Saab Key Programming

Saab cars built since 1994 utilize an immobilizer system that relies on key codes. In order to add a second key, it requires a new transponder and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that this can be very costly. This is why it is important to always have a spare key on hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car then checks the signal to determine whether it is identical to the one in the key. If both signals match the car will be able to unlock itself and start. This is a great method to stop auto theft and keep your car safe from thieves.

Transponder keys could be an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal component of a traditional key can be easily copied and cut, but a transponder has an electronic chip which protects it. The chip has a unique code that is programmed into the car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. However, it is only able to do this if your key fob is unmodified and has a chip that has been programmed to match the original. Otherwise, the car would refuse to accept the key and will not start.

It's crucial to ensure that you have a spare key for your Saab. This is particularly true especially if you live in a rural location that has numerous car thieves. You can get a brand new key for your saab 93 key by going to the dealership without paying pricey prices. In the majority of cases, you can have a new key made on-the-spot for less than half the price of what you would pay at the dealer.

Wired key

saab 93 key fob cars are typically delivered with two keys. If you have only one, it is recommended to purchase an additional key fob as quickly as you can, because if you lose it, your car will require a new CIM unit and the locking cylinders have to be replaced. This could be expensive particularly if you are buying a used car.

The next step is to connect the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a good amount of soldering. It's not a standard way to go about it, but you should consider how to Open a saab replacement key programming 93 without a key (Tst.ezmir.co.kr) you will route and connect each column and row. 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 soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins from current, preventing them from being shorted. A diode only allows current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.

Sanabria says that a few of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 can assist customers shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jump starting the battery

Most people keep a set of jumper cables in their trunk for emergency situations, but jumping a battery for newer vehicles may not be the best choice. These cars have a variety of digital and computer systems that communicate with one another. A voltage surge when batteries are connected to another battery could damage the components, rendering your car undriveable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block is a good choice. Do not connect the black cable to the negative terminal of the dead battery, as this could trigger a spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle you are not using and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge while you drive. It will take a while for it to return to its original state. You should consider purchasing another key fob as soon as possible. Replacing the original 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 it is lost saab key, they will be charged. It's expensive to buy the key and also requires replacing the CIM or TWICE for older models. In the event of theft or other catastrophe, it is best to have an extra key. Even it's "new" it will not work.

The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to accept the new key, without replacing the entire system. This could save you lots of money. It's cheaper to do this than wait until you loose the only key.
