Unquestionable Evidence That You Need Saab Ignition Key Replacement

Saab Key Programming

saab keys replacement cars made since 1994 have an immobilizer feature that is based on codes for keys. To add an additional key, you need a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The issue is that it can be very expensive. This is the reason why you should always keep a spare key in your possession.

Transponder key

The transponder is a piece of key that is equipped with an electronic chip. The chip sends a signal when the key is put in the ignition. The car is able to check whether the signal matches with the one on the key. If the signals are in sync it will unlock and begin. This is a great way to guard your car against theft.

Transponder keys may be an increasingly popular feature for automobiles, but they are not as secure as traditional metal keys. While the metal component of a conventional key can be cut and copied the transponder is protected by an electronic chip. The chip has an individual code that is embedded into the car's computer to identify it.

The car will recognize the saab 9-5 key replacement keyfob, and allow it to turn on. But, it's only able to do so if the key fob has a non-modified chip that has been programmed to match it. The car won't start in the event that the key is not programmed to match.

Wired key

Saab cars are usually delivered with two keys. If you have only one, it is recommended to purchase an extra key fob as soon as is possible, because if you lose it the car will require an entirely new CIM unit and the locking cylinders will have to be replaced. This could be expensive especially if you're purchasing a used car.

The next step is connecting the wires for columns and rows to your microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. There is no standard method to accomplish this, but it is essential to determine the route you'll take and solder the rows and columns. For this keyboard, there are 5 rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are soldered together after which it is time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins of the key switch from current and keep them from being shorted. The diode will only allow the current to flow in a single direction, and it has a black band visual indicator that indicates which way the 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 help shop customers or even DIY customers in some cases create replacement keys and restore lost saab key immobilizer information, Sanabria says. The tools plug into the OBD port and 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 trunks for emergencies, but jumping a battery for newer vehicles might not be the best choice. These vehicles are equipped with electronic devices and computers that communicate with one another. A voltage spike when the battery is connected to another can fry the components, rendering your car undriveable.

Connect the cables to the vehicle that is working. Allow it to run for two minutes. Attach the red clip to the positive terminal of the battery that's good. (It will read "POS" or "+".) Attach the other end to a clear, unpainted metal surface under the hood of the affected car. The engine block is a great option. Don't connect the black cable to the negative terminal on the dead battery, since this could cause an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle and let it run for about five minutes. Then, disconnect them in reverse. The battery in your Saab 9-3 will recharge as you drive. It may take a while it to recharge again. You should consider purchasing another key fob as soon as you can. Replacing the one that works requires the installation and programming of a new computer chip.

Replacement Case

Many Saab owners have only one key for their vehicle and if they lose that key, it will cost them. The reason is that it's costly to purchase a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, in addition to programming. It's recommended to have a backup key in case of theft or other disaster, and the best way is to purchase an additional key as early as you can. Even even if the key is "new" it won't work.

The majority of locksmiths won't be able to help in the event that you only have one working key and the dealer will charge for the cost of replacing the computer in your car to make a new replacement. We can, however, reset and re-program your computer's EEPROM to accept a new key without replacing the whole system. This could help you save money. It's cheaper to do this than wait until you lose the sole key.
