Saab Key Programming

saab 9-3 key fob programming cars manufactured since 1994 feature an immobilizer system that is based on keys that are coded. A new transponder is required for addition of a second key, and special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

This can be expensive. It is recommended to always have a spare set of keys at hand.

Transponder key

The transponder key comes with an electronic chip that sends a signal back to the car when it is inserted into the ignition. The car then checks to see whether the signal is the same as the one on the key. If the signals are identical the car will be able to unlock itself and begin. This is an excellent way to protect your car from theft.

Transponder keys are a common feature in cars, but it is important to know that they are not as secure as classic metal keys. The metal component of the traditional key can easily be copied and cut, but transponders are protected by an electronic chip that safeguards it. The chip is equipped with a unique code programmed into the car's computer to identify it.

The car will recognize the Saab keyfob and allow it to turn on. However, it can only do this if the fob is equipped with a chip that is not modified that has been programmed to match. The car will not start if the key is not programmed to match.

It's essential to ensure that you have an extra key for your Saab. This is particularly true when you live in a rural location that has many car thieves. You can purchase a new key for your Saab by going to the dealership, without having to pay their pricey costs. You can get the replacement key on the spot for less than half of what you would spend at a dealership.

Wired key

Saab cars typically come with two keys when they are new. If you have only one, it's best to acquire an extra key fob as soon as you can as if you lose it the car will require the replacement of a CIM unit, and the locking cylinders will need to be replaced. This can be costly, especially for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. There's no standard way to do it, however, you should plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins from current, and prevent them from getting shorted. The diode will only allow the flow of current to be in one direction, and it also has a a black band visual indicator that shows the direction in which current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain instances programme replacement keys and recover the lost Saab key immobilizer's data, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

A lot of people keep a set in their trunk to jump-start a vehicle in an emergency, however it might not be the best idea for vehicles that are newer. These cars are equipped with a variety of electronic devices and computers that communicate with one another. A surge in voltage while a battery is hooked up to another can fry these components and render your vehicle unable to drive.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle that is disabled and let it run for approximately five minutes before disconnecting the cables in reverse order. Be aware that the battery in the Saab 9-3 gets recharged when you drive, so it could take a while to get the battery back to normal. It is recommended to purchase a second key fob, as soon as you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many Saab owners only have one key for their vehicle and if they lose it, it's going to cost them. 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 second key in case of theft or other disaster, and the best way is to purchase a second key as soon as you are able to. Even even if the key is "new" it will not work.

The majority of locksmiths won't be able to help with a single 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 EEEPROM of your computer to get it ready to accept a replacement key without having to replace the entire system. This could save you a lot of money. It's also cheaper than waiting until you lose your sole key.
