saab Ignition key (https://Glamorouslengths.com/author/congapencil57/) Key Programming
saab 9 3 key replacement cars built since about 1994 come with an immobilizer system based on coded keys. Adding an extra key requires a new transponder and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
This can be expensive. It is always advisable to keep a spare set of keys on hand.
Transponder key
The transponder key is a key with an electronic chip that transmits a signal to the car when it is inserted into the ignition. The car will then check the signal to determine whether it matches that of the key. If the signals are in sync then the car will be able to unlock and begin. This is a great method to avoid auto theft and keep your car safe from thieves.
Transponder keys are an increasingly popular feature for cars, but they are not as secure as traditional metal keys. While the metal parts of a conventional key can be cut and copied, a transponder is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computers 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 it is equipped with an unmodified chip and has been programmed to match. The car will not start in the event that the key is not programmed to match.
It is important to have a spare Saab key. This is especially true for those who live in a rural area with many car thieves. The good part is that you can obtain a replacement key for your saab replacement key without having to go to a dealer and pay the high costs that they ask. You can have an original key made on the spot at a fraction of what you would spend at a dealership.
Key for Wired
Saab cars typically come with two keys when they are new. If you own only one, you should purchase an additional key as soon as you can. This is because, if it's lost the car will require a new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used vehicle.
The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. It's not a standard way to do it, but you need to plan how to route and connect each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has five rows and 17 column.
After the columns and rows are soldered together It is now time to connect the key switches. To do this, you need to place an inverter over each pin on the key switch and then solder it. This will protect the pins from current, thus preventing them from being shorted. A diode can only allow the flow of current to be in one direction, and has a a black band visual indicator that shows the direction in which current will flow.
Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY customers in certain instances program replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.
Jump-starting the battery
Most people keep the set in their trunk to jump-start a car in an emergency, however it might not be the best idea for cars with more modern technology. These vehicles have many electronic devices and computers that communicate with one another. A surge in voltage while the battery is connected to another could cause damage to these components, rendering your vehicle undriveable.
Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clean unpainted metal surface under the hood of the damaged car. The engine block is a good alternative. Do not connect the black cable to the negative terminal of the dead battery, since it could spark an ignition source that ignites gasoline in the engine bay.
Once the cables are connected the vehicle that is disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery in the Saab 9-3 gets recharged when you drive, so it will take a while for the battery to go back down again. You should purchase a second key fob, when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Many saab 93 replacement key owners have only one key for their car and if they lose that the cost will be. The reason for this is that it's not cheap to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other calamity it is advisable to have a spare key. Even it's "new" it won't work.
The dealer will charge you the highest dollar for only one working key. We can, however, reset and re-program your computer's EEPROM to accept an alternative key without replacing the whole system. That can save you a lot of money. It's more affordable than wait until you lose the only key.
