10 Things Everybody Hates About Saab Ignition Key Replacement
Saab Key Programming
Saab cars produced from 1994 have an immobilizer system that is based on keys that are coded. A new transponder is required for the inclusion of an additional key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
The problem is that this could be extremely expensive. You should always keep an extra set of keys at hand.
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 will then check the signal to determine whether it matches the one on the key. If the signals match the car will then open and start. This is a fantastic way to protect your vehicle from theft.
Transponder keys are a common feature in automobiles, however you should be aware that they're not as secure as traditional metal keys. The metal portion of a traditional keys can be easily copied and cut, but a transponder has an electronic chip that guards it. The chip is equipped with an unique code that is embedded into the car's computer to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car will only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and not start.
It is important to have a spare Saab key. This is especially true if you reside in a rural region that has numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership and not paying their pricey costs. In most cases, you can have a new key created on-the-spot at a fraction of the cost you would pay at a dealer.
Wired key
Saab cars usually come with two keys upon purchase. If you only have one, you should get an additional key as quickly as you can. This is because if you lose it the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used car.
The next step is to connect the row and column wires to the microcontroller. This is the most tedious part of the project, and it will require lots of soldering. There isn't a standard way to do this, but it is important to think about the way you'll route and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has five rows and 17 column.
After the rows and column are joined It is now time to connect the key switches. To do this, place an inverter over each key switch pin and then solder it. This will shield the pins that are used for key switches from current and keep them from being shorted. saab replacement key allows current to only flow in one direction. It has a visual indicator, a black band, that indicates which direction current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may help customers in the shop, or even DIY customers in some cases create replacement keys and restore lost immobilizer data Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.
Jump-starting the battery
Most people keep a set of jumper cables in their trunks to use in an emergency however, jumping a battery on modern cars might not be the best choice. They have numerous digital and electronic devices that communicate with each other. A surge in voltage when the battery is connected another could cause damage to the components and render your vehicle unusable.
Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of your disabled vehicle. The engine block is a great option. Don't connect the black cable to the negative terminal on the dead battery as it could ignite an ignition that ignites the gasoline in the engine bay.
Once the cables are connected, you can start the vehicle that has been disabled and allow it to run for around five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 will recharge while you drive. It may take a while it to drop back down. It's a good idea purchase a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.
Replacement Case
Saab owners usually have only one car key, and if that is lost, they will be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. It's recommended to have a second key in the event of theft or other disaster and the most effective way is to buy an extra key as soon as you can. Even even if the key is "new", it will not work.
The dealer will charge you the most expensive dollar for only one working key. However, we can reset and re-program the computer's EEPROM in order to prepare it to accept the new key, without replacing the entire system. This could save you a great deal of money. It's cheaper to do this rather than wait until you lose your only key.
