Saab Key Programming
Saab cars manufactured from 1994 have an immobilizer system that is based on coded keys. A new transponder is required for addition of a second key, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.
The problem is that it can be very expensive. This is the reason why you should always keep a spare key in your possession.
Transponder key
The transponder is a key that has an electronic chip. This chip sends out a signal when the key is inserted into the ignition. The car will then check the signal to see whether it is the same as 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 way to avoid car theft and keep your vehicle safe from thieves.
Transponder keys are a favored feature in vehicles, but it is important to know that they are not as secure as traditional metal keys. While the metal part of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. The chip contains a unique code which is programmed into the car's computer in order to identify it.
When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it will only do this if the key fob has an unmodified chip that has been programmed to match it. The car will not start when the key isn't programmed to match.
It is essential to ensure that you have a spare key for your Saab. This is especially important for those who live in a rural location where there are many car thieves. You can purchase a new key for your Saab by visiting the dealership, without having to pay their high cost. You can have a replacement key created on the spot for less than half of the cost you would spend at an auto dealer.
Key for Wired
Saab cars are usually delivered with two keys. If you only have one, you need to purchase an additional key as quickly as you can. This is because if you lose it, the car will need an entirely new CIM and the locking cylinders replaced. This could be expensive particularly if you are purchasing a used car.
The next step is to connect the wires for columns and row to your microcontroller. This is the most laborious part of the project and will require lots of soldering. There is no standard method to accomplish this, but it is essential to determine the route you'll take and solder the columns and rows. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
After the columns and rows are joined It is now time to connect the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will protect the key switch pins from current and also prevent them from being shorted. A diode lets current only flow in one direction. It comes with a visual indicator with a black band that indicates which direction current will flow.
Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the customer through the procedure, making it much easier than replacing the computer in the vehicle.
Jumpstarting the battery
Most people keep a few sets of jumper cables in their trunk for emergency situations, but jumping a battery for newer automobiles might not be the best idea. These vehicles are equipped with many electronic devices and computers that communicate with one another. A voltage spike when a battery is hooked up to another battery could fry these components and leave your vehicle unable to drive.
Start the vehicle that is working and let it run for about two minutes before connecting the cables to the one that is disabled. Attach saab 93 replacement key The Key Lab 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 disabled car's hood. The engine block would be a good choice. Do not connect the black cable to the negative terminal of the dead battery as it could ignite an ignition that ignites the gasoline in the engine bay.
Once the cables are connected the disabled vehicle and allow it to run for around five minutes before disconnecting them in reverse order. Be aware that the battery in the Saab 9-3 will be charged when you drive, so it could take a while to get the battery back to its original level. You should consider purchasing another key fob as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.
Replacement case
Saab owners usually have only one car key, and if that is lost, they'll be charged. The reason for this is that it's not cheap to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or any other calamity, it is best to have an extra key. Even when the key is "new", it will not work.
The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without replacing the entire system. This could save you lots of money. It's more affordable than waiting until you lose the sole key.
