saab 93 replacement key Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that relies on key codes. A new transponder is required for addition of an extra key, and special programming. This is usually done at the dealer using a special Tech2 diagnostic tool.

It can be costly. It is always advisable to keep an extra set of keys at hand.

Transponder key

The transponder is a piece of key equipped with an electronic chip. The chip transmits a signal when the key is put in the ignition. The car will then check the signal to determine whether it is identical to the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a great method to prevent auto theft and keep your vehicle safe from thieves.

Transponder keys are a common feature in automobiles, however you should be aware they are not as secure as traditional metal keys. The metal component of a traditional key can easily be copied and cut, but transponders are protected by an electronic chip that protects it. The chip has an unique code that is embedded into the car's computer to identify it.

The car will recognize the Saab keyfob and allow it to turn on. However, it can only do this if the key fob has a non-modified chip that has been programmed to match the original. The car will not start in the event that the key has not been programmed to match.

It is vital to have a spare Saab key. This is especially true if you reside in a rural location that has many car thieves. You can purchase a new key for your saab keys replacement by visiting the dealership and not paying their expensive cost. You can get a replacement key created on the spot for less than half of the price you'd spend at the dealership.

Key for Wired

Saab cars are usually delivered with two keys. If you only own one, you should get an extra key as soon as you can. This is because if you lose it and the car needs a new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.

The next step is to connect the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a good deal of soldering. There isn't a standard method to do it, but you should consider how you will connect 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.

After the columns and rows are soldered, it's the time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins from current, and prevent them from being shortened. The diode will only allow the flow of current to be in one direction, and it also has a an indicator of black color that shows the direction in which current will flow.

Sanabria states that a number of the tools offered in auto parts stores, such as the Autel MaxiIM IMM608PRO and Saab Spare key IM508 can assist customers who are shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jumpstarting the battery

A lot of people keep a set of jumper cables in their trunk in case of emergency, but jumping a battery in newer automobiles might not be the most efficient option. These vehicles are equipped with a number of electronic devices and computers that communicate with each other. A surge of voltage when batteries are connected to another can fry the components and render your vehicle unusable.

Start the vehicle that is working and let it run for about two minutes before connecting the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface beneath the damaged car's hood--the engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, start the vehicle that has been disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 will recharge as you drive. It may take a while it to recharge again. It's a good idea to purchase a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't trying to steal the car.

Many Saab owners have only one key for their vehicle and if they lose that it's going to cost them. The reason is that it's expensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in case of theft or other disaster the best solution is to purchase an additional key as early as you can. But don't buy a used key even it's "new." Keys that are claimed to be new from sellers selling aftermarket keys won't work and are likely to fail at the crucial moment.

The dealer will charge you the most expensive dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to make it ready to accept a replacement key without the need to replace the entire system. This can save you lots of money. It's also a lot cheaper than waiting until you lose the only key.
