Saab Key Programming

saab 9-5 key replacement cars that were built prior to 1994 feature an immobilizer mechanism built on coded keys. To add an additional key, you need a new transponder and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The transponder is a type of key that has an electronic chip. This chip sends out a signal when the key is put into the ignition.

There isn't a standard method to do it, but you need to determine how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this you must place a diode across each key switch pin and then solder it. This will protect the pins from current, preventing them from being cut off. A diode allows the flow of current to be in one direction, and it comes with a the black band as a visual indicator that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or saab Fob key Replacement DIY customers in certain instances program replacement saab car keys keys and restore lost immobilizer data Sanabria says.
