5 Killer Quora Answers On Saab Ignition Key Replacement

saab 9-3 key fob programming Key Programming

saab key fob programming cars made since 1994 utilize an immobilizer system that relies on key codes. Adding an extra 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 costly. Always keep an extra set of keys in your possession.

Transponder key

The transponder is a key equipped with an electronic chip. The chip transmits a signal when the key is inserted into the ignition. The car then analyzes the signal to determine whether it matches the one in the key. If the signals are in sync the car will then unlock and begin. This is an excellent way to protect your vehicle from theft.

Transponder keys can be an extremely popular accessory for cars, but they are not as safe as traditional keys made of metal. The metal component of the traditional key is easily cut and copied, whereas a transponder has an electronic chip which protects it. The chip is equipped with an individual code that is programmed into the car's computers to identify it.

When a Saab key fob is used, the car recognizes it and allows it to turn on. But, it's only able to do this if your key fob is unmodified and has a chip that has been programmed to match it. The car won't start in the event that the key is not programmed to match.

It is essential to have an extra Saab key. This is especially true if you live in a rural region where there are a lot of car burglars. The good part is that you can get a replacement key for your Saab without needing to visit a dealer and pay the high costs that they charge. In most instances, you can get an original key made on the spot at a fraction of the price of what you'd pay at the dealer.

Key for Wired

saab replacement key programming cars are usually provided with two keys. If you only have one, it is a good idea to get an additional key fob as soon as is possible in case you lose it, your car will require a new CIM unit, and the locking cylinders will need to be replaced. This can be costly especially if you're purchasing a used vehicle.

The next step is connecting the wires of columns and row to your microcontroller. This is the most laborious part of the project, and it will require a lot of soldering. It's not a common way to go about it, but you should think about how to route and connect each column and row. For this keyboard, there are five rows and 17 columns, so there will be 22 microcontroller pins and wires to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. Solder a diode to each key switch pin. This will shield the pins on the key switch from current and keep them from being shorted. A diode allows 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.

Sanabria says that some of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and IM508 can assist shoppers or DIY users to program replacement keys and restore immobilizer data. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the vehicle's computer.

Jump starting the battery

A majority of people keep an assortment of tools in their trunk to jump start a car in an emergency, but it may not be a good idea for vehicles that are newer. These vehicles are equipped with numerous computers and digital devices which communicate with one another. A surge of voltage when a battery is connected to another battery could damage the components, rendering your car undriveable.

Connect the cables to the vehicle that is working. Let it 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 of the black cable to a clean, unpainted metal surface beneath the damaged car's hood--the engine block is a good option. Don't connect the black cable to the negative terminal of the dead battery, since this could cause an ignition that ignites the gasoline in the engine bay.

After the cables have been connected, start the vehicle and let it run for approximately five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 will be recharged as you drive. It will take some time for it to return to its original state. It is a good idea to purchase a spare key fob as soon as you can, because replacing the sole working one requires the installation of a new computer module and special programming to convince it that your missing keys are not trying to steal the car.

Replacement Case

Many Saab ignition key replacement owners only have one key for their car and if they lose that key, it will cost them. The reason for this is that it's not inexpensive to add 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 spare key in case of theft or any other catastrophe and the most effective way is to purchase an additional key as soon as you are able to. Don't purchase a used key even when it's "new." Keys that are claimed-new from aftermarket sellers will not perform and are almost certain to fail in the crucial moment.

The dealer will charge the highest dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a replacement key without the need to replace the entire system. That can save you lots of money. It's also cheaper than waiting until you lose your sole key.
