Saab Key Programming

Saab cars made since 1994 feature an immobilizer system that is based on a set of keys. To add an additional key, you need a new transponder, as well as special programming. This is usually handled by the dealer using the Tech2 diagnostic tool.

The issue is that this could be quite costly. This is why it is important to always have a spare key available.

Transponder key

The transponder is a key that is 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 then the car will be able to unlock and start. This is a great method to deter car theft and keep your car secure from thieves.

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

The car will recognize the Saab keyfob, and allow it to be turned 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 is not programmed to match.

It is essential to ensure that you have an extra key for your Saab. This is especially important for those who live in a rural location that has many car thieves. The good news is that it's possible to get a replacement key for your saab 93 key replacement without needing to visit an auto dealer and pay the hefty prices that they ask. In most instances, you can get a brand new key made right on the spot for less than half the price of what you'd pay at a dealer.

Key for Wired

Saab cars are usually supplied with two keys. If you have only one, you should purchase an extra key as soon as you can. This is because, if it's lost, the car will need an entirely new CIM and the locking cylinders replaced. This could be expensive, especially if you are purchasing a used car.

The next step is to connect the wires for the column and row to the microcontroller. This is the most challenging part of the project and will require a large deal of soldering. It's not a common way to go about it, but you must consider how to program saab 9-3 key fob 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 pins and wires to connect.

After the columns and rows are soldered, it's time to connect them to key switches. Solder a diode on each key switch pin. This will shield the key switch pins from current and also prevent them from being shorted. A diode permits current to only flow in one direction. It features a visual indicator, a black band, that shows the direction in which the current will flow.

Sanabria states that a number of the tools that are sold in auto parts stores, like the Autel MaxiIM IM608PRO and IM508 are able to assist customers shopping or DIY users to program replacement keys and restore the immobilizer's data. The tools plug into the OBD port and 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 a set in their trunks to jump start a vehicle in an emergency, however it might not be a good idea for vehicles that are newer. These vehicles are equipped with digital and computer systems that communicate with one another. A voltage spike when the battery is connected to another could cause damage to the components, rendering your car undriveable.

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 have "POS" or "+" on it). Attach the other end to a clean, unpainted metal surface under the hood of your disabled vehicle. The engine block is a good choice. Don't connect the black cable to the negative terminal on the dead battery as it could spark a spark that ignites the gasoline in the engine bay.

Once the cables are connected, turn on the disabled vehicle and let it run for about five minutes before disconnecting the cables in reverse order. Keep in mind that the battery on your Saab 9-3 is recharged while you drive, so it may take some time to get the battery back to normal. It is a good idea to purchase a spare key fob as soon as you can, because replacing the one that works requires the installation of a new computer module and special programming to convince the system that your lost saab keys keys are not trying to steal the car.

Replacement case

Many saab ignition key replacement - More inspiring ideas - owners only have one key for their car and if they lose that it's going to cost them. It's expensive to add an additional key and it requires replacing the CIM or TWICE for older models. It is best to have a second key in the event of theft or other disaster and the best option is to purchase an extra key as quickly as you can. But don't buy a used key even if it's "new." Keys that are claimed to be new purchased from third-party sellers won't work and are likely to fail in the most critical moment.

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