Saab Key Programming

Saab cars manufactured since 1994 feature an immobilizer that relies on a set of keys. Adding an extra key requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

This can be expensive. This is the reason why you should always have a spare key available.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal back to the car when it is put into the ignition. The car is able to check if the signal matches the one on the key. If the signals match, the car will unlock itself and begin. This is an excellent way to protect your vehicle from theft.

Transponder keys are an extremely popular accessory for cars, but they are not as safe as traditional metal keys. While the metal part of a traditional key can be cut and copied the transponder is protected by an electronic chip. This chip has an individual code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. If not, the car will reject the key and refuse to start.

It is vital to have an extra Saab key. This is particularly important especially if you reside in a rural area where there are numerous car thieves. The good news is that you can find a replacement key for saab 93 key to your Saab without needing to visit an auto dealer and pay the high costs that they charge. You can have a replacement key created on the spot for less than half the cost you would pay at dealerships.

Wired key

saab replacement key programming cars usually come with two keys when they're new. If you only have one, it is an ideal idea to purchase an extra key fob as soon as is possible since if you lose it, your car will require a new CIM unit, and the locking cylinders will have to be replaced. This can be costly especially for used vehicles.

The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and will require a great deal of soldering. It's not a common way to do it, but you need to consider how to get a saab replacement key you will connect and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It includes 5 rows and 17 columns.

After the columns and rows are soldered together It is now time to connect the key switches. To do this you must place a diode across each pin on the key switch and then solder it. This will shield the key switch pins from current and stop them from being shorted. A diode allows the current to flow in a single direction, and it also has a an indicator in black that indicates 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 -- could assist customers at the shop or DIY customers in certain instances replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk for emergencies, but jumping a battery for newer vehicles might not be the best idea. These vehicles are equipped with numerous electronic devices and computers that communicate with each other. A voltage spike when the battery is connected another battery could damage the components and render your vehicle unusable.

Start the working vehicle and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean unpainted metal surface underneath the hood of your disabled vehicle. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal on the dead battery because this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, turn on the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Keep in mind that the battery on your Saab 9-3 is recharged while you drive, so it may take some time to get the battery back to its original level. It's a good idea invest in a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince the system that your lost saab keys keys are not trying to steal the car.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose that they'll be charged. The reason is that it's costly to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft, or other catastrophe it is best to have a spare key. Even even if the key is "new" it won't work.

The dealer will charge you top dollar if you only have one working key. However, we can reset and reprogram the computer's EEPROM to prepare it to accept the new key without having to replace the entire system. This can save you a significant amount of money. It's also cheaper than waiting until you lose the only key.
