The problem is that this can be very costly. It is recommended to always have an extra set of keys on hand.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends out a signal when the key is put in the ignition.

There is no standardized way to accomplish this, however it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. To do this you must place a diode over each key switch pin and solder it. This will shield the pins from current, thus preventing them from being shorted. A diode can only allow the current to flow in a single direction, and has a a black band visual indicator that indicates which way the current will flow.

A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in certain cases replace keys in the program and restore lost saab key immobilizer data Sanabria says.
