14 Misconceptions Common To Saab Ignition Key Replacement
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 in order to enable the addition of an extra key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The issue is that this could be very costly. This is why you should always have a spare key at hand.
Transponder key
The transponder keys are keys equipped with an electronic chip. saab replacement keys sends a signal to the car when it is inserted into the ignition. The car then checks the signal to determine whether it is identical to the one in the key. If the signals are the same the car will be able to unlock itself and begin. This is a great method to safeguard your car from theft.
Transponder keys are an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. The metal component of the traditional key is easily cut and copied, whereas the transponder is protected by an electronic chip that guards it. The chip has a unique code that is inserted into a car's computers in order to identify it.
The car will recognize the Saab keyfob and permit it to be turned on. The car will only recognize the key fob when it has an unmodified chip and has been programmed to match. If not, the car will reject the key and won't start.
It is essential to ensure that you have an extra key for your Saab. This is especially important if you live in a rural area where there are a lot of car thieves. The good thing is that you can find a replacement key to your Saab without having to go to an auto dealership and pay the hefty prices they ask. In most instances, you can get a new key created on-the-spot for less than half the price of what you would pay at a dealer.
Wired key
Saab cars are usually delivered with two keys. If you own only one, you should purchase an extra key as soon as you can. This is because if the key is lost the car will require a new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.
The next step is to wire the column and row wires to the microcontroller. This is the most tedious aspect of the project and will require a lot of soldering. It's not a standard way to do it, but you need to plan how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.
After the columns and rows are joined It is now time to connect the key switches. To do this, place a diode on each pin on the key switch and then solder it. This will protect the pins of the key switch from current and keep them from being shorted. The diode allows current to only flow in only one direction. It has a visual indicator that is black, that shows which way current will flow.
Sanabria says that a few of the tools sold in auto parts stores, such as the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to 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
Most people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery for newer vehicles may not be the best choice. These cars are equipped with a variety of digital and computers that communicate with each other. A surge of voltage when the battery is connected to another one could cause damage to the parts making your car inoperable.
Connect the cables to the vehicle that is working. Let it 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 of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be an ideal choice. Don't connect the black cable to the negative terminal on the dead battery, since it could spark an ignition that ignites the gasoline in the engine bay.
Once the cables are connected, begin the car and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to return to its original state. You should purchase another key fob as soon as possible. Replacing the one that works requires the installation and programming of a new computer chip.
Replacement case
Many Saab owners have only one key for their car and if they lose that it's going to cost them. It's expensive to buy keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft or other catastrophe it is advisable to have a spare key. Don't purchase a used key even it's "new." Keys that are claimed-new from aftermarket sellers will not be effective and are almost guaranteed to fail at the critical moment.
Most locksmiths can't help you with a single working key and the dealer will charge you high prices to replace the computer in your vehicle for a replacement. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without replacing the entire system. That can save you a significant amount of money. It's cheaper to do this instead of waiting until you lose the only key.
