Saab Key Programming

saab key fob cars made since 1994 have an immobilizer system that is based on codes for keys. The addition of a key requires a new transponder and 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 in your possession.

Transponder key

The transponder key is a key equipped with an electronic chip. It sends a signal back to the car when it is placed in the ignition. The car is able to check whether the signal is the same as the one on the key. If the signals match, the car will unlock and begin. This is a great method to prevent auto theft and keep your vehicle secure from thieves.

Transponder keys are a popular feature in vehicles, but you should be aware they are not as secure as traditional metal keys. While the metal part of a traditional key could be cut and copied, a transponder is protected by an electronic chip. The chip contains a unique code which is programmed into a Car key cutting and programming near me's computers in order to identify it.

The car will recognize the Saab keyfob and permit it to be turned on. The car can only recognize the key fob when it has a chip that is unmodified and has been programmed to match. The car will not start in the event that the key is not programmed to match.

It is essential to ensure that you have an extra key for your Saab. This is particularly important especially if you live in a rural region that has many car thieves. The good news is that it's possible to find a replacement key for saab 93 key to your saab keys replacement without having to go to an auto dealership and pay the hefty prices that they demand. In the majority of cases, you can have a new key created on-the-spot at a fraction of the price of what you would pay at dealerships.

Wired key

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

The next step is to wire the row and column wires to the microcontroller. This is the most challenging part of the project and will require a good deal of soldering. It's not a common way to go about it, but you must determine how to program saab 9-3 key fob to route and solder each column and row. For this keyboard, there are five rows and 17 columns. This means there will be 22 microcontroller pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to the key switches. Solder a diode to each key switch pin. This will shield the pins from current, thus preventing them from being shorted. A 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.

A few of the tools that are available at auto parts stores -- such as the Autel MaxiIM IM608 PRO and IM508 -- could help customers in the shop, or even DIY customers in certain cases program replacement keys and restore lost immobilizer information, Sanabria says. The tools connect to the OBD port and guide the user through the process, making it easier than replacing the computer inside the vehicle.

Jumpstarting the battery

Most people keep a few sets of jumper cables in their trunk for emergencies, but jumping a battery on modern cars might not be the best option. These cars are equipped with a variety of electronic devices and computers that communicate with one another. A surge of voltage when a battery is connected to another can fry the components and render your vehicle unusable.

Connect the cables to the vehicle operating. Let it run for two minutes. Attach the red clip on the positive terminal of the battery that is good. (It will read "POS" or "+".) Attach the other end of the black cable to an unpainted, clean metal surface under the disabled vehicle's hood. An engine block is a good option. The black cable should not be connected to the negative terminal of the dead battery. This could trigger sparks that could ignite the gasoline inside the engine compartment.

Once the cables are connected, you need to start the vehicle and allow it to run for around five minutes. Then, disconnect them in reverse. The battery in the Saab 9-3 will charge as you drive. It takes a while for it to return to its original state. You should consider purchasing an additional key fob as soon as possible. Replacing the original one that works requires the installation and programming of a new computer chip.

Replacement Case

Many saab key programmer owners have only one key for their vehicle and if they lose it, the cost will be. It's expensive to add a key and requires replacing the CIM or TWICE in the case of older models. In the event of theft, or any other catastrophe it is recommended to have a spare key. Don't purchase a used key, even the case that it's "new." Keys that are claimed as new from sellers selling aftermarket keys won't perform and are almost certain to fail at the crucial moment.

The dealer will charge you the highest dollar if you only have one working key. We can, however, reset and re-program the computer's EEPROM to accept a new key without replacing the whole system. This can save you a lot of money. It's also a lot cheaper than waiting until you lose your one key.
