The 12 Best Saab Ignition Key Replacement Accounts To Follow On Twitter
Saab Key Programming
Saab cars built since about 1994 come with an immobilizer system made up of 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.
It can be costly. It is recommended to always have an extra set of keys in your possession.
Transponder key
The transponder key is a key equipped with an electronic chip. It transmits a signal to the car when it is inserted into ignition. The car is able to check whether the signal matches the one on the key. If the signals are in sync it will unlock and start. This is a great way to avoid car theft and keep your car safe from thieves.
Transponder keys can be a popular addition to automobiles, but they are not as secure as traditional keys made of metal. While the metal part of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. The chip has a unique code that is programmed into a car's computer in order to identify it.
The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob if the device has a chip that is unmodified and has been programmed to match. In the absence of that, the car will reject the key and not start.
It is essential to ensure that you have a spare key for your Saab. This is especially important especially if you reside in a rural area, where there are a lot of car thieves. The good news is that it's possible to find a replacement key to your Saab without needing to visit an auto dealer and pay the hefty prices they ask. You can have an original key made on the spot for less than half what you would pay at a dealership.
Wired key
Saab cars usually come with two keys when they are new. If you only own one, it is recommended to get an additional key as soon as you can. This is because if you lose it the car will require a new CIM and the locking cylinders replaced. This could be expensive especially if you're buying a used car.
The next step is to connect the wires for columns and row to your microcontroller. This is the most challenging part of the project and will require a large amount of soldering. There is no standardized way to accomplish this, however it is important to think about the way you'll route and solder the rows and columns. There are G28 Car Keys and pins to connect for this keyboard. It has five rows and 17 column.
Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will shield the pins on the key switch from current and also prevent them from being shorted. A diode lets current only flow in only one direction. It is equipped with a visible indicator with a black band that shows the direction in which the current will flow.
Some of the tools available at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- may help shop customers or even DIY customers in some cases create replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.
Jump starting the battery
A majority of people keep an assortment of tools in their trunk to jump-start their vehicle in the event of an emergency, but this might not be a good idea for cars with more modern technology. These vehicles are equipped with numerous electronic devices and computers that communicate with one another. A surge in voltage while the battery is connected to another can fry these components, rendering your vehicle unable to drive.
Start the vehicle you are using and let it run for about two minutes before you connect the cables to the one that is disabled. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface underneath the vehicle's hood. An engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery as it could spark an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, start the vehicle that has been disabled and let it run for approximately five minutes before disconnecting them in reverse order. The battery in the Saab 9-3 will charge while you drive. It takes a while for it to fall back. It's a good idea purchase a spare fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and a special program to convince it that the lost keys aren't attempting to steal the car.
Replacement case
Many Saab owners only have one key for their vehicle and if they lose it, it's going to cost them. It's costly to add the key and also requires replacing the CIM or TWICE in the case of older models. It's recommended to have a backup key in case of theft or other disaster the best solution is to purchase a second key as soon as you are able to. Don't purchase a used key, even the case that it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't work and are almost guaranteed to fail in the crucial moment.
Most locksmiths can't help you when you only have one working key, and the dealer will charge you high prices to replace the computer in your vehicle to create a replacement. We can, however, reset and reprogram the computer's EEPROM to accept an alternative key without replacing the entire system. This can help you save a significant amount of money. It's much cheaper instead of waiting until you lose the sole key.
