Saab cars made since 1994 come with an immobilizer system that is based on codes for keys. A new transponder is required in order to enable the addition of an extra key, as well as special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

It can be costly. This is the reason why you should always have a spare key at hand.

Transponder key

The transponder key is a key equipped with an electronic chip. It transmits a signal to the car when it is inserted into the ignition. The car then examines the signal to determine whether it matches the one on the key. If the signals are in sync, the car will unlock and start. This is a great method to protect your car from theft.

Transponder keys are an increasingly popular feature in automobiles, however you should be aware that they aren't as secure as classic metal keys. The metal part of the traditional keys can be easily cut and copied, however transponders are protected by an electronic chip which protects it. The chip has an individual code that is embedded 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. However, it will only do this if the fob has an unmodified chip that has been programmed to match the original. The car won't start in the event that the key is not programmed to match.

It is crucial to have an extra saab key replacement key. This is particularly important for those who live in a rural region that has many car thieves. You can get a brand new key for your Saab by going to the dealership, without having to pay their pricey cost. In the majority of cases, you can have a new key created on-the-spot for less than half the cost you'd pay at dealerships.

Key for Wired

Saab cars typically come with two keys when they're new. If you only have one, it's an ideal idea to purchase an additional key fob as quickly as you can as if you lose it, the car will require the replacement of a CIM unit and the locking cylinders need to be replaced. This can be costly especially if buying a second-hand car.

The next step is to connect the wires for columns and row to your microcontroller. This is the most difficult part of the project and requires a significant deal of soldering. It's not a standard way to go about it, but you need to think about how to route and solder each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It includes 5 rows and 17 column.

After the rows and column are soldered together It is now time to connect the key switches. To do this, place an inverter over each pin on the key switch and solder it. This will shield the key switch pins from current and stop them from being shorted. A diode permits current to only flow in only one direction. It comes with a visual indicator with a black band that shows which way current will flow.

Some of the tools you can find at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 – could aid shop customers or DIY users in some cases create replacement keys and restore the lost immobilizer's data, Sanabria says. The tools plug into OBD ports and guide the user through each step, making the process easier than replacing the vehicle's computer.

Jump-starting the battery

A lot of people keep a set of jumper cables in their trunks for emergencies, but jumping a battery on newer automobiles might not be the most efficient option. These vehicles are equipped with numerous computers and digital devices which communicate with each other. A voltage surge when the battery is connected to another could cause damage to the components, rendering your car undriveable.

Connect the cables to the vehicle operating. Let it run for two minutes. 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 disabled car. The engine block is an excellent alternative. Do not connect the black cable to the negative terminal of the dead battery because this could cause an ignition source that ignites gasoline in the engine bay.

Once the cables are connected, you need to start the vehicle and let it run for about five minutes. Then, disconnect the cables in reverse. The battery in your saab ignition key Replacement 9-3 is recharged as you drive. It will take a while 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 brand new computer module and a special program to convince it that the lost keys are not trying to steal the car.

Replacement case

Many Saab owners have only one key for their vehicle and if they lose it, it's going to cost them. The reason for this is that it's not inexpensive to add 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 backup key in the event of theft or other disaster the best solution is to purchase an extra key as quickly as you can. Don't purchase a used key, even the case that it's “new.” Claimed-new keys from sellers selling aftermarket keys won't work and are likely to fail at the crucial moment.

The dealer will charge you top dollar for only one working key. We can, however, reset and reprogram the computer's EEPROM to accept an alternative key without replacing the whole system. This can save you a significant amount of money. It's also less expensive than waiting until you lose your one key.
