saab car keys Key Programming

Saab cars built since about 1994 feature an immobilizer mechanism built on coded keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

It can be costly. This is why it is important to always keep a spare key in your possession.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to the car when it is put into the ignition. The car will check to see whether the signal matches the one on the key. If the signals match then the car will be able to unlock and begin. This is a great method to prevent auto theft and keep your vehicle safe from thieves.

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 can be cut and copied however, a transponder is secured by an electronic chip. This chip has an individual code that is embedded into the car's computer to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. However, Saab Ignition Key Replacement it is only able to do so if the key fob is equipped with a chip that is not modified that has been programmed to match it. In the absence of that, the car will refuse to accept the key and will not start.

It is crucial to have a spare saab key fob key. This is especially true especially if you reside in a rural region where there are numerous car thieves. The good part is that you can find a new key for your Saab without having to go to an auto dealership and pay the high costs that they ask. In the majority of instances, you can get an original key made on the spot at a fraction of the price of what you would pay at the dealer.

Wired key

Saab ignition key replacement cars usually come with two keys when they are new. If you have only one, it is best to acquire an additional key fob as soon as possible in case you lose it, your car will require an entirely new CIM unit, and the locking cylinders need to be replaced. This could be expensive especially if purchasing a used car.

The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a large amount of soldering. There's no standard way to go about it, but you should plan how to route and solder each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered together after which it is time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins of the key switch from current and also prevent them from being shorted. The diode will only allow the flow of current to be in one direction, and it has the black band as a visual indicator that shows the direction in which current will flow.

Some of the tools you can find 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 the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer inside the vehicle.

Jump-starting the battery

Most people keep the set in their trunk to jump-start a car in an emergency, but this might not be a good idea for vehicles that are newer. They have numerous digital and electronic devices that communicate with one another. A surge in voltage when batteries are connected to another could cause damage to the components and render your vehicle unusable.

Start the vehicle you are using and allow it to run for saab Ignition Key replacement approximately two minutes before connecting the cables to the non-working one. 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 of the black cable to an unpainted, clean metal surface underneath the car's hood--the engine block is an ideal choice. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline inside the engine compartment.

Once the cables are connected, you should start the car and allow it to run for around five minutes. Then, disconnect them in reverse. Be aware that the battery in the Saab 9-3 gets recharged during your drive, which means it will take a while for the battery to go back to its original level. You should consider purchasing another key fob as soon as you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Replacement case

Saab owners usually only have one car key, and if that is lost, they will be charged. The reason is that it's not cheap to replace a key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or any other calamity it is recommended to have an extra key. Even even if the key is "new" it won't work.

The majority of locksmiths won't be able to help when you only have one working key, and the dealer will charge high prices to replace the computer in your vehicle for a replacement. We can, however, reset and re-program the computer's EEPROM in order to prepare it to accept the new key without having to replace the whole system. That can save you lots of money. It's also a lot cheaper than waiting until you lose your sole key.
