Saab Key Programming

saab car keys cars made since 1994 come with an immobilizer system that is based on codes for keys. To add an additional key, you need a new transponder, as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

This can be expensive. Always keep a spare set of keys available.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car checks to see whether the signal is the same as the one on the key. If the signals match it will open and start. This is a great way to stop car theft and keep your vehicle safe from thieves.

Transponder keys may be an increasingly popular feature for cars, but they are not as secure as traditional keys made of metal. While the metal component of a traditional key may be cut and copied however, a transponder is secured by an electronic chip. This chip has an unique code that is programmed into the car's computers to identify it.

When a saab 9-3 key fob replacement key fob is used, the car recognizes it and allows it to turn on. The car will only recognize the key fob if it is equipped with a chip that is unmodified and programmed to match. The car will not start in the event that the key has not been programmed to match.

It is essential to ensure that you have an extra key for your saab key replacement cost. This is particularly important when you live in a rural region where there are a lot of car burglars. You can obtain a replacement key for your Saab by going to the dealership, without having to pay their pricey costs. In the majority of instances, you can get an original key made on the spot at a fraction of the cost of what you'd pay at dealerships.

Wired key

Saab cars are typically delivered with two keys. If you only have one, it is best to acquire an extra key fob as soon as is possible, because if you lose it the car will require an entirely new CIM unit, and the locking cylinders will need to be replaced. This can be costly especially for cars that are used.

The next step is connecting the wires for columns and row to your microcontroller. This is the most difficult part of the project and will require a great deal of soldering. There isn't a standard way to accomplish this, however it is essential to determine the routes you'll use to solder the rows and columns. For this keyboard, there are five rows and 17 columns. This means 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 to each key switch pin. This will protect the key switch pins from current and keep them from being shorted. A diode only allows the flow of current to be in one direction, and it comes with a an indicator of black color that indicates the direction current will flow.

Some of the tools available at auto parts storeslike the Autel MaxiIM IM608 PRO and IM508 -- can help shop customers or even 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 guide the user through the procedure, making it much easier than replacing the computer inside the vehicle.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency however, jumping a battery on newer vehicles may not be the best choice. These vehicles have many digital and electronic devices that communicate with one another. A voltage surge while the battery is connected to another could cause damage to these components and render your vehicle unable to drive.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that's good. (It will say "POS" or "+".) Attach the other end to a clean, unpainted metal surface beneath the hood of the disabled vehicle. The engine block is an excellent option. Do not connect the black cable to the negative terminal on the dead battery as it could spark an ignition spark that ignites the gasoline in the engine bay.

Once the cables are connected, you can start the vehicle you are not using and allow it to run for around five minutes before disconnecting them in reverse order. The battery in the saab car keys 9-3 will charge while you drive. It takes a while for it to drop back down. You should invest in a second key fob, as soon as possible. Replacing the original one that works requires the installation and programming of a brand new computer chip.

Replacement case

Saab owners often only have one car key, and if it is lost, they'll be charged. The reason for this is that it's expensive to add a new key, and it requires replacing the CIM (Column Integration Module) or TWICE on older models, as well as programming. It's recommended to have a second key in the event of theft or other disaster and the most effective way is to purchase an additional key as soon as you can. Even when the key is "new", it won't work.

Most locksmiths cannot help you with a single working key, and the dealer will charge high fees to replace the computer in your car to make a replacement. However, we can reset and re-program your computer's EEPROM to prepare it to accept an alternative key without replacing the whole system. This could save you a great deal of money. It's also cheaper than waiting until you lose your one key.
