10 Best Mobile Apps For Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since 1994 utilize an immobilizer system that relies on keys that are coded. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The issue is that this can be extremely expensive. You should always keep an extra set of keys available.
Transponder key
The transponder is a piece of key with an electronic chip. The chip transmits a signal when the key is inserted in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals match the car will then unlock and start. This is a great method to safeguard your car from theft.
Transponder keys are a popular addition to automobiles, but they are not as secure as traditional metal keys. While the metal parts of a traditional key could be cut and copied, a transponder is protected by an electronic chip. The chip contains a unique code which is programmed into a car's computers in order 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 your key fob is equipped with a chip that is not modified that has been programmed to match. The car won't start in the event that the key has not been programmed to match.
It's important to make sure that you have a spare key for your Saab. This is particularly important for those who live in a rural location where there are 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 dealership and pay the expensive prices that they demand. You can get a replacement key created on the spot for less than half what you would pay at dealerships.
Wired key
Saab cars are usually delivered with two keys. If you only have 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 if you are buying a used car.
The next step is connecting the wires for columns and row to your microcontroller. This is the most laborious component of the project and it will require a lot of soldering. There isn't a standard method to do it, but you should determine how to route and connect each column and row. For saab replacement keys , there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this you must place a diode on each pin of the key switch and then solder it. This will protect the pins from current and prevent them from getting shorted. The diode allows current to only flow in only one direction. It comes with a visual indicator of a black line that indicates the direction in which current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY users in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the user through each step which makes the process much easier than replacing the car's computer.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunks for emergency situations however, jumping a battery on modern vehicles may not be the best option. These vehicles are equipped with many computers and digital devices which communicate with one another. A voltage spike when the battery is connected to another could cause damage to the components and render your vehicle unable to drive.
Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface under the hood of your disabled vehicle. The engine block is a good alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite the gasoline that is in the engine compartment.
After the cables have been connected, you should begin the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. Be aware that the battery of the Saab 9-3 will be charged while you drive, so it can take a while for the battery to go back down again. It is a good idea to buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince the system that your lost keys are not trying to steal the car.
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 costly to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a spare key in case of theft or other disaster and the best option is to purchase an extra key as early as you can. But don't buy a used key, even it's "new." Claimed-new keys purchased from third-party sellers won't work and are likely to fail in the crucial moment.
Most locksmiths cannot help you in the event that you only have one working key and the dealer will charge high prices to replace the computer in your vehicle to make a new replacement. However, we can reset and re-program your computer's EEPROM to accept the new key without having to replace the entire system. This can help you save a significant amount of money. It's also cheaper than waiting until you lose your one key.
