Saab Key Programming

saab key battery key programmer (recent post by Opensourcebridge) cars built from 1994 have an immobilizer system that relies on coded keys. A new transponder is required to allow the addition of an extra key, as well as special programming. This is usually handled 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 on hand.

Transponder key

The transponder keys are keys equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then examines the signal to determine if it matches the one on the key. If the signals match the car will then open and start. This is a great method to protect your car from theft.

Transponder keys are a favored feature in cars, but it is important to know that they aren't as secure as traditional metal keys. While the metal parts of a traditional key can be cut and copied, a transponder is protected by an electronic chip. The chip has a unique code that's programmed into the car's computer in order to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. However, it can only do so if the key fob has an unmodified chip that has been programmed to match. Otherwise, the car would refuse to accept the key and will not start.

It is important to have an extra Saab key. This is particularly true for those who live in a rural area with many car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their high prices. In the majority of cases, you can have an original key made on the spot at a fraction of the cost you'd pay at an auto dealer.

Wired key

Saab cars are usually provided with two keys. If you only have one, you should get an additional key as soon as you can. This is because, if it's lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive particularly for used cars.

The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a good amount of soldering. It's not a common way to do it, but you should think about how to route and solder each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins to connect.

Once the rows and columns are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will protect the pins on 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 an indicator of black color that indicates 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 assist customers at the shop or DIY customers in certain cases replace keys in the program and restore lost immobilizer data, Sanabria says. The tools connect to the OBD port and automatically guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk in case of emergency however, jumping a battery on modern cars might not be the most efficient option. These vehicles are equipped with a number of digital and computer systems that communicate with each other. A voltage surge when a battery is connected to another can fry the components making your car unusable.

Start the working vehicle 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 have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface under the hood of the affected vehicle. The engine block is an excellent option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks that could ignite the gasoline in the engine compartment.

Once the cables are connected, you can begin the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. The battery in your saab 93 key 9-3 is recharged while you drive. It takes a while for it to recharge again. You should invest in an additional 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

Many saab 93 key replacement owners only have one key for their car and if they lose it, they'll be charged. The reason is that it's not cheap to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft, or any other calamity it is recommended to have an extra key. Even if the key is "new", it won't work.

The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without replacing the entire system. This can save you a significant amount of money. It's less expensive rather than wait until you lose the sole key.
