saab key fob replacement Key Programming

Saab ignition key replacement cars made since 1994 utilize an immobilizer system that relies on key codes. The addition of a key requires an entirely new transponder and programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

It can be costly. It is recommended to always have a spare set of keys available.

Transponder key

The transponder can be described as a key with an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car then analyzes the signal to determine if it matches the one on the key. If the signals match then the car will be able to unlock and start. This is a great way to prevent auto theft and keep your vehicle secure from thieves.

Transponder keys are a favored feature in vehicles, but it is important to know that they aren't as secure as classic metal keys. The metal component of the traditional key can easily be cut and copied, however transponders are protected by an electronic chip that safeguards it. The chip is a unique code that is programmed into a car's computer order to identify it.

The car will recognize the Saab keyfob, and allow it to be turned on. The car will only recognize the key fob if it is equipped with a chip that is unmodified and has been programmed to match. In the absence of that, the car will refuse to accept the key and will not start.

It's essential to ensure that you have a spare key for your saab 9 3 key replacement. This is particularly true when you live in a rural region that has many car thieves. You can get a brand new key for your Saab by going to the dealership and not paying their high costs. In most instances, you can get a new key made on-the-spot for less than half the cost you'd pay at a dealer.

Wired key

Saab cars are usually supplied with two keys. If you have only one, it's a good idea to get an extra key fob as soon as possible in case you lose it, the car will require a new CIM unit, and the locking cylinders will have to be replaced. This can be costly especially for used vehicles.

The next step is to connect the wires of the column and row to the microcontroller. This is the most difficult part of the project and will require a great amount of soldering. There isn't a standard method to do it, but you need to 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 now time to connect the key switches. Solder a diode on each key switch pin. This will protect the pins that are used for key switches from current and also prevent them from being shorted. A diode permits current to only flow in one direction. It has a visual indicator that is black, that indicates the direction in which current will flow.

Sanabria says that a few of the tools offered in auto parts stores, like the Autel MaxiIM IM608PRO and the IM508, can help shoppers or DIY users to program replacement keys and restore data from the immobilizer. The tools connect to OBD ports and guide the customer through each step and make the process more straightforward than replacing the vehicle's computer.

Jump starting the battery

The majority of people have a set of jumper cables in their trunk for emergency situations, but jumping a battery on newer cars might not be the best choice. These vehicles are equipped with digital and computer systems that communicate with one another. A voltage spike when a battery is connected to another one could cause damage to the parts and render your vehicle 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 say "POS" or "+".) Attach the other end to a clean unpainted metal surface underneath the hood of the disabled vehicle. The engine block is a good alternative. Do not connect the black cable to the negative terminal on the dead battery as this could cause a spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the car and let it run for about five minutes. Then, disconnect them in reverse. Be aware that the battery in the Saab 9-3 gets recharged while you drive, so it may take some time for the battery to go back to its original level. It is a good idea to purchase a spare key fob as soon as you can, because replacing the only working one requires the installation of a new computer module and a special program to convince it that your lost keys aren't in the process of trying to steal the car.

replacement saab key case

Saab owners often only have one car key, and if that is lost, they'll be charged. The reason for this is that it's not inexpensive to replace a key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. In the event of theft or any other disaster it is recommended to have an extra key. Don't purchase a used key, even if it's "new." Claimed-new keys from aftermarket sellers will not be effective and are almost guaranteed to fail at the crucial moment.

Most locksmiths aren't able to help with a single working key and the dealer will charge you for the cost of replacing the computer in your vehicle to make a replacement. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without replacing the entire system. That can save you a lot of money. It's also a lot cheaper than waiting until you lose your one key.
