saab key fob Repair Key Programming

saab keys cars made since 1994 feature an immobilizer system based on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer with a specialized Tech2 diagnostic tool.

The issue is that it can be very expensive. It is always advisable to keep an extra set of keys at hand.

Transponder key

The transponder is a type of key that is equipped with an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car then checks to see whether the signal matches the one on the key. If the signals are in sync the car will then open and start. This is a great method to avoid car theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature in automobiles, but you must be aware that they are not as secure as traditional keys made of metal. The metal component of the traditional key is easily cut and copied, however transponders are protected by an electronic chip that guards it. The chip has a unique code which is programmed into a car's computer in order to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. However, it can only do so if the key fob is unmodified and has a chip that has been programmed to match. In the absence of that, the car will reject the key and won't start.

The good thing is that you can find a new key for your saab replacement key programming without needing to visit a dealer and pay the hefty prices that they ask.

The next step is connecting the wires of columns and row to your microcontroller. This is the toughest part of the project, and it will require lots of soldering. It's not a common way to go about it, but you need to consider how you will route and solder each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together after which it is time to connect the key switches. To do this, you need to place a diode across each pin of the key switch and solder it. This will protect the pins from current and prevent them from being cut off. A diode lets current 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 some of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO or IM508 will assist shoppers or DIY customers to program replacement keys and restore the immobilizer's data. The tools plug into 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 for emergency situations, but jumping a battery in newer vehicles may not be the best choice. These vehicles are equipped with many computers and digital devices which communicate with one another. A surge in voltage while the battery is connected to another could cause damage to these components, rendering your vehicle undriveable.

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

Replacement Case

Saab owners usually have only one car key, and if it is lost saab keys, they'll be charged. The reason for this is that it's costly to purchase 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 calamity it is recommended to have an extra key. Don't purchase a used key, even it's "new." Keys that are claimed to be new from a second-hand store will not be effective and are almost guaranteed to fail in the most critical moment.

Most locksmiths cannot help you when you only have one working key, and the dealer will charge you high prices to replace the computer in your car to create a replacement.
