Saab Key Programming

Saab cars built since 1994 utilize an immobilizer that relies on a set of keys. A new transponder is required in order to enable the inclusion of an additional key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. Always keep an extra set of keys on hand.

Transponder key

The transponder can be described as a key with an electronic chip. This chip sends a signal when the key is inserted in the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals are in sync then the car will be able to unlock and start. This is a fantastic way to protect your vehicle from theft.

Transponder keys can be a popular addition to automobiles, but they are not as safe as traditional metal keys. While the metal parts of a traditional key could be cut and saab 93 replacement Key copied, a transponder is protected by an electronic chip. The chip is equipped with a unique code embedded into the car's computer to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car will only recognize the key fob if the device has a chip that is unmodified and programmed to match. Otherwise, the car will reject the key and won't start.

It's important to make sure that you have a spare key for your saab 93 replacement key. This is particularly important for those who live in a rural area, where there are many car thieves. You can get a brand new key for your Saab by going to the dealership without paying high prices. In the majority of cases, you can have a new key made on-the-spot for less than half the price of what you'd pay at the dealer.

Key for Wired

Saab cars are usually delivered with two keys. If you have only one, it is recommended to get an extra key as soon as you can. This is because if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be expensive especially for used vehicles.

The next step is connecting the row and columns wires to your microcontroller. This is the toughest part of the project and will require a lot of soldering. There is no standardized way to accomplish this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and saab 93 replacement key pins to connect.

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

Sanabria says that a few of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and help the customer through each step, making the process easier than replacing the vehicle's computer.

Jump starting the battery

A lot of people keep the set in their trunk to start a car in case of emergency, however it might not be the best option for vehicles with newer technology. They have numerous digital and computer systems that communicate with one another. A surge in voltage when the battery is connected another one could cause damage to the parts, rendering your car undriveable.

Start the vehicle you are using and let it run for about two minutes before connecting the cables to the disabled one. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled vehicle's hood. An engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could cause a spark, which would ignite gasoline in the engine compartment.

After the cables have been connected, start the car and let it run about five minutes. Then disconnect them in reverse. Remember that the battery on your Saab 9-3 is charged when you drive, so it can take a while for the battery to come down. It's a good idea to invest in 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 it that your missing keys aren't in the process of trying to steal the car.

Replacement Case

Saab owners typically only have one car key, and if it is lost, they'll be charged. The reason is that it's costly to purchase a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It is best to have a spare key in the event of theft or other disaster and the best option is to purchase a second key as soon as you can. Even even if the key is "new", it won't work.

Most locksmiths can't help you when you only have one working key and the dealer will charge you for the cost of replacing the computer in your vehicle to create a replacement saab car keys. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a new key without having to replace the entire system. That can save you a lot of money. It's much cheaper rather than wait until you lose the only key.
