Three Reasons Why You're Saab Ignition Key Replacement Is Broken (And How To Fix It)
Saab Key Programming
Saab cars made since 1994 feature an immobilizer mechanism based on coded keys. A new transponder is required for addition of a second key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
This can be expensive. You should always keep a spare set of keys on hand.
Transponder key
The transponder is a type of key with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then analyzes the signal to determine whether it is the same as the one that is in the key. If the signals match, the car will unlock and start. This is a great way to deter auto theft and keep your vehicle safe from thieves.
Transponder keys are a favored feature in automobiles, however it is important to know that they are not as secure as traditional keys made of metal. The metal part of the traditional key is easily copied and cut, but the transponder is protected by an electronic chip which protects it. The chip has a unique code that's programmed into a car's computer in order to identify it.
The car will recognize the Saab keyfob and allow it to be turned 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 original. In the absence of that, the car will reject the key and not start.
It's crucial to ensure that you have a spare key for your Saab. This is especially true especially if you reside in a rural area, where there are a lot of car burglars. You can purchase a new key for your Saab by visiting the dealership and not paying their pricey cost. You can get an original key made on the spot for less than half the cost you would spend at an auto dealer.
Wired key
Saab cars are usually provided with two keys. If saab key programmer have one, it is recommended to purchase an additional key fob as soon as you can in case you lose it the car will require the replacement of a CIM unit, and the locking cylinders need to be replaced. This can be costly especially if purchasing a used vehicle.
The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There isn't a standard way to accomplish this, however it is important to think about the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect to this keyboard. It includes 5 rows and 17 column.
After the columns and rows are soldered together then it's time to connect the key switches. To do this, place an inverter over each pin of the key switch and solder it. This will protect the pins from current, preventing them from being cut off. A diode can only allow the flow of current to be in one direction, and it also has a a black band visual indicator that indicates the direction current will flow.
A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY users in some cases program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the customer through each step, making the process easier than replacing the vehicle's computer.
Jump starting the battery
The majority of people have a set in their trunks to jump-start a car in an emergency, however it might not be a good option for vehicles with newer technology. These vehicles are equipped with a number of electronic devices and computers that communicate with each other. A surge in voltage when the battery is connected to another can fry these components and leave your vehicle undriveable.
Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the disabled one. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood--the engine block is an ideal choice. Do not connect the black cable to the negative terminal of the dead battery, as it could spark an ignition source that ignites gasoline in the engine bay.
After the cables have been connected, you can start the vehicle and allow it to run for around five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 is recharged while you drive. It will take a while for it to return to its original state. It's a good idea purchase a spare fob as soon as you can, because replacing the only working one requires the installation of a new computer module and special programming to convince it that the lost keys are not trying to steal the car.
Replacement Case
Many Saab owners have only one key for their vehicle and if they lose that the cost will be. The reason is that it's expensive to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in case of theft or any other catastrophe and the best option is to purchase an additional key as soon as you are able to. Even even if the key is "new", it won't work.
Most locksmiths aren't able to help with a single working key and the dealer will charge for the cost of replacing the computer in your car for a replacement. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without replacing the entire system. This can save you a significant amount of money. It's also less expensive than waiting until you lose your sole key.
