saab ignition key Key Programming

Saab cars built since 1994 use an immobilizer system that is based on key codes. A new transponder is required for addition of an additional key, and 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 have a spare key available.

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 inserted into the ignition. The car checks to see if the signal matches the one on the key. If the signals match the car will then unlock and start. This is a fantastic way to protect your car from theft.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as safe as traditional metal keys. While the metal part of a conventional key can be cut and copied however, a transponder is secured by an electronic chip. The chip has 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 will only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car won't start when the key isn't programmed to match.

It's crucial to ensure that you have an extra key for your saab keys replacement. This is especially true especially if you live in a rural location that has numerous car thieves. You can purchase a new key for your Saab by going to the dealership without paying high cost. You can get an original key made on the spot for less than half the price you'd pay at dealerships.

Key for Wired

Saab Ignition Key Replacement cars typically come with two keys when new. If you have only one, you should purchase an additional key as quickly as you can. This is because, if it's lost the car will require a new CIM and the locking cylinders replaced. This can be costly especially if purchasing a used vehicle.

The next step is to connect the row and columns wires to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. It's not a standard way to do it, but you must consider how to open a saab 93 without a key you will connect and solder each column and row. There are 22 microcontroller pins and wires to connect for this keyboard. It has 5 rows and 17 column.

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 that are used for key switches from current and prevent them from being shorted. A diode allows current to flow in one direction, and it comes with a a black band visual indicator that indicates the direction current will flow.

Sanabria states that a number of the tools offered in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508 can assist customers shopping or DIY customers to program replacement keys and restore immobilizer data. The tools connect to 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

The majority of people have a set of jumper cables in their trunks to use in an emergency however, jumping a battery on newer cars might not be the best idea. These vehicles are equipped with computers and digital devices which communicate with each other. A voltage spike when the battery is connected to another battery could damage the components, rendering your car undriveable.

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 clear, unpainted metal surface beneath the hood of the damaged vehicle. The engine block is an excellent alternative. The black cable should not be connected to the negative terminal of the dead battery. This could cause sparks that could ignite the gasoline in the engine compartment.

After the cables have been connected, start the vehicle and allow it to run for around five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will be recharged while you drive. It takes a while for it to drop back down. You should invest in an additional key fob when you can. Replacing the only one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Many Saab owners only have one key for their car and if they lose that the cost will be. It's expensive to purchase keys and will require replacing the CIM or TWICE for older models. In the event of theft or other catastrophe it is recommended to have a spare key. Even when the key is "new" it will not function.

The dealer will charge you top dollar for only one working key. We can, however, reset and re-program the computer's EEPROM to prepare it to accept the new key without having to replace the whole system. This could save you a lot of money. It's much cheaper rather than wait until you lose your only key.
