saab 9-3 key Key Programming

saab ignition Key cars made since 1994 feature an immobilizer mechanism based on coded keys. Adding an extra key requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. You should always keep an extra set of keys on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are the same it will open itself and begin. This is a great method to protect your vehicle from theft.

Transponder keys could be an increasingly popular feature for cars, but they're not as secure as traditional metal keys. While the metal portion of a traditional key may be cut and copied, a transponder is protected by an electronic chip. This chip contains an individual code that is programmed into the car's computers to identify it.

The car will recognize the saab 93 key keyfob and allow it to be turned on. The car can only recognize the key fob when it has an unmodified chip and has been programmed to match. Otherwise, the car will reject the key and won't start.

It's important to make sure that you have a spare key for your Saab. This is especially important when you live in a rural location where there are numerous car thieves. You can get a new key for your Saab by going to the dealership and not paying their high costs. You can get a replacement key created on the spot for less than half of the price you'd spend at a dealership.

Wired key

saab 93 key fob replacement cars are usually delivered with two keys. If you only own one, you should get an additional key as quickly as you can. This is because if the key is lost and the car needs an entirely new CIM and the locking cylinders replaced. This could be expensive especially if you're purchasing a used car.

The next step is connecting the wires of columns and row to your microcontroller. This is the most laborious component of the project and it will require a lot of soldering. There isn't a standard way to do this, but it is crucial to plan the route you'll take and solder the rows and columns. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are joined It is now time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and keep them from being shorted. The diode allows current to only flow in one direction. It has a visual indicator that is black, that shows the direction in which the current will flow.

A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 PRO and IM508 -- may aid shop customers or DIY customers in certain instances replace keys in the program and restore lost immobilizer data, Sanabria says. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the car's computer.

Jump starting the battery

A majority of people keep the set in their trunks to start a vehicle in an emergency, but it might not be the best idea for vehicles that are newer. These cars are equipped with a variety of digital and computer systems that communicate with one another. A surge of voltage when the battery is connected to another battery could damage the components making your car unusable.

Start the vehicle that is working and let it run for about two minutes before you connect the cables to the battery that is not working. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the car's hood. The engine block would be an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause sparks that could ignite the gasoline inside the engine compartment.

Once the cables are connected, turn on the vehicle that has been disabled and allow it to run for around five minutes before you disconnect them in reverse order. The battery in your saab key battery 9-3 will recharge as you drive. It will take a while for it to fall back. It's a good idea invest in a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince it that your missing keys aren't in the process of trying to steal the car.

Replacement Case

Many Saab owners have only one key for their vehicle and if they lose it, it's going to cost them. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. In the event of theft or any other disaster it is best to have a spare key. However, don't purchase a secondhand key, even the case that it's "new." Keys that are claimed to be new from aftermarket sellers will not perform and are almost certain to fail at the crucial moment.

The dealer will charge you top dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key for saab 93 key without the need to replace the entire system. This could save you a great deal of money. It's much cheaper than wait until you loose the only key.
