7 Things About Saab Ignition Key Replacement You'll Kick Yourself For Not Knowing
Saab Key Programming

Saab cars manufactured from 1994 have an immobilizer system based on a set of keys. To add an additional key, you need an entirely new transponder and programming. This is usually done by the dealer using a Tech2 diagnostic tool.

This can be expensive. It is always advisable to keep an extra set of keys 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 then checks to see whether the signal is the same as the one on the key. If the signals are in sync then the car will be able to unlock and begin. This is a great way to stop auto theft and keep your car secure from thieves.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as safe as traditional metal keys. The metal part of the traditional keys can be easily cut and copied, whereas the transponder is protected by an electronic chip that guards it. This chip has an unique code that is programmed into the car's computers to identify it.

The car will recognize the Saab keyfob and allow it to turn on. The car will only recognize the key fob when it has an unmodified chip and programmed to match. The car will not start in the event that the key has not been programmed to match.

It is crucial to have an extra Saab key. This is particularly important when you live in a rural region that has numerous car thieves. You can get a new key for your Saab by going to the dealership, without having to pay their expensive costs. You can get a replacement key made on the spot for less than half the price you'd spend at dealerships.

Wired key

Saab cars are usually delivered with two keys. If you own only one, you should purchase an additional key as soon as you can. how to open a saab 93 without a key is because, if it's lost and the car is damaged, it will require an entirely new CIM and the locking cylinders replaced. This could be expensive especially if buying a second-hand car.

The next step is to connect the row and column wires to the microcontroller. This is the most difficult part of the project and will require a good amount of soldering. There is no standardized way to accomplish this, however it's important to plan out the route you'll take and solder the rows and columns. There are 22 microcontroller wires and pins that you can connect for this keyboard. It has five rows and 17 column.

After the columns and rows are soldered, it's time to connect them to key switches. To do this, place a diode across each pin on the key switch and solder it. This will shield the pins from current, preventing them from being shorted. A diode lets current only flow in one direction. It has a visual indicator with a black band that shows the direction in which the current will flow.

Sanabria states that a number of the tools sold in auto parts stores, including the Autel MaxiIM IM608PRO and the IM508, can help shoppers or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and guide the user through the process, making it more simple than replacing the computer in the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk for emergencies however, jumping a battery on modern automobiles might not be the best option. These cars are equipped with a variety of electronic devices and computers that communicate with each other. A voltage surge while the battery is connected to another battery could fry these components, rendering your car undriveable.

Start the vehicle that is working and let it run for about two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the good battery (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface under the hood of the affected car. The engine block is a good option. Don't connect the black cable to the negative terminal on the dead battery as this could cause an ignition that ignites the gasoline in the engine bay.


After the cables have been connected, you should start the vehicle and let it run for about five minutes. Then disconnect the cables in reverse. The battery in your Saab 9-3 will be recharged while you drive. It will take some time for it to recharge again. It's a good idea purchase a spare key fob as soon as you can, because replacing the only functioning one requires the installation of a new computer module and special programming to convince it that the lost keys aren't in the process of trying to steal the car.

Replacement case

Saab owners usually have only one car key, and if that is lost, they will be charged. The reason for this is that it's costly to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It's best to have a second key in case of theft or any other catastrophe, and the best way is to purchase an additional key as soon as you are able to. Even when the key is "new", it won't work.

The majority of locksmiths won't be able to help when you only have one working key and the dealer will charge you top dollar to replace the computer in your vehicle for a replacement. However, we can reset and reprogram the computer's EEPROM in order to prepare it to accept an alternative key without replacing the entire system. This could help you save money. It's also cheaper than waiting until you lose the only key.
