Three Reasons Why Three Reasons Your Saab Ignition Key Replacement Is Broken (And How To Fix It)
Saab Key Programming
Saab cars manufactured since 1994 utilize an immobilizer system that is based 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.
The issue is that it can be extremely expensive. It is recommended to always have a spare set of keys in your possession.
Transponder key
The transponder key is a key equipped with an electronic chip. It sends a signal to car when it is inserted into the ignition. saab 9-3 replacement key to see whether the signal matches the one on the key. If the signals are identical, the car will unlock itself and begin. This is a fantastic way to guard your car against theft.
Transponder keys are an increasingly popular feature in automobiles, but you should be aware they aren't as secure as classic keys made of metal. While the metal component of a traditional key can be cut and copied however, a transponder is secured by an electronic chip. The chip has an individual 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. The car can only recognize the key fob if it is equipped with an unmodified chip and has been programmed to match. The car will not start when the key isn't programmed to match.
It is crucial to have a spare Saab key. This is especially true if you reside in a rural area with many car thieves. You can purchase a new key for your Saab by going to the dealership without paying high cost. You can get a replacement key created on the spot for less than half the cost you would pay at an auto dealer.
Key for Wired
Saab cars are usually delivered with two keys. If you have only one, you should purchase an additional key as fast as you can. This is because, if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This can be costly, especially for used cars.
The next step is to connect the row and column wires to the microcontroller. This is the most laborious component of the project and it will require lots of soldering. There is no standardized way to accomplish this, however it is important to think about the routes you'll use to 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 to connect.
After the columns and rows are soldered together It is now time to connect the key switches. To do this, place a diode across each key switch pin and solder it. This will shield the pins that are used for key switches from current and prevent them from being shorted. A diode allows the flow of current to be in one direction, and has a an indicator of black color that indicates the direction in which current will flow.
A few of the tools that are available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can assist customers at the shop or DIY users in some cases replace keys in the program and restore lost immobilizer information, 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
Most people keep a few sets of jumper cables in their trunks to use in an emergency, but jumping a battery on newer cars might not be the most efficient option. These cars have a variety of computers and digital devices that communicate with one another. A surge of voltage when the battery is connected another can fry the components making your car inoperable.
Connect the cables to the vehicle working. Allow it to run for two minutes. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface beneath the hood of the disabled car. The engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could result in sparks, which could ignite the gasoline inside the engine compartment.
Once the cables are connected, you need to start the car and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged as you drive. It will take some time for it to drop back down. You should consider purchasing an additional key fob when you can. Replacing the original one that works requires the installation and programming of a brand new computer chip.
Replacement Case
Saab owners usually only have one car key, and if that is lost, they will be charged. The reason is that it's not cheap to add a new key, and that involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's recommended to have a backup key in case of theft or other disaster, and the best way is to purchase a second key as early as you can. Even it's "new", it will not work.
The dealer will charge you the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM in order for it to accept a replacement key without replacing the entire system. This can save you a lot of money. It's also less expensive than waiting until you lose the only key.
