Saab Key Programming

Saab cars produced since 1994 feature an immobilizer system that relies on coded keys. A new transponder is required for the addition of an additional key, as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The problem is that it can be very costly. It is recommended to always have a spare set of keys in your possession.

Transponder key

The transponder is a type of key that has an electronic chip. This chip sends a signal when the key is inserted into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a great way to protect your car from theft.

Transponder keys may be an extremely popular accessory for cars, but they are not as secure as traditional metal keys. The metal part of the traditional key is easily cut or copied, while transponders are protected by an electronic chip that safeguards it. The chip has a unique code that is inserted into a car's computers in order 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. The car will not start in the event that the key has not been programmed to match.

It's essential to ensure that you have an extra key for your Saab. This is particularly important if you live in a rural area, where there are a lot of car thieves. The good thing is that you can get a replacement key for your Saab without needing to visit a dealership and pay the hefty prices they ask. In most instances, you can get a brand new key made right on the spot at a fraction of the cost of what you would pay at the dealer.

Key for Wired

Saab cars are usually delivered with two keys. If you only own one, it is recommended to get an additional key as soon as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be costly particularly if you are buying a used car.

The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There's no standard way to accomplish this, however it is important to think about how to open a saab 93 without a key you will route and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 columns.

After the rows and column are soldered together after which it is time to connect the key switches. To do this, place a diode over each key switch pin and then solder it. This will shield the pins from current, preventing them from getting shorted. A diode lets current only flow in only one direction. It comes with a visual indicator, a black band, that indicates which direction current will flow.

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in some cases replace keys in the program and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.

Jump-starting the battery

The majority of people have the set in their trunks to jump-start their car in case of emergency, but this might not be a good option for vehicles with newer technology. These vehicles are equipped with computers and digital devices which communicate with each other. A voltage spike when the battery is connected another one could cause damage to the parts and render your vehicle unusable.

Start the working vehicle and allow it to run for approximately two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the affected car. The engine block is a great alternative. Do not connect the black cable to the negative terminal on the dead battery, as it could ignite a spark that ignites the gasoline in the engine bay.

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. Keep in mind that the battery on the Saab 9-3 will be charged when you drive, and it will take a while for the battery to come down. You should invest in another key fob as soon as possible. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement Case

saab Milton keynes owners usually only have one car key, and if that is lost, they will be charged. The reason is that it's costly to add 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 best to have a spare key. However, don't purchase a secondhand key even when it's "new." Keys that are claimed to be new from aftermarket sellers will not work and are likely to fail in the crucial moment.

The dealer will charge the highest dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to prepare it to accept the new key, without replacing the whole system. This could save you a lot of money. It's also a lot cheaper than waiting until you lose your sole key.
