Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer feature based on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

The problem is that this can be very expensive. This is why it is important to always have a spare key on hand.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. The chip transmits a signal when the key is placed in the ignition. The car checks to see whether the signal matches with the one on the key. If the signals are the same the car will then unlock itself and begin. This is a great way to prevent auto theft and keep your car secure from thieves.

Transponder keys could be an increasingly popular feature for cars, but they're not as safe as traditional keys made of metal. While the metal parts of a traditional key can be cut and copied the transponder is protected by an electronic chip. The chip has a unique code that is inserted into a car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car can only recognize the key fob if it is equipped with an unmodified chip and programmed to match. Otherwise, the car will reject the key and not start.

It is essential to ensure that you have a spare key for your saab ignition key replacement. This is particularly important especially if you live in a rural area with many car thieves. You can obtain a replacement key for your Saab by visiting the dealership, without having to pay their expensive costs. You can get the replacement key on the spot at a fraction of the price you'd spend at the dealership.

Key for Wired

Saab cars typically come with two keys when they're new. If you have only one, you should get an additional key as fast as you can. This is because if the key is lost, the car will need a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

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 requires a significant deal of soldering. There isn't a standard way to accomplish this, however it is crucial to plan how to get a saab replacement key you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns. This means 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 the key switches. To do this you must place an inverter over each key switch pin and solder it. This will protect the pins that are used for key switches from current and prevent them from being shorted. The diode allows current to only flow in only one direction. It features a visual indicator of a black line that shows which way current will flow.

Some of the tools offered at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- can help customers in the shop, or even DIY users in some cases programme replacement keys and recover the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the user through each step making the process simpler than replacing the car's computer.

Jump-starting the battery

A majority of people keep the set in their trunks to jump start a car in an emergency, however it might not be the best option for saab Key programming vehicles with newer technology. These vehicles are equipped with numerous electronic devices and computers that communicate with one another. A surge in voltage while the battery is connected to another one could damage the components and render your car unable to drive.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block would be a good option. Don't connect the black cable to the negative terminal on the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run for about five minutes. Then disconnect the cables in reverse. Be aware that the battery of your Saab 9-3 is recharged when you drive, and it can take a while to get the battery back to normal. It's a good idea to purchase a spare key fob as soon as you can, since replacing the only functioning one 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

Saab owners usually have only one car key, and if it is lost, they will be charged. It's costly to add the key and also requires replacing the CIM or TWICE for older models. In the event of theft, or any other catastrophe it is advisable to have a spare key. Don't purchase a used key, even it's "new." Keys that are claimed-new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the most critical moment.

Most locksmiths cannot help you if you have only one working key and the dealer will charge high prices to replace the computer in your vehicle to make a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This could save you lots of money. It's less expensive rather than wait until you lose the only key.
