saab 9-3 key not accepted contact service Key Programming

Saab cars manufactured since 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required to allow the addition of a second key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that it can be extremely expensive. This is why it is important to always have a spare key available.

Transponder key

The transponder key comes with an electronic chip that sends a signal back to the car when it is placed in the ignition. The car then checks the signal to see whether it is identical to the one that is in the key. If the signals match the car will then open and start. This is a great way to stop auto theft and keep your vehicle secure from thieves.

Transponder keys are an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. While the metal parts of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code which is programmed into a car's computer in order to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. The car won't start if the key is not programmed to match.

The next step is to connect the wires for the column and row to the microcontroller. This is the most difficult aspect of the project and it will require a lot of soldering. It's not a standard way to go about it, but you should plan how to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's the time to connect them to key switches. To do this, put a diode over each key switch pin and solder it. This will shield the pins on the key switch from current and prevent them from being shorted. A diode permits current to only flow in one direction. It features a visual indicator that is black, that shows which way current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IMM608PRO and IM508 will assist customers who are shopping or DIY users to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep a few sets of jumper cables in their trunk to use in an emergency, but jumping a battery in newer automobiles might not be the best option. These cars have a variety of digital and computer systems that communicate with one another. A voltage surge while a battery is hooked up to another could cause damage to these components, rendering your car unable to drive.

Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block would be a good choice. Do not connect the black cable to the negative terminal on the dead battery, since this could trigger an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, turn on the vehicle that has been disabled and let it run for approximately five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 will be recharged while you drive. It takes a while for it to return to its original state. It's a good idea purchase a spare fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and saab spare key a special program to convince it that your lost keys aren't in the process of trying to steal the car.

Replacement case

Many saab spare key (simply click the up coming site) owners have only one key for their vehicle and if they lose it, the cost will be. The reason for this is that it's not inexpensive to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a spare key in the event of theft or any other catastrophe, and the best way is to purchase a second key as soon as you are able to. Don't buy a secondhand key, even it's "new." Keys that are claimed as new from aftermarket sellers will not work and are almost guaranteed to fail in the crucial moment.

The dealer will charge the highest dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without having to replace the entire system. This can save you a lot of money. It's less expensive instead of waiting until you lose the sole key.
