saab 9-3 key fob replacement Key Programming

Saab cars that were built prior to 1994 come with an immobilizer system made up of coded keys. A new transponder is required for the addition of a second key, and special programming. This is usually done by the dealer using a Tech2 diagnostic tool.

The problem is that this can be very costly. This is the reason why you should always keep a spare key in your possession.

Transponder key

The transponder is a type of key with an electronic chip. The chip sends a signal when the key is put in the ignition. The car will then check the signal to determine whether it is identical to that of the key. If the signals match then the car will be able to open and start. This is a great method to stop auto theft and keep your car safe from thieves.

Transponder keys are a popular feature in automobiles, but you should be aware that they are not as secure as traditional keys made of metal. The metal component of a traditional keys can be easily copied and cut, but a transponder has an electronic chip which protects it. This chip contains an individual code that is encoded into the car's system to identify it.

The car will recognize the Saab keyfob, and allow it to turn on. The car can only recognize the key fob when it has an unmodified chip and has been programmed to match. Otherwise, the car would refuse to accept the key and will not start.

It is important to have an extra Saab key. This is particularly true especially if you live in a rural area that is home to numerous car thieves. The good news is that you can obtain a replacement key for your Saab without having to go to an auto dealer and pay the expensive prices that they demand. You can have a replacement key created on the spot for less than half the cost you would spend at dealerships.

Key for Wired

Saab cars are usually supplied with two keys. If you only own one, you need to purchase an additional key as quickly as you can. This is because if the key is lost and the car needs an entirely new CIM and the locking cylinders replaced. This can be costly especially for used vehicles.

The next step is to connect the wires for Lost saab Keys the column and row to the microcontroller. This is the most challenging part of the project and requires a significant amount of soldering. There's no standard way to accomplish this, but it is essential to determine how you will route and solder the columns and rows. For this keyboard, there are 5 rows and 17 columns, which means there will be 22 microcontroller pins and wires to connect.

After the rows and column are joined It is now time to connect the key switches. To do this, put a diode over each key switch pin and solder it. This will shield the pins from current, thus preventing them from being shorted. A diode lets current only flow in one direction. It is equipped with a visible indicator that is black, that shows which way current will flow.

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in some cases program replacement keys and restore Lost Saab keys immobilizer data Sanabria says. The tools connect to the OBD port and guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

The majority of people have a set of jumper cables in their trunk for emergency situations, but jumping a battery in newer automobiles might not be the best choice. These vehicles are equipped with a number of computers and digital devices that communicate with one another. A voltage surge while the battery is connected to another could cause damage to the components and render your car undriveable.

Start the vehicle you are using and allow it to run for around two minutes before connecting the cables to the disabled one. Attach the red clip on the positive terminal of the battery that is good. (It will say "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface underneath the disabled car's hood. The engine block would be a good option. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks that could ignite the gasoline inside the engine compartment.

After the cables have been connected, you should begin the car and let it run for about five minutes. Then disconnect the cables in reverse. The battery in your saab car keys 9-3 will be recharged as you drive. It takes a while for it to recharge again. You should invest in 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

Many Saab owners only have one key for their vehicle and if they lose it, it's going to cost them. The reason for this is that it's costly to buy a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a second key in case of theft or any other catastrophe and the best option is to purchase an additional key as soon as you can. Even when the key is "new", it will not work.

Most locksmiths cannot help you when you only have one working key and the dealer will charge you high fees to replace the computer in your vehicle to make a new replacement. However, we can reset and re-program the computer's EEPROM to accept the new key without having to replace the entire system. This could save you a significant amount of money. It's also cheaper than waiting until you lose your one key.
