Saab Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that is based on key codes. A new transponder is required in order to enable the inclusion of an additional key, and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that this could be quite costly. This is why it is important to always have a spare key at hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. The chip sends a signal when the key is placed into the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are in sync it will unlock and start. This is a great method to avoid auto theft and keep your vehicle secure from thieves.

Transponder keys may be a popular addition to automobiles, but they are not as safe as traditional metal keys. The metal component of a traditional key is easily copied and cut, but transponders have an electronic chip that safeguards it. The chip is equipped with an unique code that is embedded 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 when it has a chip that is unmodified and programmed to match. Otherwise, the car will reject the key and refuse to start.

It is vital to have a spare Saab key. This is particularly important for those who live in a rural region where there are many car thieves. The good news is that it's possible to find a new key for your Saab without having to go to an auto dealer and pay the high costs that they charge. You can get an original key made on the spot at a fraction of what you would pay at dealerships.

Wired key

Saab cars typically come with two keys upon purchase. If you only have one, it is recommended to get an additional key as quickly as you can. This is because if you lose it and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

The next step is to connect the wires for columns and row to your microcontroller. This is the toughest part of the project and will require lots of soldering. It's not a standard way to do it, but you should plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, [empty] it's the time to connect them to key switches. To do this, place an inverter over each pin of the key switch and then solder it. This will shield the pins of the key switch from current and keep them from being shorted. A diode only allows the flow of current to be in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY customers in some cases program replacement keys and restore lost saab keys immobilizer data, Sanabria says. The tools connect to OBD ports and guide the user through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks for emergency situations, but jumping a battery on modern automobiles might not be the best choice. These vehicles are equipped with many digital and computers that communicate with each other. A surge in voltage while a battery is hooked up to another could cause damage to these components and leave your vehicle undriveable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the vehicle's hood. An engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery because it could spark an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run for about five minutes. Then, disconnect them in reverse. The battery in the Saab Replacement Key Programming 9-3 will charge as you drive. It takes a while for it to fall back. It is a good idea to buy a spare key fob as soon as you can, since replacing the only working one requires the installation of a new computer module and special programming to convince it that the lost keys are not trying to steal the car.

Replacement Case

Many saab 93 key fob owners only have one key for their car and if they lose it, [empty] the cost will be. It's expensive to add the key and also requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster, and the best way is to purchase an additional key as early as you can. Don't purchase a used key even if it's "new." Keys that are claimed as new from a second-hand store will not perform and are almost certain to fail at the crucial moment.

Most locksmiths cannot help you in the event that you only have one working key, and the dealer will charge high fees to replace the computer in your car to make a new replacement. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept a new key without replacing the entire system. This could help you save a significant amount of money. It's also a lot cheaper than waiting until you lose your only key.
