Saab Key Programming

Saab cars built since about 1994 come with an immobilizer system made up of coded keys. A new transponder is required for the addition of an additional key, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

The problem is that this can be quite costly. You should always keep an extra set of keys available.

Transponder key

The transponder is a key that is equipped with an electronic chip. This chip sends a signal when the key is placed into the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals match, the car will unlock itself and begin. This is a fantastic way to safeguard your car from theft.

Transponder keys are a common feature in automobiles, but it is important to know that they're not as secure as traditional keys made of metal. While the metal part of a traditional key can be cut and copied but a transponder key is protected by an electronic chip. The chip contains a unique code which is programmed into a car's computer order to identify it.

When a saab ignition key key fob is used, the car recognizes it and allows it to turn on. The car can only recognize the key fob when it has an unmodified chip and has been programmed to match. The car won't start when the key isn't programmed to match.

It is important to have an extra Saab key. This is particularly true when you live in a rural location that has many car thieves. The good news is that you can find a new key for your Saab without having to go to an auto dealer and pay the high costs that they charge. You can have a replacement key made on the spot for less than half the cost you would spend at a dealership.

Wired key

saab replacement key programming cars typically come with two keys when they are new. If you have only one, it is an ideal idea to purchase an extra key fob as soon as is possible in case you lose it the car will require an entirely new CIM unit and the locking cylinders have to be replaced. This can be costly particularly for used cars.

The next step is connecting the row and columns wires to your microcontroller. This is the most challenging part of the project and will require a good amount of soldering. It's not a common way to go about it, but you need to 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 wires and pins to connect.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will protect the pins from current and prevent them from being shorted. A diode allows current to only flow in one direction. It has a visual indicator with a black band that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 Pro and IM508 -- could help customers in the shop, or even DIY customers in certain instances program replacement keys and restore lost immobilizer data Sanabria says. The tools connect to the OBD port and saab key Programming 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 however, jumping a battery for newer vehicles might not be the best choice. These cars are equipped with a variety of computers and digital devices which communicate with each other. A surge of voltage when a battery is connected to another could cause damage to the components and render your vehicle unusable.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the non-working one. Attach the red clip to the positive terminal on the good battery (it will have "POS" or "+" on it). Attach the other end of the black cable to a clean, unpainted metal surface under the disabled car's hood--the engine block is an excellent choice. Do not connect the black cable to the negative terminal of the dead battery, since it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected the disabled vehicle and allow it to run for around five minutes before disconnecting them in reverse order. The battery in your Saab 9-3 is recharged as you drive. It will take a while for it to fall back. You should consider purchasing an additional key fob as soon as you can. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement Case

Saab owners usually only have one car key, and if that is lost, they will be charged. The reason for this is that it's costly to buy a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, and Saab Key Programming programming. It is best to have a spare key in case of theft or any other catastrophe, and the best way is to purchase a second key as soon as you can. But don't buy a used key, even it's "new." Keys that are claimed to be new purchased from third-party sellers won't work and are likely to fail at the critical moment.

Most locksmiths aren't able to help in the event that you only have one working key, and the dealer will charge you high fees to replace the computer in your vehicle to make a replacement. We can, however, reset and reprogram the computer's EEPROM in order to prepare it to accept an alternative key without replacing the entire system. This could save you a great deal of money. It's also much less expensive than waiting until you lose your sole key.
