saab 9-3 key replacement Key Programming

saab Ignition key replacement cars that were built prior to 1994 have an immobilizer feature based on coded keys. A new transponder is required in order to enable the addition of a second key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

This can be expensive. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder key is a key with an electronic chip that sends a signal back to the car when it is put into the ignition. The car then examines the signal to see whether it is the same as that of the key. If the signals match it will unlock and start. This is a fantastic way to guard your car against theft.

Transponder keys are a popular feature in automobiles, but it is important to know that they aren't as secure as traditional keys made of metal. While the metal part of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip has a unique code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob and allow it to turn on. The car can only recognize the key fob if the device has an unmodified chip and has been programmed to match. If not, the car will refuse to accept the key and will not start.

There's no standard way to do it, but you need to consider how you will 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 the key switches. To do this, put a diode across each pin on the key switch and then solder it. This will shield the pins from current, thus preventing them from being shorted. A diode permits current to only flow in only one direction. It comes with a visual indicator, a black band, that shows which way current will flow.

Sanabria states that a number of the tools available in auto parts stores, such as the Autel MaxiIM IM608PRO and IM508 are able to assist customers who are shopping or DIY users to program replacement keys and restore immobilizer information. The tools connect to OBD ports and help the customer through each step and make the process more straightforward than replacing the vehicle's computer.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk in case of emergency however, jumping a battery on modern cars might not be the best idea. These cars have a variety of electronic devices and computers that communicate with one another. A voltage surge when batteries are connected to another battery could damage the components making your car unusable.

Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood--the engine block is a good option. Do not connect the black cable to the negative terminal on the dead battery, as this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle that is disabled and allow it to run for around five minutes before you disconnect them in reverse order. Be aware that the battery of your saab key replacement cost 9-3 is recharged when you drive, so it can take a while to get the battery back to its original level. It's a good idea invest in a spare key fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and special programming to convince the system that your lost keys are not trying to steal the car.
