Saab Key Programming
Saab cars made since 1994 come with an immobilizer system built on coded keys. A new transponder is required for the inclusion of an additional key, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
The issue is that this could be quite costly. This is why you should always keep a spare key in your possession.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal to car when it is put into the ignition. The car then checks the signal to see whether it is the same as that of the key. If the signals are in sync the car will then unlock and begin. This is a great way to prevent car theft and keep your vehicle safe from thieves.
Transponder keys are a favored feature in automobiles, however you should be aware that they aren't as secure as classic keys made of metal. The metal component of the traditional keys can be easily cut or copied, while a transponder has an electronic chip that guards it. The chip is a unique code which 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 will only do this if the fob is unmodified and has a chip that has been programmed to match it. Otherwise, the car will reject the key and not start.
It's essential to ensure that you have an extra key for your Saab. This is especially important if you live in a rural location where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership, without having to pay their expensive costs. You can have the replacement key on the spot at a fraction of the price you'd pay at a dealership.
Wired key
Saab cars are usually supplied with two keys. If you own only one, you need to purchase an additional key as soon as you can. This is because if the key is lost the car will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially if you are buying a second-hand car.
The next step is to connect the wires for columns and rows to your microcontroller. This is the most tedious aspect of the project and it will require lots of soldering. There is no standard method to do this, but it is essential to determine the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered together It is now time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from being shorted. A diode lets current only flow in only one direction. It features a visual indicator of a black line that indicates the direction in which current will flow.
Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY users in some cases programme replacement keys and recover lost immobilizer data Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car's computer.
Jump-starting the battery
Most people keep a few sets of jumper cables in their trunks in case of emergency, but jumping a battery for newer cars might not be the best choice. They have numerous digital and computer systems that communicate with one another. A surge in voltage when batteries are connected to another can fry the components making your car inoperable.
Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the disabled vehicle. The engine block is an excellent 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 inside the engine compartment.
Once the cables are connected, start the vehicle that has been disabled and allow it to run for around five minutes before disconnecting them in reverse order. lost saab keys in your Saab 9-3 will recharge while you drive. It will take some time for it to drop back down. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and special programming to convince it that your lost keys aren't attempting to steal the car.
Replacement Case
Saab owners often only have one car key, and if it is lost, they'll 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, as well as programming. In the event of theft, or any other calamity, it is best to have an extra key. Even it's "new" it won't work.
Most locksmiths aren't able to help when you only have one working key, and the dealer will charge you top dollar to replace the computer in your vehicle for a replacement. We can reset and reprogram the EEEPROM of your computer for it to accept a new key without the need to replace the entire system. This could help you save a significant amount of money. It's much cheaper rather than wait until you lose the sole key.
