Saab Ignition Key Key Programming

saab 9-3 key fob replacement cars manufactured since 1994 come with an immobilizer system based on coded keys. In order to add a second key, it requires the purchase of a new transponder as well as special programming. This is usually done by the dealer using the Tech2 diagnostic tool.

The problem is that this can be very costly. You should always keep a spare set of keys at hand.

Transponder key

The transponder key comes equipped with an electronic chip. It sends a signal to car when it is inserted 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 way to deter car theft and keep your vehicle secure from thieves.

Transponder keys may be a popular addition to cars, but they're not as secure as traditional keys made of metal. The metal component of the traditional keys can be easily copied and cut, but the transponder is protected by an electronic chip that safeguards it. This chip contains an unique code which is programmed into the car's computer in order to identify it.

When a Saab key fob is used the car recognizes it and allows 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 is not programmed to match.

It's important to make sure that you have an extra key for your Saab. This is especially true for those who live in a rural location where there are a lot of car burglars. You can obtain a replacement key for your saab 9-3 key not accepted contact service by visiting the dealership and not paying their high costs. You can get the replacement key on the spot for less than half of what you would spend at a dealership.

Wired key

saab key fob programming cars typically come with two keys when they're new. If you only own one, you need to purchase an additional key as fast as you can. This is because if the key is lost and the car is damaged, it will require a new CIM and the locking cylinders replaced. This can be expensive especially for cars that are used.

The next step is to connect the wires for the column and row to the microcontroller. This is the most difficult part of the project and will require a large amount of soldering. It's not a standard way to do it, but you should plan how to route and connect each column and row. For this keyboard, there are 5 rows and 17 columns. So there will be 22 microcontroller pins and wires to connect.

After the columns and rows are joined after which it is time to connect the key switches. Solder a diode to each key switch pin. This will protect the key switch pins from current and stop them from being shorted. A diode lets current only flow in only one direction. It features a visual indicator of a black line that indicates the direction in which current will flow.

Some of the tools offered at auto parts stores -like the Autel MaxiIM IM608 PRO and IM508 -- can help customers in the shop, or even DIY customers in certain instances create replacement key for saab 93 keys and restore the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and guide the customer through each step and make the process more straightforward than replacing the car's computer.

Jump-starting the battery

A lot of people keep an item in their trunk to jump start a car in case of emergency, but it might not be a good option for vehicles with newer technology. These vehicles are equipped with numerous digital and computer systems that communicate with each other. A surge in voltage while a battery is hooked up to another can fry these components, rendering your car unable to drive.

Start the vehicle that is working and allow it to run for around two minutes before you connect the cables to the non-working one. Attach the red clip to the positive terminal of the battery that is good (it will have "POS" or "+" on it). Attach the other end to a clean and unpainted metal surface under the hood of the disabled vehicle. The engine block is a good alternative. Don't connect the black cable to the negative terminal of the dead battery as it could ignite a spark that ignites the gasoline in the engine bay.

Once the cables are connected, start the vehicle that is disabled and allow it to run for around five minutes before disconnecting them in reverse order. Keep in mind that the battery on your Saab 9-3 is charged while you drive, so it will take a while to get the battery back to its original level. It is a good idea to purchase a spare key fob as soon as you can, since replacing the sole working one requires the installation of a new computer module and special programming to convince it that your lost keys aren't attempting to steal the car.

Replacement case

Many saab replacement key programming owners have only one key for their car and if they lose it, it's going to cost them. It's expensive to purchase the key and also requires replacing the CIM or TWICE for older models. It's best to have a backup key in the event of theft or other disaster and the most effective way is to buy an extra key as soon as you can. Even if the key is "new" it will not function.

The dealer will charge you the highest dollars if you only have one working key. We can reset and reprogram the computer's EEEPROM to be able to accept a new key without having to replace the entire system. This could help you save money. It's also much less expensive than waiting until you lose your only key.
