Saab Key Programming

Saab cars built since 1994 feature an immobilizer that relies on keys that are coded. 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.

It can be costly. You should always keep a spare set of keys on hand.

Transponder key

The transponder can be described as a key that is equipped with an electronic chip. The chip sends a signal when the key is inserted into the ignition. The car will then check the signal to see if it matches the one on the key. If the signals match it will open itself and begin. This is a great way to avoid auto theft and keep your vehicle safe from thieves.

Transponder keys can be an increasingly popular feature for automobiles, but they are not as secure as traditional keys made of metal. While the metal part of a traditional key could be cut and copied the transponder is protected by an electronic chip. This chip contains an unique code that is programmed into a car's computers in order to identify it.

The car will recognize the saab 9-3 key keyfob and allow it to be turned on. However, it can only do this if the key fob is equipped with a chip that is not modified that has been programmed to match the original. The car won't start if the key is not programmed to match.

It's crucial to ensure that you have a spare key for your Saab. This is especially true for those who live in a rural area, where there are many car thieves. The good thing is that you can obtain a replacement key for your Saab without having to go to a dealership and pay the high costs that they ask. You can have an original key made on the spot for less than half what you would spend at an auto dealer.

Wired key

saab ignition key (Hatch-Lerche.Blogbright.net) cars are usually provided with two keys. If you have only one, you need to purchase an additional key as quickly as you can. This is because if you lose it, the car will need an entirely new CIM and the locking cylinders replaced. This can be costly particularly if you are buying a second-hand car.

The next step is to connect the row and columns wires to your microcontroller. This is the most laborious part of the project and it will require a lot of soldering. There isn't a standard method to go about it, however, you should think about how to connect and solder each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller wires and pins that you need to connect.

After the rows and column are joined then it's time to connect the key switches. To do this you must place a diode over each pin on the key switch and solder it. This will shield the pins on the key switch from current and stop them from being shorted. A diode only allows current to flow in one direction, and has a the black band as a visual indicator that indicates which way the current will flow.

A few of the tools that are available at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- may assist customers at the shop or DIY customers in some cases programme replacement keys and recover the lost immobilizer's data, Sanabria says. The tools connect to the OBD port and automatically guide the user through the process, making it more simple than replacing the computer in the vehicle.

Jumpstarting the battery

The majority of people have a set of jumper cables in their trunks to use in an emergency, but jumping a battery on newer vehicles might not be the most efficient option. These vehicles are equipped with many digital and computer systems that communicate with one another. A surge in voltage when a 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 of the good battery. (It will read "POS" or "+".) Attach the other end to a clean and unpainted metal surface under the hood of the damaged vehicle. The engine block is a great option. The black cable should not be connected to the negative terminal of the dead battery. This could result in a spark, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, start the vehicle that has been disabled and let it run for about five minutes before you disconnect them in reverse order. Remember that the battery on the Saab 9-3 gets recharged when you drive, so it will take a while to get the battery back down again. It's a good idea to purchase a spare fob as soon as you can, since replacing the sole working one requires the installation of a brand new computer module and special programming to convince the system that your lost saab key keys aren't trying to steal the car.

Replacement case

Many saab key replacement owners only have one key for their car and if they lose that they'll be charged. It's costly to add keys and will require replacing the CIM or TWICE for older models. It's best to have a second key in the event of theft or other disaster, and the best way is to purchase an additional key as soon as you are able to. However, don't purchase a secondhand key even the case that it's "new." Keys that are claimed-new purchased from third-party sellers won't work and are almost guaranteed to fail at the critical moment.

The dealer will charge you the most expensive dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to get it ready to accept a new key without the need to replace the entire system. This could save you a lot of money. It's much cheaper than waiting until you loose the only key.
