Saab Key Programming

Saab cars that were built prior to 1994 have an immobilizer system made up of coded keys. The addition of a key requires a new transponder and special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that this could be quite costly. You should always keep an extra set of keys at hand.

Transponder key

The transponder is a type of key that has an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car then examines the signal to determine whether it matches that of the key. If the signals match, the car will unlock and begin. This is a great way to prevent car theft and keep your vehicle safe from thieves.

Transponder keys are a favored feature in vehicles, but you must be aware that they aren't as secure as traditional metal keys. The metal component of the traditional key can easily be copied and cut, but a transponder has an electronic chip that safeguards it. The chip is equipped with a unique code encoded into the car's system to identify it.

When a saab replacement key programming key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start in the event that the key is not programmed to match.

It's crucial to ensure that you have a spare key for your Saab. This is particularly important if you live in a rural area where there are many car thieves. The good part is that you can find a new key for your saab 9-3 key not accepted contact service without having to go to an auto dealer and pay the expensive prices that they demand. You can get a replacement key created on the spot at a fraction of what you would spend at the dealership.

Wired key

Saab cars usually come with two keys when they are new. If you only have one, you should purchase an additional key as soon as you can. This is because, if it's lost and the car needs a new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the toughest part of the project and will require lots of soldering. It's not a standard way to do it, but you need to think about how to Program saab 9-3 key fob to connect and solder each column and row. There are 22 microcontroller wires as well as pins to connect to this keyboard. It has 5 rows and 17 columns.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode on each key switch pin. This will shield the key switch pins from current and keep them from being shorted. A diode can only allow the current to flow in a single direction, and it comes with a a black band visual indicator that shows 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 -- could assist customers at the shop or DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools plug into the OBD port and guide the user through the procedure, making it simpler than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunks in case of emergency, but jumping a battery on modern cars might not be the best choice. They have numerous electronic devices and computers that communicate with one another. A voltage surge while a battery is hooked up to another could cause damage to these components and leave your car unable to drive.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled car's hood. The engine block would be a good choice. 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 that is in the engine compartment.

Once the cables are connected, you can start the vehicle and let it run about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 is recharged as you drive. It takes a while for it to fall back. It is a good idea to purchase a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and a special program to convince the system that your lost keys aren't attempting to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose it, they'll be charged. The reason for this 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 any other catastrophe it is recommended to have an extra key. Don't buy a secondhand key even the case that it's "new." Keys that are claimed-new from aftermarket sellers will not work and are likely to fail at the critical moment.

The dealer will charge you top 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 could save you a significant amount of money. It's also less expensive than waiting until you lose your only key.
