Saab Key Programming

saab 9-3 key programming cars made since 1994 come with an immobilizer system based on coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that this can be quite costly. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder key comes with an electronic chip that sends a signal to the car when it is inserted into ignition. The car will then check the signal to determine whether it is identical to the one that is in the key. If the signals are identical, the car will unlock itself and begin. This is a great method to deter auto theft and keep your car safe from thieves.

Transponder keys are an increasingly popular feature in automobiles, however you must be aware that they are not as secure as classic keys made of metal. While the metal parts of a conventional key can be cut and copied, a transponder is protected by an electronic chip. The chip has an individual code that is programmed into the car's computer to identify it.

The car will recognize the Saab keyfob and permit it to be turned 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 will not start in the event that the key has not been programmed to match.

It is essential to ensure that you have a spare key for your Saab. This is especially important especially if you reside in a rural location 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 a dealer and pay the hefty prices that they demand. In the majority of instances, you can get an original key made on the spot at a fraction of the cost you would pay at an auto dealer.

Key for Wired

Saab cars usually come with two keys upon purchase. If you only own one, you should purchase an additional key as fast as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.

The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and requires a significant amount of soldering. It's not a standard way to do it, but you need to consider how to open a saab 93 without a key you will route and solder each column and row. For this keyboard, there are five rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

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

Sanabria states that some of the tools available in auto parts stores, like the Autel MaxiIM IMM608PRO and IM508, can help customers shopping or DIY customers to program replacement saab car keys - Technetbloggers official website, keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks in case of emergency however, jumping a battery on newer automobiles might not be the most efficient option. These cars are equipped with a variety of computers and digital devices which communicate with each other. A voltage spike when batteries are connected to another can fry the components and render your vehicle unusable.

Start the vehicle you are using and let it run for about 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 say "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of your disabled vehicle. The engine block is a great choice. The black cable is not to be connected to the negative terminal of the dead battery. This could result in sparks, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, start the disabled vehicle and allow it to run for around five minutes before you disconnect them in reverse order. Remember that the battery on the saab 93 key programming 9-3 will be charged during your drive, which means it could take a while to get the battery back down again. It's a good idea invest in a spare key fob as soon as you can, because replacing the only working one requires the installation of a new computer module and a special program to convince it that the lost keys are not trying to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose that the cost will be. The reason is that it's not cheap to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. In the event of theft or other catastrophe it is recommended to have a spare key. Even if the key is "new", it won't work.

The dealer will charge you the highest dollar if you have only one working key. We can, however, reset and reprogram the computer's EEPROM to accept a new key without replacing the entire system. This could save you a significant amount of money. It's also less expensive than waiting until you lose your sole key.
