saab 9-3 key programming Key Programming

Saab cars that were built prior to 1994 have an immobilizer system made up of coded keys. In order to add a second key, it requires a new transponder, as well as special programming. This is usually handled by the dealer using a Tech2 diagnostic tool.

This can be expensive. This is the reason why you should always have a spare key available.

Transponder key

The transponder is a type of key that has an electronic chip. The chip sends a signal when the key is inserted in the ignition. The car will check to see whether the signal is the same as the one on the key. If the signals are identical the car will then unlock itself and begin. This is a great method to deter auto theft and keep your car secure from thieves.

Transponder keys may be an extremely popular accessory for cars, but they're not as secure as traditional keys made of metal. The metal component of the traditional key can easily be cut and copied, however transponders have an electronic chip that guards it. This chip contains an unique code which is programmed into a car's computer order 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 is equipped with a chip that is not modified that has been programmed to match. The car will not start if the key is not programmed to match.

It is vital to have an extra saab ignition key key. This is especially true if you live in a rural location where there are numerous car thieves. The good thing is that you can find a replacement key to your saab car keys without having to go to a dealership and pay the high prices that they demand. In the majority of cases, you can have a new key made on-the-spot at a fraction of the price of what you'd pay at dealerships.

Key for Wired

Saab cars are typically delivered with two keys. If you only have one, it's a good idea to get an additional key fob as quickly as you can as if you lose it, your car will require a new CIM unit, and the locking cylinders will have to be replaced. This can be expensive, especially for used cars.

The next step is to connect the wires of columns and row to your microcontroller. This is the most difficult part of the project and will require a good deal of soldering. There isn't a standard method to do it, but you need to consider how you will connect and solder each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are soldered together then it's time to connect the key switches. Solder a diode on each key switch pin. This will shield the pins that are used for key switches from current and keep them from being shorted. A diode permits current to only flow in one direction. It features a visual indicator of a black line that indicates the direction in which current will flow.

Some of the tools you can find at auto parts stores- such as the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain instances program replacement keys and restore the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jump-starting the battery

A lot of people keep an item in their trunks to jump start a vehicle in the event of an emergency, but it may not be a good idea for cars with more modern technology. These cars have a variety of computers and digital devices that communicate with one another. A voltage surge while the battery is connected to another one could damage the components and render your car undriveable.

Start the working vehicle and allow it to run for approximately two minutes before connecting the cables to the disabled 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 underneath the car's hood--the engine block is a good choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which would ignite the gasoline that is in the engine compartment.

Once the cables are connected the vehicle that has been disabled and let it run for approximately five minutes before disconnecting them in reverse order. The battery in your saab 9 3 key replacement ignition key (just click the following website) 9-3 is recharged while you drive. It will take some time for it to fall back. You should purchase an additional key fob as soon as you can. The replacement of the one that works requires the installation and programming of a brand new computer chip.

Replacement case

Many saab car keys owners have only one key for their car and if they lose it, key, it will cost them. The reason is that it's expensive to add a new key, and this involves replacing the CIM (Column Integration Module) or TWICE on older models, and programming. It is recommended to have a backup key in case of theft or any other catastrophe, and the best way is to purchase a second key as soon as you are able to. Even when the key is "new", it will not work.

The dealer will charge you top dollar if you have only one working key. We can reset and reprogram the computer's EEEPROM for it to accept a new key without the need to replace the entire system. This can save you a significant amount of money. It's more affordable rather than wait until you lose the sole key.
