saab 93 replacement key Key Programming

Saab cars made since 1994 utilize an immobilizer system based on key codes. A new transponder is required to allow the addition of an additional key, and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys available.

Transponder key

The transponder is a type of key equipped with an electronic chip. This chip sends a signal when the key is put into the ignition. The car then examines the signal to determine whether it is identical to the one on the key. If the signals match the car will then unlock itself and begin. This is a great method to guard your car against theft.

Transponder keys may be an extremely popular accessory for cars, but they are not as safe as traditional metal keys. While the metal portion of a traditional key can be cut and copied the transponder is protected by an electronic chip. The chip has an unique code that is embedded into the car's computer to identify it.

When a Saab key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if it has an unmodified chip and programmed to match. Otherwise, the car would reject the key and refuse to start.

It is crucial to have a spare saab replacement Key programming key. This is particularly important if you reside in a rural area with many car thieves. The good thing is that you can find a new key for your Saab without needing to visit an auto dealer and pay the high prices that they ask. You can get a replacement saab 9-3 key key made on the spot for less than half of the price you'd spend at a dealership.

Wired key

saab key programmer cars typically come with two keys when they are new. If you only have one, you should purchase an additional key as quickly as you can. This is because if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.

The next step is to connect the column and row wires to the microcontroller. This is the toughest aspect of the project and will require lots of soldering. There's no standard way to go about it, but you must plan how to get a saab replacement key to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns, which means 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 the key switches. To do this, place a diode across each pin on the key switch and then solder it. This will protect the pins that are used for key switches from current and stop them from being shorted. A diode lets current only flow in only one direction. It is equipped with a visible indicator that is black, that shows the direction in which the current will flow.

Sanabria states that a number of the tools sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508, can help customers who are shopping or DIY customers to program replacement keys and restore immobilizer data. The tools plug into the OBD port and automatically guide the customer through the process, making it easier than replacing the computer in the vehicle.

Jump-starting the battery

Most people keep a set of jumper cables in their trunk for emergency situations however, jumping a battery for newer vehicles might not be the most efficient option. These cars are equipped with a variety of digital and computer systems that communicate with one another. A surge in voltage when a battery is connected to another one could cause damage to the parts making your car unusable.

Start the vehicle that is working and allow it to run for around two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface underneath the hood of your disabled car. The engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery, since it could ignite an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle you are not using and let it run for approximately five minutes before you disconnect them in reverse order. Be aware that the battery in the saab 93 key 9-3 will be charged during your drive, which means it will take a while for the battery to go back to normal. It is a good idea to purchase a spare key fob as soon as you can, since replacing the only functioning one requires the installation of a new computer module and a special program to convince it that the lost 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, they'll be charged. The reason is that it's costly to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It is recommended to have a backup key in the event of theft or other disaster the best solution is to purchase a second key as quickly as you can. Even if the key is "new", it won't work.

The dealer will charge you top dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a replacement key without having to replace the entire system. This could help you save a significant amount of money. It's also much less expensive than waiting until you lose your only key.
