5 Killer Quora Answers On Saab Ignition Key Replacement
Saab Key Programming
Saab Ignition Key cars built from 1994 have an immobilizer system that is based on coded keys. The addition of a key requires a new transponder and special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.
This can be expensive. This is the reason why you should always have a spare key at hand.
Transponder key
The transponder is a key equipped with an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car then examines the signal to determine whether it is the same as the one that is in the key. If the signals are identical the car will then unlock itself and start. This is a great method to safeguard your car from theft.
Transponder keys can be an extremely popular accessory for cars, but they're not as secure as traditional metal keys. The metal component of a traditional key can be easily cut or copied, while transponders are protected by an electronic chip that safeguards it. This chip contains an unique code which is programmed into a car's computers in order to identify it.
The car will recognize the Saab keyfob, and allow it to turn on. However, it will only do so if the key fob has a non-modified chip that has been programmed to match. The car won't start in the event that the key has not been programmed to match.
It is essential to have an extra saab keys key. This is particularly important especially if you reside in a rural region where there are a lot of car burglars. The good news is that it's possible to get a replacement key for your Saab without having to go to an auto dealership and pay the hefty prices that they ask. You can get an original key made on the spot at a fraction of the price you'd pay at a dealership.
Wired key
Saab cars usually come with two keys when new. If you only own one, you should get an additional key as fast as you can. This is because, if it's lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be expensive, especially for used cars.
The next step is to wire the wires for the column and row to the microcontroller. This is the most difficult part of the project, and it will require a lot of soldering. There is no standard method to accomplish this, however it's important to plan out how you will route and solder the rows and columns. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.
After the columns and rows are soldered together after which it is time to connect the key switches. To do this, place a diode on each key switch pin and solder it. This will protect the pins from current, and prevent them from being cut off. A diode allows the current to flow in a single direction, and it has a black band visual indicator that indicates the direction in which current will flow.
Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- can aid shop customers or DIY customers in certain cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into the OBD port and automatically guide the user through the procedure, making it simpler than replacing the computer inside the vehicle.
Jump-starting the battery
The majority of people have a set of jumper cables in their trunk in case of emergency, but jumping a battery on modern vehicles might not be the best choice. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A surge in voltage when the battery is connected to another could cause damage to the components and render your vehicle unusable.
Connect the cables to the vehicle that is operating. 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 to a clean, unpainted metal surface underneath the hood of the disabled vehicle. 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, which could ignite the gasoline that is in the engine compartment.
Once the cables are connected the vehicle you are not using and allow it to run for around five minutes before you disconnect them in reverse order. Remember that the battery on your Saab 9-3 is recharged when you drive, and it could take a while to get the battery back to normal. It's a good idea purchase a spare fob as soon as you can, since replacing the only functioning one requires the installation of a brand new computer module and a special program to convince it that your missing keys aren't trying to steal the car.
replacement saab key Case
Saab owners often only have one car key, and if that is lost, they will be charged. It's expensive to buy the key and also requires replacing the CIM or TWICE in the case of older models. In the event of theft or any other catastrophe, it is best to have an extra key. Even if the key is "new" it will not function.
The dealer will charge you the highest dollar if you have only one working key. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept the new key, without replacing the whole system. This could save you a great deal of money. It's also less expensive than waiting until you lose your sole key.
