Saab Key Programming

saab key programmer cars manufactured since 1994 use an immobilizer that relies on a set of keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. It is recommended to always have an extra set of keys available.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is inserted into ignition. The car then analyzes the signal to see whether it is the same as the one in the key. If both signals match it will open itself and start. This is a great way to avoid auto theft and keep your vehicle safe from thieves.

Transponder keys may be an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. The metal component of the traditional keys can be easily cut or copied, while a transponder has an electronic chip which protects it. The chip has a unique code programmed into the car's computer to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if it is equipped with a chip that is unmodified and programmed to match. The car will not start when the key isn't programmed to match.

It's essential to ensure that you have a spare key for your saab replacement key programming. This is especially important especially if you live in a rural area that is home to many car thieves. The good part is that you can find a new key for your Saab without having to go to a dealer and pay the high prices they ask. You can get a replacement key created on the spot for less than half of what you would pay at dealerships.

Key for Wired

Saab ignition key cars typically come with two keys upon purchase. If you only have one, it is recommended to purchase an additional key fob as soon as possible since if you lose it the car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This could be expensive, especially if you are purchasing a used vehicle.

The next step is to wire the wires for the column and row to the microcontroller. This is the most laborious part of the project, and will require lots of soldering. It's not a common way to go about it, but you should determine how to route and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It includes 5 rows and 17 column.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the key switch pins from current and keep them from being shorted. The diode will only allow current to flow in one direction, and it has an indicator in black that indicates 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 help customers in the shop, or even DIY customers in certain cases create replacement keys and restore lost immobilizer information, Sanabria says. The tools plug into OBD ports and guide the user through each step and make the process more straightforward than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a set in their trunks to jump-start a car in an emergency, but it might not be a good idea for vehicles that are newer. These vehicles have many electronic devices and computers that communicate with one another. A voltage spike when a battery is hooked up to another could cause damage to the components and render your car unable to drive.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of your disabled car. The engine block is a great choice. Don't connect the black cable to the negative terminal on the dead battery, since this could cause a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should begin the car and let it run about five minutes. Then, disconnect the cables in reverse. Remember that the battery on your Saab 9-3 is recharged when you drive, so it could take a while to get the battery down. It's a good idea to purchase 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 your missing keys aren't in the process of trying to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, the cost will be. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. In the event of theft or any other catastrophe it is best to have an extra key. However, don't purchase a secondhand key, even if it's "new." Claimed-new keys from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the most critical moment.

The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This can save you a lot of money. It's much cheaper than wait until you loose the only key.
