Saab Key Programming
Saab cars manufactured since 1994 come with an immobilizer system built on coded keys. A new transponder is required for the addition of an extra key, and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
It can be costly. This is why it is important to always keep a spare key in your possession.
Transponder key
The transponder is a key equipped with an electronic chip. The chip transmits a signal when the key is placed into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are in sync the car will then open and start. This is a great way to avoid car theft and keep your vehicle secure from thieves.
Transponder keys are a favored feature in automobiles, however you should be aware that they are not as secure as classic metal keys. The metal part of the traditional key can be easily copied and cut, but a transponder has an electronic chip that safeguards it. The chip has a unique code that is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob, and allow it to turn on. However, it will only do this if the fob is equipped with a chip that is not modified that has been programmed to match the original. Otherwise, the car will refuse to accept the key and will not start.
It's essential to ensure that you have a spare key for your Saab. This is particularly true when you live in a rural location that has many car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying their expensive prices. In the majority of cases, you can have a brand new key made right on the spot for less than half the cost you would pay at dealerships.
Key for Wired
Saab cars are usually delivered with two keys. If you only have one, it's recommended to purchase an additional key fob as quickly as you can, because if you lose it, the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be costly particularly for used cars.
The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard way to accomplish this, however it is important to think about the way you'll route and solder the columns and rows. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 columns.
After the rows and column are soldered together, it is time to connect the key switches. To do this, put a diode across each pin of the key switch and solder it. This will protect the pins from current and prevent them from being shortened. A diode only allows the flow of current to be in one direction, and it comes with a the black band as a visual indicator that indicates which way the current will flow.
Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can assist customers at the shop or DIY customers in certain instances program replacement keys and restore the lost immobilizer's data, Sanabria says. 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.
Jump-starting the battery
The majority of people have an item in their trunks to start a vehicle in an emergency, but it might not be the best idea for cars with more modern technology. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A surge in voltage while a battery is hooked up to another could cause damage to the components and render your car unable to drive.
Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the battery that is not working. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach saab key programming near me of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block would be a good choice. Don't connect the black cable to the negative terminal of the dead battery as this could cause a spark that ignites the gasoline in the engine bay.
After the cables have been connected, begin the car and let it run for approximately five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to drop back down. It is a good idea to invest in a spare key fob as soon as you can, because replacing the only working one requires the installation of a brand new computer module and special programming to convince it that your lost keys are not trying to steal the car.
Replacement Case
Many Saab owners only have one key for their vehicle and if they lose it, the cost will be. It's expensive to purchase an additional key and it requires replacing the CIM or TWICE in the case of older models. It is recommended to have a second key in case of theft or other disaster the best solution is to buy an extra key as soon as you can. Don't purchase a used key even when it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't perform and are almost certain to fail at the crucial moment.
The dealer will charge you the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM to make it ready to accept a new key without replacing the entire system. This could save you a great deal of money. It's more affordable than wait until you loose the only key.
