saab 9-5 key replacement cars manufactured since 1994 feature an immobilizer mechanism made up of coded keys. The addition of a key requires a new transponder and special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

It can be costly. This is why it is important to always have a spare key available.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is put into the ignition. The car then checks to see if the signal matches the one on the key.

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's no standard way to do it, but you should plan how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together, it is time to connect the key switches. To do this, place a diode across each pin on the key switch and solder it. This will protect the pins on the key switch from current and prevent them from being shorted. The diode will only allow the current to flow in a single direction, and it has a black band visual indicator that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- could help shop customers or even DIY customers in some cases create replacement keys and restore the lost saab key immobilizer's data, Sanabria says.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery for newer automobiles might not be the best choice.

(It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled vehicle's hood. An engine block is an ideal choice. Do not connect the black cable to the negative terminal on the dead battery, as this could trigger an ignition source that ignites gasoline in the engine bay.

Many saab Ignition key owners have only one key for their vehicle and if they lose it, key, it will cost them. The reason for this is that it's expensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft or any other catastrophe it is recommended to have an extra key. Even it's "new", it will not function.
