Saab Key Programming

Saab cars made since 1994 feature an immobilizer mechanism made up of coded keys. Adding an extra key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using a special Tech2 diagnostic tool.

The issue is that this can be quite costly. This is the reason why you should always keep a spare key in your possession.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal back to the car when it is inserted into ignition. The car will then check the signal to determine whether it is identical to that of the key. If the signals match the car will then unlock and begin. This is a great method to stop auto theft and keep your car secure from thieves.

Transponder keys are a popular feature in vehicles, but you should be aware they aren't as secure as classic metal keys. While the metal portion of a conventional key can be cut and copied but a transponder key is protected by an electronic chip. This chip contains a unique code programmed into the car's computer to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. In the absence of that, the car will reject the key and won't start.

It is vital to have an extra Saab key. This is especially important especially if you reside in a rural area where there are a lot of car burglars. The good part is that you can get a replacement key for your Saab 9-5 Key Replacement without needing to visit an auto dealer and pay the expensive prices that they demand. You can get a replacement key created on the spot for less than half what you would pay at dealerships.

Key for Wired

Saab cars usually come with two keys when they are new. If you have only one, it's an ideal idea to purchase an extra key fob as soon as you can, because if you lose it the car will require an entirely new CIM unit and the locking cylinders need to be replaced. This can be costly particularly if you are purchasing a used car.

The next step is connecting the wires of columns and row to your microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. It's not a standard way to do it, but you should determine how to connect and solder each column and row. For this keyboard, there are five rows and Saab 9-5 Key Replacement 17 columns, so there will be 22 microcontroller wires and pins to connect.

After the columns and rows are joined then it's time to connect the key switches. To do this, place a diode across each key switch pin and solder it. This will protect the pins of the key switch from current and keep them from being shorted. A diode can only allow the current to flow in a single direction, and it has an indicator of black color that indicates the direction in which current will flow.

Sanabria states that some of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508 will assist customers who are shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools connect to the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.

Jumpstarting the battery

A lot of people keep the set in their trunks to start a car in an emergency, but it might not be the best idea for newer cars. These vehicles are equipped with a number of electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another one could cause damage to the parts and render your vehicle unusable.

Start the working vehicle and allow it to run for around two minutes before connecting the cables to the one that is disabled. 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 beneath the damaged car's hood. The engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected, you can start the vehicle that has been disabled and saab 9-5 key replacement let it run for approximately five minutes before disconnecting them in reverse order. Keep in mind that the battery on the saab ignition key replacement 9-3 will be charged during your drive, which means it may take some time to get the battery down. You should consider purchasing an additional key fob as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Many Saab owners have only one key for their car and if they lose it, it's going to cost them. The reason is that it's not inexpensive to purchase a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. In the event of theft, or other catastrophe it is best to have an extra key. But don't buy a used key even it's "new." Claimed-new keys from aftermarket sellers will not work and are almost guaranteed to fail at the critical moment.

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 make a new replacement. We can reset and reprogram the computer's EEEPROM in order to get it ready to accept a new key without replacing the entire system. This can help you save money. It's also less expensive than waiting until you lose the only key.
