Saab Key Programming
Saab cars made from 1994 have an immobilizer system that is based on keys that are coded. To add an additional key, you need a new transponder, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
The issue is that it can be extremely expensive. It is always advisable to keep a spare set of keys on hand.
Transponder key
The transponder is a key with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car then checks the signal to see whether it is the same as the one that is in the key. If the signals are in sync then the car will be able to unlock and start. This is a great way to guard your car against theft.
Transponder keys are a favored feature in cars, but it is important to know that they aren't as secure as traditional keys made of metal. While the metal part of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. The chip is a unique code which is programmed into the car's computer in order to identify it.
The car will recognize the Saab keyfob and permit it to turn on. The car will only recognize the key fob if the device has a chip that is unmodified and programmed to match. In the absence of that, the car will reject the key and refuse to start.
It's important to make sure that you have an extra key for your saab key battery. This is particularly important if you live in a rural location where there are a lot of car burglars. The good part is that you can find a new key for your Saab without needing to visit an auto dealership and pay the expensive prices that they charge. You can have a replacement key made on the spot for less than half of what you would spend at a dealership.
Key for Wired
Saab cars usually come with two keys when they're new. If you have only one, you need to purchase an additional key as soon as you can. This is because if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.
The next step is to wire the wires of the column and row to the microcontroller. This is the most tedious aspect of the project and will require a lot of soldering. There is no standardized way to do this, but it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.
After the rows and column are joined then it's time to connect the key switches. To do this you must place an inverter over each pin of the key switch and then solder it. This will shield the pins on the key switch from current and keep them from being shorted. A diode permits current to only flow in only one direction. It has a visual indicator that is black, that shows which way current will flow.
Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY customers in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.
Jump starting the battery
A lot of people keep the set in their trunk to jump-start a car in case of emergency, but it may not be the best idea for vehicles that are newer. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A surge in voltage while the battery is connected to another could cause damage to these components, rendering your vehicle undriveable.
Start the vehicle that is working and let it run for about two minutes before you connect the cables to the disabled one. 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 of the black cable to an unpainted, clean metal surface beneath the damaged car's hood--the engine block is a good option. Don't connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition source that ignites 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 your saab replacement key programming 9-3 will recharge as you drive. It will take some time for it to return to its original state. It is a good idea to invest in a spare key fob as soon as you can, because replacing the one that works 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 key, it will cost them. The reason is that it's expensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft or other catastrophe, it is best to have a spare key. Don't purchase a used key even when it's "new." Claimed-new keys from sellers selling aftermarket keys won't perform and are almost certain to fail at the critical moment.
The dealer will charge you the most expensive dollar if you have only one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept a new key without replacing the whole system. This can help you save money. It's much cheaper than waiting until you lose your only key.
