldering. There is no standardized way to accomplish this, however it is essential to determine the routes you'll use to solder the rows and columns. There are 22 microcontroller wires and pins to connect for this keyboard. It has 5 rows and 17 column.
After the columns and rows are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins of the key switch from current and prevent them from being shorted. saab replacement keys uk G28CarKeys will only allow the current to flow in a single direction, and it has the black band as a visual indicator 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 and IM508 can assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.
Jumpstarting the battery
The majority of people have a set of jumper cables in their trunks for emergency situations however, jumping a battery for newer automobiles might not be the best idea. They have numerous digital and electronic devices that communicate with one another. A surge in voltage when a battery is hooked up to another one could damage these components, rendering your vehicle unable to drive.
Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood--the engine block is an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline that is in the engine compartment.
After the cables have been connected, start the car and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will recharge while you drive. It will take some time for it to fall back. It is recommended to purchase a second key fob, as soon as possible. Replacing the 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 it, the cost will be. The reason is that it's costly to buy a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other disaster, it is best to have a spare key. Even if the key is "new" it will not function.
The dealer will charge you the highest dollars if you only have one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a replacement key without the need to replace the entire system. This can save you a lot of money. It's also a lot cheaper than waiting until you lose your one key.
