Saab Key Programming

saab ignition key cars manufactured since 1994 use an immobilizer that relies on key codes. In order to add a second key, it requires a new transponder and special programming. This is usually done at the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that this can be very expensive. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal to car when it is placed in the ignition. The car then checks to see whether the signal matches the one on the key. If both signals match the car will be able to unlock itself and start. This is a great method to stop auto theft and keep your vehicle secure from thieves.

Transponder keys are a common feature in cars, but it is important to know that they aren't as secure as traditional metal keys. While the metal portion of a traditional key could be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code encoded into the car's system to identify it.

When a saab spare key key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key is not programmed to match.

There isn't a standard way to accomplish this, however it's important to plan out the route you'll take and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin.

A diode can only allow current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.

Sanabria says that a few of the tools offered in auto parts stores, including the Autel MaxiIM IM608PRO or IM508 are able to assist shoppers or DIY customers to program replacement keys and restore immobilizer data. The tools connect to the OBD port and guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk for emergency situations, but jumping a battery on modern vehicles might not be the best option.

The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline inside the engine compartment.

The dealer will charge you the highest dollar if you only have one working key. However, we can reset and re-program the computer's EEPROM to prepare it to accept an alternative key without replacing the entire system. This can save you a great deal of money. It's cheaper to do this instead of waiting until you loose the only key.
