Is Tech Making Saab Ignition Key Replacement Better Or Worse?
Saab Key Programming
Saab cars manufactured since 1994 utilize an immobilizer system that is based on keys that are coded. A new transponder is required for addition of a second key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.
The problem is that it can be very 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 sends a signal to car when it is placed in the ignition. The car will check to see whether the signal matches with the one on the key. If the signals match the car will then unlock and begin. This is a great method to stop car theft and keep your vehicle secure from thieves.
Transponder keys are an increasingly popular feature for cars, but they're not as secure as traditional metal keys. While the metal component of a traditional key could be cut and copied however, a transponder is secured by an electronic chip. The chip is a unique code which is programmed into the car's computer in order to identify it.
The car will recognize the Saab keyfob, and allow it to be turned on. The car can only recognize the key fob when it has an unmodified chip and programmed to match. Otherwise, the car will reject the key and won't start.

Wired key
Saab cars are usually delivered with two keys. If you only have one, you should purchase an additional key as soon as you can. This is because if you lose it, the car will need a new CIM and the locking cylinders replaced. This could be expensive particularly if you are purchasing a used vehicle.
The next step is to connect the wires for columns and rows to your microcontroller. This is the most challenging part of the project and will require a great amount of soldering. There is lost saab keys www.g28carkeys.co.uk to accomplish this, but it's important to plan out the routes you'll use to solder the rows and columns. There are 22 microcontroller wires as well as pins to connect for this keyboard. It has 5 rows and 17 columns.
After the columns and rows are joined, it is time to connect the key switches. To do this, place a diode across each pin on the key switch and solder it. This will protect the pins that are used for key switches from current and also prevent them from being shorted. The diode will only allow the current to flow in a single direction, and it comes with a a black band visual indicator that indicates 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 -- can assist customers at the shop or DIY users in some cases program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and automatically guide the customer through the procedure, making it simpler than replacing the computer in the vehicle.
Jump-starting the battery
The majority of people have an item in their trunks to jump start a vehicle in the event of an emergency, but it may not be a good idea for newer cars. These vehicles have many digital and computer systems that communicate with each other. A voltage surge when a battery is connected to another can fry the components making your car inoperable.
Connect the cables to the vehicle operating. 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 clean, unpainted metal surface under the hood of the affected vehicle. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal on the dead battery, as this could cause an ignition source that ignites gasoline in the engine bay.
Once the cables are connected, turn on the vehicle you are not using and let it run for approximately five minutes before you disconnect the cables in reverse order. Be aware that the battery in the Saab 9-3 will be charged when you drive, so it may take some time to get the battery back to normal. It is recommended to purchase an additional key fob as soon as possible. The replacement of the one that works requires the installation and programming of a new computer chip.
Replacement Case
Saab owners often only have one car key, and if that is lost, they will 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, in addition to programming. In the event of theft or any other calamity it is recommended to have a spare key. However, don't purchase a secondhand key, even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't be effective and are almost guaranteed to fail in the crucial moment.
