saab 9-3 key replacement Key Programming

saab 900 key cars that were built prior to 1994 feature an immobilizer mechanism based on coded keys. To add an additional key, you need an entirely new transponder and programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that it can be extremely expensive. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a key that has an electronic chip. This chip sends out a signal when the key is put in the ignition. The car will then check the signal to see whether it is the same as the one in the key. If the signals are identical, the car will unlock itself and begin. This is a great way to guard your car against theft.

Transponder keys could be an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. The metal part of the traditional key is easily cut and copied, whereas transponders are protected by an electronic chip that guards it. The chip has a unique code that is inserted into a car's computer order to identify it.

When a saab ignition key 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 an unmodified chip and programmed to match. Otherwise, the car would refuse to accept the key and will not start.

It is crucial to have a spare Saab key. This is especially important especially if you live in a rural area that is home to many car thieves. You can get a new key for your Saab by visiting the dealership without paying their expensive costs. You can have a replacement key created on the spot for less than half of what you would pay at an auto dealer.

Wired key

Saab cars are usually supplied with two keys. If you only own one, you need to purchase an extra key as soon as you can. This is because if the key is lost and the car needs a new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used vehicle.

The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project, and will require a lot of soldering. It's not a common way to do it, but you should determine how to get a saab replacement key to route and solder each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this, place a diode on each key switch pin and then solder it. This will shield the pins from current, and prevent them from being shorted. The diode will only allow current to flow in one direction, and it has a black band visual indicator that shows the direction in which 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 certain cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and guide the user through the process, making it easier than replacing the computer in the vehicle.

Jump starting the battery

The majority of people have a set in their trunks to jump start a car in an emergency, but it might not be the best option for vehicles with newer technology. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A voltage spike when a battery is hooked up to another can fry these components and render your vehicle undriveable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. 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 how to program saab 9-3 key fob a clean, unpainted metal surface underneath the disabled car's hood--the engine block is an excellent choice. Do not connect the black cable to the negative terminal on the dead battery because this could trigger an ignition spark that ignites the gasoline in the engine bay.

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. The battery in your Saab 9-3 will be recharged while you drive. It may take a while it to recharge again. You should consider purchasing a second key fob, as soon as possible. Replacing the only one that works requires the installation and programming of a new computer chip.

Replacement case

Many Saab owners have only one key for their car and if they lose it, key, it will cost them. The reason is that it's not inexpensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or any other catastrophe, it is best how to program saab 9-3 key fob have an extra key. Even it's "new", it will not work.

The dealer will charge you the most expensive dollar if you only have one working key. We can, however, reset and re-program your computer's EEPROM to accept the new key without having to replace the whole system. That can save you a significant amount of money. It's also a lot cheaper than waiting until you lose your sole key.
