15 Incredible Stats About Saab Ignition Key Replacement
Saab Key Programming
Saab cars made since 1994 feature an immobilizer mechanism made up of coded keys. To add an additional key, you need an entirely new transponder and programming. This is usually done by the dealer using a special Tech2 diagnostic tool.
The issue is that it can be extremely expensive. Always keep a spare set of keys in your possession.
Transponder key
The transponder is a piece of key with an electronic chip. This chip sends a signal when the key is placed in the ignition. The car then checks to see if the signal matches the one on the key. If the signals are identical the car will be able to unlock itself and start. This is a great method to prevent auto theft and keep your vehicle secure from thieves.
Transponder keys are a popular feature in vehicles, but it is important to know that they are not as secure as traditional keys made of metal. 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 a unique code that is programmed into the car's computer in order 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 refuse to start.
It's important to make sure that you have a spare key for your Saab. This is particularly important if you live in a rural location where there are numerous car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their high cost. You can get a replacement key made on the spot for less than half what you would pay at a dealership.
Wired key
Saab cars typically come with two keys when new. If you have only one, it's an ideal idea to purchase an additional key fob as soon as is possible in case you lose it, your car will require an entirely new CIM unit and the locking cylinders have to be replaced. This can be expensive especially for used vehicles.
The next step is to connect the row and column wires to the microcontroller. This is the toughest part of the project, and it will require lots of soldering. It's not a standard way to go about it, but you need to consider how you will connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.
Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put an inverter over each pin on the key switch and then solder it. saab 9 3 key replacement will protect the pins that are used for key switches from current and keep them from being shorted. A diode allows current to only flow in only one direction. It has a visual indicator that is black, that indicates the direction in which current will flow.
Sanabria says that some of the tools available in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508 are able to assist shoppers or DIY customers to program replacement keys and restore immobilizer information. The tools connect to the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.
Jump-starting the battery
Most people keep an assortment of tools in their trunks to start a car in an emergency, however it might not be a good option for vehicles with newer technology. These cars are equipped with a variety of digital and computer systems that communicate with each other. A voltage surge when batteries are connected to another one could cause damage to the parts, rendering your car undriveable.
Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood--the engine block is a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline in the engine compartment.
Once the cables are connected, turn on the disabled vehicle and let it run for about five minutes before you disconnect them in reverse order. The battery in your Saab 9-3 is recharged while you drive. It will take a while for it to recharge again. You should purchase another key fob when you can. Replacing the only one that works requires the installation and programming of a new computer chip.
Replacement case
Many Saab owners have only one key for their car and if they lose that the cost will be. The reason is that it's not cheap to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. In the event of theft or other catastrophe it is recommended to have a spare key. Even if the key is "new" it won't work.
The dealer will charge you the most expensive dollar for only one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a new key without having to replace the entire system. This could help you save money. It's less expensive than waiting until you lose the only key.
