Saab Key Programming

Saab cars made since 1994 come with an immobilizer system built on coded keys. A new transponder is required to allow the addition of an additional key, as well as special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

It can be costly. This is why you should always have a spare key at hand.

Transponder key

The transponder keys are keys with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car then checks to see if the signal matches the one on the key. If the signals match it will open itself and start. This is an excellent way to safeguard your car from theft.

Transponder keys are an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and Saab Key Programming copied however, a transponder is secured by an electronic chip. This chip contains an unique code that is programmed into the car's computers 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 programmed to match. If not, the car will refuse to accept the key and will not start.

It's crucial to ensure that you have an extra key for your Saab. This is especially important when you live in a rural location where there are numerous car thieves. You can get a new key for your Saab by going to the dealership and not paying their pricey costs. In the majority of cases, you can have a new key made on-the-spot at a fraction of the price of what you would pay at the dealer.

Wired key

saab 93 key cars typically come with two keys when they are new. If you only have one, it is best to acquire an extra key fob as soon as possible, because if you lose it, the car will require a new CIM unit, and the locking cylinders have to be replaced. This can be costly particularly for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a standard way to go about it, but you should plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are soldered, it's the time to connect them to the key switches. To do this you must place a diode over each pin on the key switch and then solder it. This will shield the key switch pins from current and also prevent them from being shorted. A diode allows current to only flow in one direction. It is equipped with a visible indicator, a black band, that indicates which direction current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- could assist customers at the shop or DIY customers in certain cases programme replacement keys and recover lost immobilizer information, Sanabria says. The tools connect to the OBD port and automatically guide the customer through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have an item in their trunk to jump-start their car in an emergency, but this might not be a good idea for cars with more modern technology. These vehicles are equipped with a number of computers and digital devices that communicate with each other. A surge in voltage when the battery is connected to another can fry these components, rendering your car unable to drive.

Start the working vehicle and let it run for about two minutes before you connect 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 clean unpainted metal surface under the hood of the affected car. The engine block is a great alternative. Don't connect the black cable to the negative terminal of the dead battery as this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. Be aware that the battery of the saab 93 key 9-3 will be charged when you drive, and it could take a while for the battery to come down. It's a good idea buy a spare key fob as soon as you can, since replacing the one that works requires the installation of a brand new computer module and a special program to convince it that your lost keys are not trying to steal the car.

Replacement Case

Saab owners often only have one car key, and if it is lost, they will be charged. It's expensive to buy an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft, or any other disaster, it is best to have an extra key. However, don't purchase a secondhand key even when it's "new." Keys that are claimed-new purchased from third-party sellers won't perform and are almost certain to fail at the critical moment.

The dealer will charge you the most expensive dollar if you have only one working key. We can reset and reprogram the EEEPROM of your computer to be able to accept a new key without having to replace the entire system. This can help you save a significant amount of money. It's less expensive instead of waiting until you lose the only key.
