saab key fob repair Key Programming

saab car key cars made since 1994 have an immobilizer feature built on coded keys. Adding an extra key requires an entirely new transponder and programming. This is usually done at the dealer with a specialized Tech2 diagnostic tool.

This can be expensive. This is why you should always have a spare key on hand.

Transponder key

The transponder key is a piece of hardware equipped with an electronic chip. It sends a signal to car when it is placed in the ignition. The car will then check the signal to determine whether it matches that of the key. If the signals are in sync, the car will open and start. This is a great method to protect your vehicle from theft.

Transponder keys may be a popular addition to automobiles, but they are not as safe as traditional metal keys. The metal part of the traditional key can be easily cut and copied, whereas the transponder is protected by an electronic chip which protects it. The chip has a unique code programmed into the car's computers to identify it.

When a saab 93 key replacement key fob is used the car recognizes it and allows it to turn on. But, it's only able to do this if the key fob is equipped with a chip that is not modified that has been programmed to match. The car will not start in the event that the key has not been programmed to match.

It is crucial to have an extra saab 93 key replacement key. This is especially important especially if you live in a rural area with numerous car thieves. The good news is that it's possible to find a new key for your Saab without having to go to a dealership and pay the high costs that they charge. In the majority of instances, you can get a brand new key made right on the spot for less than half the price of what you would pay at the dealer.

Wired key

Saab cars typically come with two keys when they're new. If you only have one, it is best to acquire an extra key fob as soon as you can, because if you lose it, your car will require a new CIM unit and the locking cylinders need to be replaced. This could be expensive especially if you're buying a second-hand car.

The next step is to connect the wires of the column and row to the microcontroller. This is the most laborious part of the project and will require a lot of soldering. It's not a common way to go about it, however, you should determine how to connect and solder each column and row. For this keyboard, there are 5 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 the time to connect them to key switches. Solder a diode to each key switch pin. This will protect the pins from current, and prevent them from being cut off. A diode lets current only flow in only one direction. It has a visual indicator, a black band, that indicates the direction in which current will flow.

Some of the tools you can find at auto parts storeslike the Autel MaxiIM IM608 Pro and IM508 -- can assist customers at the shop or DIY customers in some cases program replacement keys and restore lost immobilizer data, Sanabria says. The tools plug into OBD ports and guide the customer through each step, making the process easier than replacing the car's computer.

Jumpstarting the battery

Most people keep a set in their trunk to jump-start their car in an emergency, but it may not be a good option for vehicles with newer technology. These cars have a variety of computers and digital devices that communicate with one another. A surge of voltage when the battery is connected another could cause damage to the components and render your vehicle unusable.

Connect the cables to the vehicle that is operating. Allow it to 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 of the black cable to a clean, unpainted metal surface underneath the disabled vehicle's hood. An engine block is an excellent choice. The black cable is not to be connected to the negative terminal of the dead battery. This could create sparks, which would ignite the gasoline inside the engine compartment.

Once the cables are connected, you can start the vehicle that has been disabled and let it run for approximately five minutes before you disconnect the cables in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It takes a while for it to recharge again. It's a good idea purchase a spare fob as soon as you can, since replacing the only working one requires the installation of a brand new computer module and a special program to convince it that your lost keys aren't attempting to steal the car.

Replacement case

Saab owners usually have only one car key, and if that is lost, they'll be charged. It's expensive to buy an additional key and it requires replacing the CIM or TWICE in the case of older models. It's best to have a spare key in the event of theft or other disaster, and the best way is to purchase a second key as early as you can. Even when the key is "new" it will not work.

The dealer will charge the highest dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM to make it ready to accept a replacement key without having to replace the entire system. That can save you lots of money. It's also cheaper than waiting until you lose the only key.
