saab car key replacement Key Programming

saab replacement key programming cars made since 1994 use an immobilizer that relies on key codes. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

The issue is that it can be extremely expensive. You should always keep a spare set of keys at hand.

Transponder key

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

Transponder keys may be an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. The metal part of the traditional key can be easily cut and copied, however transponders are protected by an electronic chip that safeguards it. The chip contains a unique code that is programmed into a car's computers in order to identify it.

The car will recognize the saab keys replacement keyfob and allow it to be turned on. However, it can only do this if the key fob is equipped with a chip that is not modified that has been programmed to match it. The car will not start in the event that the key is not programmed to match.

It's important to make sure that you have a spare key for your Saab. This is especially true especially if you reside in a rural area, where there are a lot of car burglars. The good part is that you can obtain a replacement saab 9-3 key key for your Saab without having to go to an auto dealership and pay the expensive prices that they ask. You can have a replacement key created on the spot for less than half of what you would spend at the dealership.

Wired key

Saab cars are usually provided with two keys. If you have only one, it's an ideal idea to purchase an extra key fob as soon as you can as if you lose it the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be expensive especially for used vehicles.

The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a good amount of soldering. It's not a common way to do it, but you need to consider how you will route and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins that are used for key switches from current and stop them from being shorted. A diode can only allow the flow of current to be in one direction, and it also has a the black band as a visual indicator that shows the direction in which current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help shop customers or even DIY customers in certain cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and guide the user through the procedure, making it much easier than replacing the computer in the vehicle.

Jump starting the battery

The majority of people have a set in their trunks to start a vehicle in the event of an emergency, but this might not be the best idea for newer cars. These vehicles are equipped with numerous computers and digital devices which communicate with each other. A surge of voltage when a battery is connected to another can fry the components and render your vehicle unusable.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface beneath the hood of the disabled car. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks, which could ignite gasoline in the engine compartment.

Once the cables are connected, you can start the vehicle that is disabled and let it run for about five minutes before disconnecting them in reverse order. The battery in the saab 9-3 key replacement 9-3 will charge as you drive. It will take some time for it to recharge again. You should invest in a second key fob, when you can. The replacement of the one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners typically only have one car key, and if that is lost, they'll be charged. It's expensive to purchase a key and requires replacing the CIM or TWICE for older models. It's recommended to have a spare key in case of theft or other disaster, and the best way is to purchase an extra key as soon as you are able to. Even when the key is "new" it will not function.

The dealer will charge you top dollars if you only have one working key. However, we can reset and reprogram the computer's EEPROM to accept the new key, without replacing the entire system. This can save you a great deal of money. It's much cheaper instead of waiting until you lose the only key.
