Buzzwords De-Buzzed: 10 Different Ways To Say Saab Ignition Key Replacement
Saab Key Programming
Saab cars built since about 1994 have an immobilizer system made up of coded keys. The addition of a key requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.
The issue is that this could be very expensive. This is why it is important to always have a spare key on hand.
Transponder key
The transponder keys are keys with an electronic chip that sends a signal to car when it is put into the ignition. The car then examines the signal to see whether it is identical to the one on the key. If the signals match the car will then unlock itself and start. This is a great method to guard your car against theft.
Transponder keys are a favored feature in cars, but you must be aware that they aren't as secure as classic keys made of metal. The metal part of the traditional key is easily copied and cut, but transponders have an electronic chip which protects it. This chip contains a unique code that is programmed 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 the device has an unmodified chip and programmed to match. The car won't start in the event that the key has not been programmed to match.
It is vital to have a spare Saab key. Learn Additional is especially true for those who live in a rural area, where there are numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership without paying high cost. You can get the replacement key on the spot for less than half of the cost you would spend at a dealership.
Wired key
Saab cars are usually provided with two keys. If you own only one, it is recommended to get an additional key as quickly as you can. This is because if you lose it and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly especially for cars that are used.
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 requires a significant deal of soldering. There is no standardized way to accomplish this, but it's important to plan out the routes you'll use to solder the rows and columns. For this keyboard, there are 5 rows and 17 columns, so there will be 22 microcontroller wires and pins to connect.
After the columns and rows are soldered, it's the time to connect them to key switches. To do this, place a diode across each key switch pin and solder it. This will shield the pins from current, preventing them from being shortened. The diode will only allow the current to flow in a single direction, and it comes with a an indicator in black that indicates the direction in which current will flow.
Sanabria says that a few of the tools that are sold in auto parts stores, such as the Autel MaxiIM IM608PRO and the IM508 can assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into OBD ports and guide 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 for emergency situations however, jumping a battery for newer vehicles may not be the best option. These vehicles have many computers and digital devices that communicate with one another. A surge in voltage while a battery is hooked up to another one could damage these components, rendering your car unable to drive.
Start the vehicle you are using and allow it to run for around two minutes before you connect the cables to the battery that is not working. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clear, unpainted metal surface under 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 create sparks, which could ignite the gasoline in the engine compartment.
Once the cables are connected, you can start the vehicle that has been disabled and let it run for about five minutes before you disconnect them in reverse order. Keep in mind that the battery on the Saab 9-3 gets recharged when you drive, and it may take some time for the battery to come back to its original level. You should consider purchasing another key fob as soon as possible. Replacing the one that works requires the installation and programming of a brand new computer chip.
Replacement case
Many Saab owners have only one key for their vehicle and if they lose it, they'll be charged. The reason for this is that it's expensive to purchase a new key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's recommended to have a spare key in case of theft or any other catastrophe and the most effective way is to buy an extra key as early as you can. Even if the key is "new", it won't work.
The dealer will charge the highest dollar if you only have one working key. We can, however, reset and re-program the computer's EEPROM to prepare it to accept a new key without replacing the whole system. This could help you save money. It's cheaper to do this than waiting until you lose your only key.
