Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer system built on coded keys. A new transponder is required for the addition of an extra key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that it can be very costly. This is why you should always have a spare key available.

Transponder key

The transponder can be described as a key that has an electronic chip. This chip sends a signal when the key is placed in the ignition. The car will then check the signal to see whether it matches the one that is in the key. If the signals match then the car will be able to open and start. This is a great way to deter car theft and keep your vehicle safe from thieves.

Transponder keys could be a popular addition to automobiles, but they are not as secure as traditional metal keys. While the metal portion of a traditional key could be cut and copied, a transponder is protected by an electronic chip. This chip contains a 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. But, it's only able to do this if your key fob is equipped with a chip that is not modified that has been programmed to match. Otherwise, the car would reject the key and not start.

It's essential to ensure that you have a spare key for your saab replacement keys uk. This is especially true especially if you live in a rural area that is home to many car thieves. The good thing is that you can find a replacement key to your Saab without having to go to an auto dealership and pay the high prices that they ask. You can get an original key made on the spot for less than half the price you'd pay at the dealership.

Key for Wired

saab 9-3 key cars are typically delivered with two keys. If you only have one, you should purchase an additional key as fast as you can. This is because if you lose it the car will require a New Car Key cost CIM and the locking cylinders replaced. This can be costly especially if buying a used car.

The next step is to wire the column and row wires to the microcontroller. This is the most difficult part of the project and will require a good deal of soldering. It's not a standard way to do it, but you need to consider how you will route and solder each column and row. There are 22 microcontroller wires and pins that you can connect to this keyboard. It has 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, put a diode across each pin on the key switch and solder it. This will shield the pins of the key switch from current and keep them from being shorted. A diode lets current only flow in only one direction. It comes with a visual indicator that is black, that shows which way current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- may help customers in the shop, or even DIY customers in certain instances program replacement keys and restore lost immobilizer data Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery on newer vehicles might not be the best idea. These vehicles are equipped with many digital and computers that communicate with one another. A surge in voltage while the battery is connected to another can fry the components and render your vehicle undriveable.

Start the vehicle that is working and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the disabled car. The engine block is a great alternative. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite gasoline in the engine compartment.

Once the cables are connected, start the vehicle and let it run about five minutes. Then, disconnect them in reverse. Be aware that the battery of your Saab 9-3 is recharged when you drive, and it may take some time for the battery to come back down again. It is a good idea to purchase a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and a special program to convince it that your missing keys are not trying to steal the car.

Replacement Case

Saab owners typically only have one car key, and if it is lost, they will be charged. The reason is that it's expensive to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is best to have a spare key in case of theft or any other catastrophe the best solution is to purchase an extra key as soon as you are able to. Even it's "new", it won't work.

The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without having to replace the entire system. This could help you save money. It's less expensive rather than wait until you lose your only key.
