Saab Key Programming

saab ignition key cars built since about 1994 feature an immobilizer mechanism that is based on codes for keys. A new transponder is required in order to enable the inclusion of an additional key, and special programming. This is usually done by the dealer, using a specially-designed Tech2 diagnostic tool.

The issue is that it can be quite costly. It is recommended to always have an extra set of keys in your possession.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is inserted into the ignition. The car checks to see whether the signal matches the one on the key. If the signals match, the car will unlock itself and begin. This is an excellent way to safeguard your car from theft.

Transponder keys are a common feature in vehicles, but you should be aware that they're not as secure as classic keys made of metal. While the metal parts of a traditional key can be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code that is embedded into the car's computer to identify it.

The car will recognize the saab key fob repair keyfob and permit it to turn on. However, it is only able to do this if the fob has a non-modified chip that has been programmed to match the original. In the absence of that, the car will refuse to accept the key and will not start.

This is because if the key is lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.

The next step is to connect the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There's no standard way to do it, but you must plan 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.

After the rows and column are joined, it is time to connect the key switches. To do this you must place a diode across each key switch pin and solder it. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator, a black band, that indicates the direction in which current will flow.

Sanabria states that a number of the tools offered in auto parts stores, including the Autel MaxiIM IMM608PRO and IM508 can assist customers who are shopping or DIY customers to program replacement keys and restore immobilizer information. The tools connect to OBD ports and guide the customer through each step which makes the process much easier than replacing the vehicle's computer.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk to use in an emergency however, jumping a battery on newer automobiles might not be the best idea.

Attach the other end to a clean, unpainted metal surface underneath the hood of your disabled vehicle. The engine block is an excellent option. Do not connect the black cable to the negative terminal on the dead battery, as this could trigger an ignition spark that ignites the gasoline in the engine bay.

Replacement case

Many Saab owners only have one key for their car and if they lose that the cost will be. The reason for this is that it's not cheap to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other catastrophe it is recommended to have an extra key. Even when the key is "new", it won't work.

The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the EEEPROM of your computer to get it ready to accept a new key without the need to replace the entire system. This could save you a lot of money.
