Saab Key Programming

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

The problem is that this could be quite costly. It is always advisable to keep a spare set of keys available.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is put into the ignition. The car then analyzes the signal to determine whether it is identical to that of the key. If the signals are in sync the car will then open and start. This is a great method to avoid auto theft and keep your car secure from thieves.

Transponder keys are an increasingly popular feature in vehicles, but you must be aware that they are not as secure as classic keys made of metal. While the metal portion of a traditional key can be cut and copied, a transponder is protected by an electronic chip. The chip is a unique code that's programmed into a car's computers in order 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 a chip that is unmodified and programmed to match. The car won't start when the key isn't programmed to match.

It is important to have a spare Saab key. This is especially true when you live in a rural area, where there are many car thieves. You can get a brand new key for your Saab by visiting the dealership without paying their pricey costs. You can get the replacement key on the spot at a fraction of the cost you would spend at a dealership.

Key for Wired

saab keys replacement cars usually come with two keys when new. If you only have one, it's recommended to purchase an extra key fob as soon as is possible since if you lose it, your car will require a new 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 difficult part of the project and will require a great deal of soldering. It's not a common way to do it, but you need to consider how you will connect and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to the key switches. To do this, you need to place an inverter over each key switch pin and then solder it. This will protect the pins on the key switch from current and also prevent them from being shorted. A diode can only allow current to flow in one direction, and it has an indicator in black that indicates which way the current will flow.

Some of the tools offered at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- could aid shop customers or DIY users in some cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it more simple than replacing the computer inside the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery on modern automobiles might not be the best option. These vehicles have many electronic devices and computers that communicate with one another. A voltage surge while a battery is hooked up to another battery could fry the components and render your car unable to drive.

Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood--the engine block is an ideal choice. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, saab Key programming which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, Saab key Programming you can start the vehicle you are not using and let it run for about five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 will be recharged while you drive. It will take a while for it to drop back down. It's a good idea buy a spare key fob as soon as you can, because replacing the sole working one requires the installation of a brand new computer module and a special program to convince the system that your lost keys aren't in the process of trying to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose that key, it will cost them. The reason is that it's not cheap to buy a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft or other catastrophe it is recommended to have a spare key. However, don't purchase a secondhand key even it's "new." Keys that are claimed to be new from aftermarket sellers will not be effective and are almost guaranteed to fail in 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 for it to accept a replacement key without the need to replace the entire system. This could help you save a significant amount of money. It's also less expensive than waiting until you lose your one key.
