saab key fob repair Key Programming

Saab cars manufactured since 1994 feature an immobilizer mechanism built on coded keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that this can be extremely expensive. Always keep a spare set of keys in your possession.

Transponder key

The transponder key comes with an electronic chip that sends a signal to car when it is inserted into ignition. The car is able to check if the signal matches the one on the key. If the signals match, the car will unlock and start. This is a great method to deter auto theft and keep your car secure from thieves.

Transponder keys are an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. The metal part of the traditional key can be easily cut or copied, while transponders have an electronic chip that safeguards it. The chip is a unique code that is inserted into a car's computer order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. However, it will only do this if the fob has a non-modified chip that has been programmed to match the original. The car won't start in the event that the key has not been programmed to match.

It's crucial to ensure that you have an extra key for your Saab. This is especially important for those who live in a rural area that is home to numerous car thieves. You can get a new key for your saab 9-3 key fob programming by going to the dealership, without having to pay their high costs. You can get the replacement key on the spot for less than half of what you would spend at a dealership.

Key for Wired

Saab cars are usually supplied with two keys. If you own only one, you should 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 purchasing a used vehicle.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most tedious part of the project and will require lots of soldering. It's not a standard way to go about it, but you need to determine how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, you need to place a diode across each key switch pin and solder it. This will protect the key switch pins from current and keep them from being shorted. The diode will only allow current to flow in one direction, and it comes with a an indicator in black that shows the direction in which current will flow.

Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even DIY customers in certain instances replace keys in the program and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep a set in their trunk to jump-start a car in an emergency, but it may not be the best option for vehicles with newer technology. These cars have a variety of computers and digital devices that communicate with one another. A voltage surge when the battery is connected to another can fry the components, rendering your car undriveable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the non-working one. 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 a clean, unpainted metal surface beneath the damaged vehicle's hood. An engine block is an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, start the vehicle you are not using and let it run for about five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 will be recharged while you drive. It will take a while for it to drop back down. It is a good idea to purchase a spare fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince the system that your lost keys aren't trying to steal the car.

Many Saab owners only have one key for their vehicle and if they lose it, they'll be charged. It's expensive to add keys and will require replacing the CIM or TWICE in the case of older models. It's recommended to have a spare key in case of theft or other disaster, and the best way is to purchase an additional key as soon as you are able to. However, don't purchase a secondhand key, even if it's "new." Keys that are claimed as new from a second-hand store will not work and are almost guaranteed to fail in the crucial moment.

The majority of locksmiths won't be able to help if you have only one working key, and the dealer will charge you high prices to replace the computer in your car to make a replacement. We can reset and reprogram the computer's EEEPROM to make it ready to accept a new key without the need to replace the entire system. This could save you a significant amount of money. It's also much less expensive than waiting until you lose the only key.
