saab 9-3 key programming Key Programming

Saab cars built since 1994 utilize an immobilizer system based on a set of keys. A new transponder is required for the addition of a second key, and special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. It is always advisable to keep a spare set of keys available.

Transponder key

The transponder is a key that is 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 see whether it is the same as the one on the key. If the signals match the car will then unlock and start. This is a great method to deter car theft and keep your vehicle secure from thieves.

Transponder keys could be an extremely popular accessory for cars, but they are not as safe as traditional metal keys. The metal component of the traditional key can easily be copied and cut, but transponders have an electronic chip which protects it. This chip contains an unique code that is programmed into a car's computer order to identify it.

The car will recognize the saab Ignition key, montgomery-jamison-2.technetbloggers.de, keyfob, and allow it to turn on. However, it will only do this if the fob is unmodified and has a chip that has been programmed to match. The car won't start when the key isn't programmed to match.

Key for Wired

Saab cars are usually provided with two keys. If you have only one, it's a good idea to get an additional key fob as quickly as you can as if you lose it, your car will require a new CIM unit, and the locking cylinders need to be replaced. This can be expensive, especially for used cars.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. There isn't a 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 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 soldered, it's time to connect them to the key switches. To do this you must place a diode on each key switch pin and then solder it. This will shield the pins from current, and prevent them from being cut off. A diode allows the flow of current to be in one direction, and it has an indicator of black color that indicates the direction current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- may help shop customers or even DIY customers in certain cases program replacement keys and restore lost saab keys immobilizer information, Sanabria says.

Jump starting the battery

Most people keep an item in their trunk to start a car in an emergency, but this might not be the best idea for newer cars. These vehicles are equipped with computers and digital devices which communicate with each other. A surge in voltage when batteries are connected to another battery could damage the components making your car inoperable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip to the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the disabled car's hood--the engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery, as it could spark a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should start the vehicle and let it run for approximately five minutes. Then disconnect the cables in reverse. Keep in mind 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 go back down again. It's 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 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 vehicle and if they lose it, key, it will cost them. The reason is that it's not inexpensive to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other disaster, it is best to have a spare key. Even it's "new", it won't work.

Most locksmiths can't help you in the event that you only have one working key, and the dealer will charge you top dollar to replace the computer in your vehicle for a replacement saab car keys. We can, however, reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the entire system. This could save you a lot of money. It's less expensive than waiting until you loose the only key.
