saab fob key replacement Key Programming

Saab cars made since 1994 feature an immobilizer mechanism built on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using the Tech2 diagnostic tool.

This can be expensive. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder key is a piece of hardware with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car then checks the signal to determine if it matches the one on the key. If the signals match, saab key fob Repair the car will unlock and begin. This is a great way to stop auto theft and keep your vehicle safe from thieves.

Transponder keys are a favored feature in cars, but you must be aware that they aren't as secure as classic metal keys. While the metal component of a traditional key may be cut and Saab Key Fob Repair copied, a transponder is protected by an electronic chip. This chip has a unique code encoded into the car's system to identify it.

The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob if the device has an unmodified chip and programmed to match. The car will not start in the event that the key is not programmed to match.

It is crucial to have an extra Saab key. This is especially important for those who live in a rural region where there are a lot of car thieves. The good thing is that you can find a new key for your Saab without needing to visit an auto dealer and pay the expensive prices that they ask. You can get an original key made on the spot at a fraction of the price you'd pay at dealerships.

Wired key

Saab cars are typically delivered with two keys. If you only have one, it's a good idea to get an extra key fob as soon as you can, because if you lose it, your car will require an entirely new CIM unit and the locking cylinders have to be replaced. This could be expensive especially if purchasing a used car.

The next step is to connect the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There's no standard way to go about it, but you must think about how to route and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the rows and column are joined, it is time to connect the key switches. To do this, place a diode across each pin on the key switch and solder it. This will shield the pins from current, thus preventing them from getting shorted. A diode can only allow the flow of current to be in one direction, and has a an indicator in black that indicates the direction current will flow.

Some of the tools available at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY customers in certain cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk for emergencies however, jumping a battery on modern cars might not be the best choice. These vehicles are equipped with many digital and computers that communicate with one another. A surge in voltage while a battery is hooked up to another battery could fry the components and render your car unable to drive.

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 of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface underneath the hood of your disabled car. The engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery, as it could ignite an ignition that ignites the gasoline in the engine bay.

Once the cables are connected, start the disabled vehicle and let it run for about five minutes before you disconnect them in reverse order. Remember that the battery on your saab key fob repair 9-3 is recharged when you drive, and it can take a while to get the battery down. It is a good idea to purchase a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that your lost keys are not trying to steal the car.

Replacement Case

Many Saab owners only have one key for their car and if they lose it, the cost will be. It's expensive to add an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a second key in case of theft or any other catastrophe and the best option is to buy an extra key as soon as you can. Even it's "new", it will not work.

The dealer will charge you top dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without having to replace the entire system. This could help you save money. It's also cheaper than waiting until you lose your only key.
