saab key replacement cost Key Programming

Saab cars made since 1994 have an immobilizer system made up of coded keys. A new transponder is required for the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

This can be expensive. It is always advisable to keep an extra set of keys in your possession.

Transponder key

The transponder is a piece of key that has an electronic chip. The chip transmits a signal when the key is put into the ignition. The car then checks the signal to determine whether it is identical to the one in the key. If the signals are the same the car will then unlock itself and begin. This is a great method to stop auto theft and keep your car secure from thieves.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as safe as traditional keys made of metal. While the metal parts of a traditional key may be cut and copied the transponder is protected by an electronic chip. This chip contains an individual code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. But, it's only able to do so if the key fob has an unmodified chip that has been programmed to match. Otherwise, the car will reject the key and not start.

It is important to have an extra Saab key. This is especially important for those who live in a rural region that has numerous car thieves. You can get a new key for your saab 93 key fob replacement by going to the dealership, without having to pay their expensive cost. You can have an original key made on the spot for less than half of the price you'd pay at an auto dealer.

Wired key

Saab cars usually come with two keys when they are new. If you only have one, it is recommended to purchase an extra key fob as soon as you can, because if you lose it, the car will require a new CIM unit and the locking cylinders will need to be replaced. This can be expensive particularly for used cars.

The next step is to connect the row and column wires to the microcontroller. This is the most challenging part of the project and requires a significant deal of soldering. It's not a common way to go about it, but you need to plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined after which it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins from current, thus preventing them from being shortened. A diode allows current to only flow in only one direction. It has a visual indicator that is black, that shows the direction in which the current will flow.

Some of the tools you can find at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or [Redirect-302] DIY customers in some cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and guide the user through the process, making it more simple than replacing the computer inside the vehicle.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunks for emergency situations, but jumping a battery for newer automobiles might not be the best idea. These cars have a variety of digital and computer systems that communicate with each other. A surge in voltage while the battery is connected to another one could damage these components, rendering your vehicle undriveable.

Start the working vehicle and allow it to run for around two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could create a spark, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, you can start the disabled vehicle and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in the saab spare key 9-3 will charge while you drive. It will take some time for it to recharge again. It is recommended to purchase an additional 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 usually only have one car key, and if that is lost, they'll be charged. It's costly to add keys and will require replacing the CIM or TWICE for older models. It is best to have a spare key in case of theft or other disaster, and the best way is to purchase an additional key as soon as you can. However, don't purchase a secondhand key, even when it's "new." Keys that are claimed-new from sellers selling aftermarket keys won't work and are likely to fail at the crucial moment.

The dealer will charge you the highest 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 without replacing the entire system. This can help you save money. It's more affordable than wait until you lose the only key.
