Saab Key Programming

Saab cars made since 1994 have an immobilizer system based on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. Always keep a spare set of keys at hand.

Transponder key

The transponder keys are keys with an electronic chip that transmits a signal to the car when it is put into the ignition. The car will check to see whether the signal matches the one on the key. If the signals match the car will be able to unlock itself and begin. This is a great way to prevent auto theft and keep your vehicle safe from thieves.

Transponder keys may be a popular addition to automobiles, but they are not as safe as traditional metal keys. While the metal part of a traditional key may be cut and copied, a transponder is protected by an electronic chip. The chip is equipped with a unique code that is programmed into the car's computer to identify it.

The car will recognize the saab 9-3 replacement key keyfob and allow it to turn on. The car can only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. Otherwise, the car will reject the key and refuse to start.

There is no standard method to accomplish this, however it is essential to determine the route you'll take and solder the rows and columns. There are 22 microcontroller wires as well as pins to connect to this keyboard. It includes 5 rows and 17 column.

After the columns and rows are soldered, it's the time to connect them to key switches. To do this, you need to place a diode over each pin of the key switch and then solder it. This will shield the pins from current and prevent them from getting shorted. A diode only allows the current to flow in a single direction, and it has an indicator of black color that indicates which way the current will flow.

Sanabria says that a few of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 can assist customers who are shopping or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jumpstarting the battery

A lot of people keep an assortment of tools in their trunk to jump start a car in an emergency, however it might not be the best option for vehicles with newer technology.
