saab key programming (please click Compravivienda)

Saab cars that were built prior to 1994 have an immobilizer feature made up of coded keys. To add an additional key, you need a new transponder and special programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that this could be quite costly. Always keep an extra set of keys available.

Transponder key

The transponder is a type of key equipped with an electronic chip. The chip transmits a signal when the key is placed into the ignition. The car will check to see whether the signal matches with the one on the key. If the signals match the car will then unlock and begin. This is a great method to avoid car theft and keep your vehicle safe from thieves.

Transponder keys are an increasingly popular feature in vehicles, but it is important to know that they are not as secure as classic keys made of metal. While the metal component of a traditional key may be cut and copied but a transponder key is protected by an electronic chip. This chip has a unique 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. However, it is only able to do so if the key fob is unmodified and has a chip that has been programmed to match it. The car will not start in the event that the key has not been programmed to match.

It is important to have an extra saab spare key key. This is particularly important for those who live in a rural area with numerous car thieves. You can obtain a replacement key for your Saab by visiting the dealership and not paying their pricey prices. In most instances, you can get a new key made on-the-spot at a fraction of the cost you would pay at dealerships.

Key for Wired

Saab cars are usually delivered with two keys. If you have only one, it's an ideal idea to purchase an extra key fob as soon as you can since if you lose it, your car will require an entirely new CIM unit and the locking cylinders have to be replaced. This can be expensive particularly for used cars.

The next step is to connect the wires for columns and row to your microcontroller. This is the most tedious part of the project and will require a lot of soldering. It's not a standard way to do it, but you should consider how you will 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 that you need to connect.

Once the rows and columns are soldered, it's time to connect them to key switches. To do this you must place a diode over each pin on the key switch and solder it. This will shield the key switch pins from current and also prevent them from being shorted. The diode allows current to only flow in only one direction. It has a visual indicator that is black, that shows which way current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can aid shop customers or DIY customers in certain cases program replacement keys and restore lost immobilizer data Sanabria says. The tools plug into the OBD port and guide the user through the process, making it easier than replacing the computer in the vehicle.

Jump starting the battery

A lot of people keep a set in their trunk to jump-start a car in case of emergency, but it might not be the best option for vehicles with newer technology. These vehicles have many digital and electronic devices that communicate with each other. A surge in voltage when the battery is connected to another can fry the components making your car inoperable.

Connect the cables to the vehicle that is operating. Let it run for two minutes. Attach the red clip to the positive terminal on the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface beneath the hood of the damaged vehicle. The engine block is an excellent alternative. Don't connect the black cable to the negative terminal on the dead battery, since it could spark an ignition source that ignites gasoline in the engine bay.

After the cables have been connected, start the car and let it run for about five minutes. Then disconnect them in reverse. The battery in your Saab 9-3 is recharged while you drive. It takes a while for it to fall back. It's a good idea invest in a spare key fob as soon as you can, since replacing the one that works requires the installation of a new computer module and special programming to convince it that the lost saab keys keys are not trying to steal the car.

Replacement case

Many Saab owners only have one key for their car and if they lose that the cost will be. The reason is that it's not inexpensive to replace a key, and it involves replacing the CIM (Column Integration Module) or TWICE on older models, plus programming. It's best to have a spare key in case of theft or other disaster and the best option is to buy an extra key as soon as you are able to. However, don't purchase a secondhand key even if it's "new." Keys that are claimed-new from aftermarket sellers will not work and are almost guaranteed to fail in the crucial moment.

Most locksmiths can't help you if you have only one working key, and the dealer will charge top dollar to replace the computer in your vehicle to create a replacement saab key. We can reset and reprogram the computer's EEEPROM in order for it to accept a new key without replacing the entire system. This can save you a significant amount of money. It's much cheaper rather than wait until you loose the only key.
