Saab Key Programming

saab Key fob programming cars that were built prior to 1994 have an immobilizer system based on coded keys. Adding an extra key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. It is always advisable to keep an extra set of keys available.

Transponder key

The transponder key comes with an electronic chip that transmits a signal to the car when it is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If the signals are the same, the car will unlock itself and start. This is a great method to deter auto theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in automobiles, but you should be aware they aren't as secure as traditional keys made of metal. While the metal portion of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code that is programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. However, it can only do this if your key fob has an unmodified chip that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match.

If you only have one, it is an ideal idea to purchase an extra key fob as soon as is possible in case you lose it the car will require the replacement of a CIM unit and the locking cylinders have to be replaced. This can be expensive especially for used vehicles.

The next step is to connect the wires for the column and row to the microcontroller. This is the most difficult part of the project and it will require lots of soldering. There's no standard way to do this, but it is important to think about the routes you'll use to solder the columns and rows. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together after which it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the pins on the key switch from current and stop them from being shorted. A diode allows current to only flow in one direction. It has a visual indicator with a black band that shows which way current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can assist customers at the shop or DIY users in some cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks in case of emergency, but jumping a battery for newer cars might not be the best choice. These cars have a variety of digital and computer systems that communicate with each other. A voltage spike when the battery is connected to another one could damage these components and leave your car undriveable.

Start the vehicle that is working 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 have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of the damaged car. The engine block is a great alternative. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, you need to start the vehicle and allow it to run for around five minutes. Then, disconnect them in reverse. Remember that the battery on the saab 900 Key 9-3 will be charged when you drive, so it will take a while for the battery to come back to normal. You should invest in a second key fob, as soon as possible. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement Case

Many Saab owners have only one key for their car and if they lose that it's going to cost them. The reason is that it's not cheap to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or any other catastrophe it is advisable to have a spare key. Even even if the key is "new" it will not work.

The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and re-program the computer's EEPROM how to open a saab 93 without a key accept the new key without having to replace the whole system. This could save you a lot of money.
