Saab Key Programming

Saab cars made since 1994 have an immobilizer feature made up of coded keys. A new transponder is required for the inclusion of an additional key, and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

This can be expensive. It is always advisable to keep an extra set of keys on hand.

Transponder key

The transponder is a piece of key with an electronic chip. This chip sends out a signal when the key is placed in the ignition. The car then examines the signal to determine if it matches the one in the key. If the signals match the car will then open and start. This is a great method to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in automobiles, but it is important to know that they are not as secure as classic keys made of metal. While the metal portion of a traditional key could be cut and copied, a transponder is protected by an electronic chip. The chip is equipped with a unique code programmed into the car's computers to identify it.

When a saab 9 3 key replacement key fob is used the car recognizes it and allows it to turn on. However, it is only able to do this if the fob has an unmodified chip that has been programmed to match. The car won't start if the key is not programmed to match.

Key for Wired

Saab cars are typically delivered with two keys. If you own only one, you need to purchase an extra key as soon as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly especially if you're buying a second-hand car.

The next step is to connect the column and row wires to the microcontroller. This is the toughest aspect of the project and will require lots of soldering. There's no standard way to do this, but it is essential to determine the way you'll route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined, it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins from current, thus preventing them from getting shorted. The diode will only allow the flow of current to be in one direction, and has a a black band visual indicator that indicates the direction current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could assist customers at the shop or DIY users in some cases create replacement saab car keys keys and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.

Jumpstarting the battery

A majority of people keep a set in their trunk to jump-start a vehicle in the event of an emergency, but it may not be the best idea for newer cars. These vehicles are equipped with many electronic devices and computers that communicate with each other. A surge of voltage when batteries are connected to another can fry the components and render your vehicle unusable.

Start the working vehicle and let it run for about 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 read "POS" or "+".) Attach the other end to a clear, unpainted metal surface beneath the hood of the damaged car. The engine block is an excellent alternative. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline in the engine compartment.

Once the cables are connected, you should begin the car and let it run for about five minutes. Then, disconnect the cables in reverse. Remember that the battery on the Saab 9-3 will be charged during your drive, which means it can take a while for the battery to come back down again. It is a good idea to invest in a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and a special program to convince it that the lost keys aren't in the process of trying to steal the car.

Replacement Case

Many saab replacement keys owners only have one key for their vehicle and if they lose it, key, it will cost them. It's costly to add the key and also requires replacing the CIM or TWICE in the case of older models.

The dealer will charge the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without the need to replace the entire system. This could save you a lot of money. It's much cheaper than waiting until you lose the sole key.
