saab centre milton keynes Key Programming

Saab cars manufactured since 1994 utilize an immobilizer system that relies on key codes. In order to add a second key, it requires an entirely new transponder and programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that this could be very costly. Always keep an extra set of keys available.

Transponder key

The transponder is a piece of key equipped with an electronic chip. The chip transmits a signal when the key is put in the ignition. The car will then check the signal to see whether it is identical to that of the key. If both signals match it will open itself and begin. This is an excellent way to safeguard your car from theft.

Transponder keys can be an extremely popular accessory for automobiles, but they are not as secure as traditional keys made of metal. The metal portion of a traditional keys can be easily cut or copied, while transponders are protected by an electronic chip that guards it. This chip contains a unique code encoded into the car's system to identify it.

The car will recognize the Saab keyfob and allow it to turn on. However, it will only do so if the key fob has an unmodified chip that has been programmed to match it. The car will not start in the event that the key is not programmed to match.

It's essential to ensure that you have a spare key for your saab 9-3 key fob programming. This is especially important for those who live in a rural area with numerous car thieves. The good news is that it's possible to get a replacement key for your saab key fob without having to go to a dealer and pay the high prices that they charge. In most cases, you can have a new key made on-the-spot for less than half the cost of what you'd pay at dealerships.

Wired key

Saab cars are usually provided with two keys. If you have only one, it's an ideal idea to purchase an additional key fob as soon as is possible, because if you lose it, your car will require an entirely new CIM unit, and the locking cylinders have to be replaced. This can be costly especially if buying a second-hand car.

The next step is to wire the row and column wires to the microcontroller. This is the most difficult component of the project and will require a lot of soldering. It's not a common way to do it, but you need to determine how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller wires and pins that you need to connect.

After the columns and rows are joined then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode can only allow the flow of current to be 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, such as the Autel MaxiIM IM608PRO and IM508, can help shoppers or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and guide the customer through the procedure, making it simpler than replacing the computer inside the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunks to use in an emergency, but jumping a battery on modern automobiles might not be the best choice. These vehicles are equipped with digital and computers that communicate with each other. A surge in voltage when a battery is connected to another could cause damage to the components making your car unusable.

Connect the cables to the vehicle that is operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface underneath the hood of the affected vehicle. The engine block is a good choice. Don't connect the black cable to the negative terminal of the dead battery, since it could ignite a spark that ignites the gasoline in the engine bay.

After the cables have been connected, you should start the car and allow it to run for around five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will recharge while you drive. It may take a while it to fall back. It is a good idea to buy a spare key fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't attempting to steal the car.

Replacement case

Saab spare Key owners usually have only one car key, and if it is lost, they will be charged. It's expensive to purchase keys and will require replacing the CIM or TWICE in the case of older models. It's recommended to have a backup key in case of theft or other disaster and the most effective way is to purchase an extra key as early as you can. But don't buy a used key, even if it's "new." Keys that are claimed-new from aftermarket sellers will not work and are likely to fail in the crucial moment.

The dealer will charge you the most expensive dollars if you only have one working key. However, we can reset and re-program your computer's EEPROM to accept the new key, without replacing the entire system. That can help you save money. It's also less expensive than waiting until you lose your one key.
