saab 93 key fob replacement Key Programming

Saab cars built since 1994 use an immobilizer system that relies on coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The issue is that it can be very costly. Always keep a spare set of keys in your possession.

Transponder key

The transponder keys are keys with an electronic chip that transmits a signal to the car when it is inserted into ignition. The car then analyzes the signal to determine whether it matches the one on the key. If the signals match it will open itself and start. This is a great way to avoid car theft and keep your vehicle safe from thieves.

Transponder keys could be a popular addition to cars, but they are not as safe as traditional keys made of metal. The metal part of the traditional key is easily cut or copied, while a transponder has an electronic chip that safeguards it. The chip is equipped with an unique code that is programmed into the car's computers to identify it.

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

It is essential to ensure that you have an extra key for your saab 9 3 key replacement. This is especially important especially if you live in a rural location that has numerous car thieves. The good part is that you can find a new key for your Saab without having to go to an auto dealership and pay the high prices that they charge. In most instances, you can get a new key made on-the-spot at a fraction of the price of what you would pay at dealerships.

Wired key

Saab cars are typically delivered with two keys. If you have only one, it is recommended to purchase an additional key fob as soon as possible, because if you lose it, the car will require a new CIM unit and the locking cylinders will have to be replaced. This can be expensive especially for cars that are used.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most laborious part of the project and it will require lots of soldering. There isn't a standard method to go about it, but you should determine how to route and solder each column and row. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller wires and pins to connect.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins on the key switch from current and keep them from being shorted. A diode only allows the flow of current to be in one direction, and it comes with a an indicator in black that indicates the direction in which current will flow.

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

Jump-starting the battery

A lot of people keep a set in their trunks to jump start a car in an emergency, but this might not be a good option for vehicles with newer technology. They have numerous digital and electronic devices that communicate with one another. A voltage spike when a battery is hooked up to another could cause damage to these components, rendering your car unable to drive.

Start the vehicle you are using and allow it to run for approximately two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface under the hood of the affected vehicle. The engine block is a great option. The black cable is not to be connected to the negative terminal of the dead battery. This could create a spark, which would ignite gasoline in the engine compartment.

Once the cables are connected, you should start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. Be aware that the battery of the saab Ignition key 9-3 gets recharged when you drive, and it could take a while for the battery to go back to normal. It is recommended to purchase a second key fob, when you can. Replacing the one that works requires the installation and programming of a brand new computer chip.

Replacement Case

Saab owners usually only have one car key, and if that is lost, they'll be charged. The reason for this is that it's not cheap to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's best to have a backup key in the event of theft or other disaster, and the best way is to purchase an extra key as soon as you are able to. Even when the key is "new", it will not work.

Most locksmiths can't help you in the event that you only have one working key and the dealer will charge you high prices to replace the computer in your car to make a replacement. We can reset and reprogram the computer's EEEPROM in order to make it ready to accept a replacement key without replacing the entire system. This can save you a great deal of money. It's much cheaper than waiting until you lose the sole key.
