saab ignition key Key Programming
Saab cars that were built prior to 1994 have an immobilizer system that is based on codes for keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.
The issue is that this could be quite costly. You should always keep 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 placed in the ignition. The car will then check the signal to determine whether it is identical to the one in the key. If both signals match, the car will unlock itself and begin. This is a great way to guard your car against theft.
Transponder keys are a favored feature in cars, but you should be aware they aren't as secure as classic keys made of metal. While the metal part of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip is equipped with a unique code that is embedded 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. However, it can only do this if your key fob is unmodified and has a chip that has been programmed to match the original. Otherwise, the car will reject the key and won't start.
It's crucial to ensure that you have an extra key for your Saab. This is especially true when you live in a rural location where there are a lot of car thieves. You can get a new key for your Saab by visiting the dealership, without having to pay their high cost. In the majority of cases, you can have a new key made on-the-spot for less than half the price of what you would pay at an auto dealer.
Key for Wired
saab car keys cars are usually supplied with two keys. If you only own one, you need to purchase an extra key as soon as you can. This is because if you lose it and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.
The next step is to wire the wires for the column and row to the microcontroller. This is the most tedious aspect of the project and it will require a lot of soldering. There isn't a standard method to go about it, but you need to determine how to get a saab replacement key to route and solder each column and row. For this keyboard, there are five rows and 17 columns. So there will be 22 microcontroller wires and pins to connect.
Once the rows and columns are soldered, it's the time to connect them to the key switches. To do this, put a diode across each pin on the key switch and then solder it. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode only allows the current to flow in a single direction, and it comes with a the black band as a visual indicator that shows the direction in which current will flow.
A few of the tools that are available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY users in some cases replace keys in the program and restore lost immobilizer information, Sanabria says. The tools plug into the OBD port and automatically guide the user through the process, making it easier than replacing the computer in the vehicle.
Jump starting the battery
Most people keep the set in their trunk to start a vehicle in an emergency, but it may not be the best idea for vehicles that are newer. These vehicles are equipped with a number of digital and computer systems that communicate with one another. A surge of voltage when the battery is connected to another could cause damage to the components, rendering your car undriveable.
Connect the cables to the vehicle operating. Allow it to run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood. The engine block is an ideal choice. Do not connect the black cable to the negative terminal of the dead battery as it could spark an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, turn on the vehicle that has been disabled and let it run for approximately five minutes before disconnecting the cables in reverse order. The battery in the Saab 9-3 will charge as you drive. It will take some time for it to drop back down. It is recommended to purchase an additional 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 key replacement cost owners only have one key for their vehicle and if they lose that it's going to cost them. The reason is that it's costly to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is recommended to have a backup key in the event of theft or any other catastrophe and the best option is to purchase an additional key as quickly as you can. But don't buy a used key, even it's "new." Keys that are claimed to be new from aftermarket sellers will not perform and are almost certain to fail in the most critical moment.
The dealer will charge you the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to make it ready to accept a replacement key without replacing the entire system. This can help you save a significant amount of money. It's also much less expensive than waiting until you lose the only key.
