Saab Key Programming

Saab cars built since 1994 utilize an immobilizer system that relies on key codes. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

This can be expensive. This is why it is important to always have a spare key on hand.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car then checks the signal to determine whether it is identical to the one on the key. If the signals are identical the car will be able to unlock itself and begin. This is a great method to avoid car theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in vehicles, but you should be aware they aren't as secure as traditional keys made of metal. The metal component of the traditional key can easily be copied and cut, but transponders are protected by an electronic chip that guards it. The chip has a unique code which is programmed into a car's computer in order to identify it.

When a saab 9 3 key replacement - full report - key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if the fob has a non-modified chip that has been programmed to match it. Otherwise, the car will reject the key and not start.

It is crucial to have a spare Saab key. This is particularly true if you reside in a rural area with many car thieves. The good news is that it's possible to find a replacement key to your saab 93 key replacement without having to go to a dealer and pay the high costs they ask.

This is because if you lose it and the car needs a new CIM and the locking cylinders replaced. This can be costly particularly if you are purchasing a used car.

The next step is connecting the wires of columns and row to your microcontroller. This is the most difficult aspect of the project and it will require a lot of soldering. There is no standardized way to accomplish this, however it is important to think about the way you'll route and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this you must place a diode on each pin on the key switch and solder it. This will protect the pins from current, thus preventing them from being shorted. The diode will only allow the current to flow in a single direction, and it has the black band as a visual indicator that shows 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 aid shop customers or DIY customers in certain cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the user through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have the set in their trunks 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 computers and digital devices which communicate with one another. A voltage spike when the battery is connected to another one could cause damage to the parts, rendering your car undriveable.

Connect the cables to the vehicle that is working. Let it run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface beneath the damaged car's hood. The engine block is an ideal choice. Don't 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 need to start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. Remember that the battery on your saab 93 key 9-3 is recharged while you drive, so it will take a while to get the battery back to its original level. You should purchase an additional key fob as soon as you can. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose it, it's going to cost them. The reason for this is that it's not cheap to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other disaster it is advisable to have a spare key. Don't buy a secondhand key, even it's "new." Claimed-new keys purchased from third-party sellers won't perform and are almost certain to fail in the crucial moment.

Most locksmiths aren't able to help in the event that you only have one working key, and the dealer will charge you for the cost of replacing the computer in your vehicle to create a replacement. We can reset and reprogram the computer's EEEPROM to get it ready to accept a replacement key without having to replace the entire system. This can save you a lot of money.
