How To Save Money On Saab Ignition Key Replacement
Saab Key Programming
Saab cars manufactured since 1994 have an immobilizer feature that is based on codes for keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
This can be expensive. This is the reason why you should always have a spare key on hand.
Transponder key
The transponder key is a key equipped with an electronic chip. It sends a signal to the car when it is placed in the ignition. The car then examines the signal to see whether it is the same as the one that is in the key. If the signals are identical the car will be able to unlock itself and begin. This is a fantastic way to protect your car from theft.
Transponder keys are an increasingly popular feature in automobiles, but you must be aware that they aren't as secure as traditional metal keys. The metal component of a traditional key is easily cut and copied, however transponders have an electronic chip that safeguards it. This chip contains an unique code that is programmed into a car's computer 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 if it has a chip that is unmodified and has been programmed to match. Otherwise, the car would reject the key and refuse to start.
It is crucial to have a spare Saab key. This is particularly important especially if you live in a rural area with many car thieves. The good news is that you can get a replacement key for your Saab without having to go to a dealership and pay the expensive prices that they charge. In the majority of instances, you can get a new key created on-the-spot for less than half the cost of what you would pay at dealerships.
Wired key
Saab cars are usually provided with two keys. If you have only one, it is a good idea to get an extra key fob as soon as you can, because if you lose it the car will require the replacement of a CIM unit and the locking cylinders will need to be replaced. This could be expensive particularly if you are buying a second-hand car.
The next step is connecting the wires of columns and row to your microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. There's no standard way to go about it, but you must plan how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.
Once the rows and columns are soldered, it's time to connect them to key switches. To do this, you need to place a diode on each pin of the key switch and then solder it. This will shield the pins from current, thus preventing them from being cut off. A diode only allows the current to flow in a single direction, and it has the black band as a visual indicator that indicates the direction current will flow.
Sanabria says that a few of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 can assist customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's data. 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 the set in their trunks to jump-start a vehicle in the event of an emergency, but it might not be the best option for vehicles with newer technology. These cars are equipped with a variety of computers and digital devices which communicate with one another. A voltage spike when the battery is connected to another can fry these components, rendering your vehicle unable to drive.
Connect the cables to the vehicle that is operating. Allow it to run for two minutes. 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, unpainted metal surface beneath the hood of the affected car. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks, which would ignite the gasoline that is in the engine compartment.
Once the cables are connected, you should start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will recharge as you drive. It takes a while for it to recharge again. It is recommended to purchase an additional key fob when you can. Replacing the one that works requires the installation and programming of a new computer chip.
saab key replacement have one car key, and if it is lost, they will be charged. It's expensive to purchase the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other catastrophe it is advisable to have a spare key. Even it's "new", it won't work.
The dealer will charge you the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This can help you save money. It's also much less expensive than waiting until you lose your sole key.
