saab key programmer Key Programming

Saab cars built since about 1994 feature an immobilizer mechanism made up of coded keys. A new transponder is required for addition of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

This can be expensive. This is the reason why you should always have a spare key on 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 if the signal matches the one on the key. If the signals are in sync it will unlock and begin. This is a fantastic way to guard your car against theft.

Transponder keys are an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal part of the traditional key is easily cut or copied, while transponders are protected by an electronic chip that guards it. This chip contains an unique code that is inserted into a car's computer in order to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car will only recognize the key fob if the device has an unmodified chip and has been programmed to match. The car won't start in the event that the key has not been programmed to match.

It is vital to have a spare saab 9-3 key fob replacement key. This is especially true when you live in a rural location where there are a lot of car burglars. The good news is that you can obtain a replacement key for your Saab without having to go to an auto dealership and pay the hefty prices that they demand. In the majority of instances, you can get an original key made on the spot for less than half the cost of what you would pay at a dealer.

Key for Wired

saab spare key cars typically come with two keys when they are new. If you have only one, it is an ideal idea to purchase an additional key fob as quickly as you can since if you lose it, your car will require a new CIM unit, and the locking cylinders have to be replaced. This can be expensive especially for cars that are used.

The next step is connecting the wires of columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There is no standard method to accomplish this, but it is crucial to plan How to program saab 9-3 key fob you will route and solder the rows and columns. For this keyboard, there are five 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 the key switches. To do this, you need to place a diode across each pin of the key switch and then solder it. This will protect the pins from current, preventing them from being cut off. A diode can only allow current to flow in one direction, and has a a black band visual indicator that shows the direction in which current will flow.

Some of the tools offered at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in certain cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and How to program saab 9-3 key fob guide the user through each step, making the process easier than replacing the car's computer.

Jump starting the battery

Most people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery on modern cars might not be the best option. These vehicles have many electronic devices and computers that communicate with each other. A surge in voltage when a battery is hooked up to another can fry these components and render your vehicle undriveable.

Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will say "POS" or "+".) Attach the other end to a clean unpainted metal surface beneath the hood of the disabled car. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery as it could ignite a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to recharge again. It's a good idea invest in a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and a special program to convince it that your lost keys aren't in the process of trying to steal the car.

Replacement Case

Many Saab owners only have one key for their vehicle and if they lose that they'll be charged. It's expensive to add an additional key and it requires replacing the CIM or TWICE for older models. It's recommended how to get a saab replacement key have a second key in the event of theft or other disaster and the best option is to purchase an extra key as early as you can. Even when the key is "new", it will not work.

The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and re-program the computer's EEPROM to accept a new key without replacing the whole system. This could save you lots of money. It's more affordable than wait until you loose the only key.
