Saab Key Programming

Saab cars produced from 1994 have an immobilizer that relies on coded keys. Adding an extra key requires a new transponder and special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The issue is that this can be quite costly. It is recommended to always have a spare set of keys in your possession.

Transponder key

The transponder key is a piece of hardware with an electronic chip that sends a signal back to the car when it is inserted into ignition. The car checks to see whether the signal matches the one on the key. If the signals match the car will then open and start. This is a great method to protect your car from theft.

Transponder keys are a common feature in vehicles, but you should be aware that they aren't as secure as traditional metal keys. While the metal parts of a traditional key could be cut and copied but a transponder key is protected by an electronic chip. The chip is equipped with an unique code that is encoded into the car's system to identify it.

When a saab ignition key key fob is used the car recognizes it and allows it to turn on. The car can only recognize the key fob if it is equipped with an unmodified chip and programmed to match. The car won't start in the event that the key has not been programmed to match.

It's essential to ensure that you have an extra key for your saab car key. This is particularly true especially if you live in a rural region that has numerous car thieves. You can get a new key for your saab 9-3 key by going to the dealership without paying pricey cost. You can get the replacement key on the spot for less than half what you would pay at dealerships.

Key for Wired

Saab cars typically come with two keys upon purchase. If you only have one, you need to purchase an extra key as soon as you can. This is because if the key is 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 to wire the row and column wires to the microcontroller. This is the most tedious part of the project, and it will require a lot of soldering. It's not a standard way to do it, but you should plan how to connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

After the rows and column are soldered together, it is time to connect the key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and stop them from being shorted. A diode allows current to only flow in only one direction. It is equipped with a visible indicator with a black band that indicates which direction current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 will assist customers shopping or DIY customers to program replacement keys and restore data from the immobilizer. The tools plug into OBD ports and guide the customer through each step making the process simpler than replacing the car's computer.

Jump starting the battery

A lot of people keep a set of jumper cables in their trunks in case of emergency however, jumping a battery in newer vehicles may not be the best option. These vehicles are equipped with a number of digital and electronic devices that communicate with each other. A surge in voltage while the battery is connected to another can fry these components and render your car unable to drive.

Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface underneath the car's hood. The engine block would be a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which could ignite the gasoline inside the engine compartment.

Once the cables are connected, start the disabled vehicle and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery in your saab car keys 9-3 is charged while you drive, so it may take some time to get the battery back to its original level. It's a good idea purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a brand new computer module and special programming to convince it that your lost keys are not trying to steal the car.

replacement saab key Case

Saab owners often only have one car key, and if it is lost, they'll be charged. The reason for this is that it's expensive to replace a key, and this 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 best to have an extra key. Even even if the key is "new", it will not function.

Most locksmiths aren't able to help in the event that you only have one working key, and the dealer will charge you top dollar to replace the computer in your car to create a replacement. However, we can reset and re-program the computer's EEPROM to prepare it to accept the new key, without replacing the entire system. This could save you a lot of money. It's also a lot cheaper than waiting until you lose your only key.
