Are You Getting The Most Value From Your Saab Ignition Key Replacement?
Saab Key Programming
Saab cars that were built prior to 1994 come with an immobilizer system that is based on codes for keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.
This can be expensive. It is always advisable to keep an extra set of keys in your possession.
Transponder key
The transponder is a key that is equipped with an electronic chip. The chip sends a signal when the key is placed in the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals match, the car will unlock itself and begin. This is an excellent way to protect your car from theft.
Transponder keys are a popular feature in vehicles, but you should be aware that they aren't as secure as traditional metal keys. The metal part of the traditional key is easily cut and copied, whereas a transponder has an electronic chip that guards it. This chip contains an individual code that is programmed into the car's computers to identify it.
The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key is not programmed to match.
It is crucial to have an extra Saab key. This is particularly important if you live in a rural location where there are numerous car thieves. The good news is that it's possible to find a new key for your Saab without needing to visit an auto dealership and pay the high prices that they demand. You can have a replacement key made on the spot for less than half the price you'd pay at an auto dealer.
Wired key
Saab cars are usually delivered with two keys. If you only own one, you should purchase an extra key as soon as you can. This is because, if it's lost the car will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if buying a used car.
The next step is connecting the wires of columns and row to your microcontroller. This is the most laborious part of the project, and it will require a lot of soldering. There isn't a standard method to go about it, but you must think about how to route and connect each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's time to connect them to key switches. To do this, place an inverter over each pin on the key switch and then solder it. This will shield the pins on the key switch from current and prevent them from being shorted. A diode allows current to only flow in one direction. It features a visual indicator that is black, that indicates the direction in which current will flow.
Sanabria states that some of the tools sold in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508, can help customers who are shopping or DIY users to program replacement keys and restore immobilizer information. The tools plug into OBD ports and help the customer through each step and make the process more straightforward than replacing the car's computer.
Jumpstarting saab replacement keys of people have an item in their trunk to jump-start their car in an emergency, but it may not be the best option for vehicles with newer technology. These vehicles are equipped with a number of computers and digital devices that communicate with one another. A surge of voltage when the battery is connected to another one could cause damage to the parts making your car unusable.
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's good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery, as this could cause an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, start the car and let it run about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It may take a while it to fall back. You should consider purchasing an additional key fob as soon as you can. The replacement of the one that works requires the installation and programming of a new computer chip.
Replacement case
Saab owners often only have one car key, and if that is lost, they'll be charged. The reason for this is that it's expensive to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other catastrophe, it is best to have an extra key. Don't buy a secondhand key even if it's "new." Keys that are claimed-new from a second-hand store will not perform and are almost certain to fail at the crucial moment.
Most locksmiths aren't able to help if you have only one working key, and the dealer will charge you high fees to replace the computer in your car to make a new replacement. We can reset and reprogram the EEEPROM of your computer for it to accept a replacement key without the need to replace the entire system. This could save you a lot of money. It's cheaper to do this than wait until you lose the sole key.
