saab fob key replacement Key Programming

saab 9-3 key cars manufactured since 1994 feature an immobilizer system based on keys that are coded. In order to add a second key, it requires an entirely new transponder and programming. This is usually done at the dealer using a Tech2 diagnostic tool.

The problem is that it can be very costly. This is why it is important to always have a spare key available.

Transponder key

The transponder can be described as a key that is equipped with an electronic chip. This chip sends a signal when the key is put into the ignition. The car then checks to see if the signal matches the one on the key. If the signals match the car will then unlock itself and start. This is a fantastic way to protect your vehicle from theft.

Transponder keys may be an increasingly popular feature for cars, but they are not as secure as traditional metal keys. The metal component of the traditional key is easily cut and copied, however transponders are protected by an electronic chip that protects it. The chip has an unique code that is programmed into the car's computer to identify it.

When a Saab key programmer key fob is used the car recognizes it and allows it to turn on. However, it can only do this if the fob has an unmodified chip that has been programmed to match the original. The car won't start if the key is not programmed to match.

It is crucial to have a spare Saab key. This is especially important for those who live in a rural location that has many car thieves. You can get a new key for your saab key programmer by visiting the dealership and not paying their pricey prices. You can have an original key made on the spot for less than half of what you would spend at an auto dealer.

Wired key

Saab cars are usually delivered with two keys. If you have only one, it's best to acquire an extra key fob as soon as you can as if you lose it, the car will require an entirely new CIM unit and the locking cylinders will need to be replaced. This can be costly, especially if you are buying a used car.

The next step is to connect the wires for columns and rows to your microcontroller. This is the most challenging part of the project and will require a good amount of soldering. It's not a standard way to go about it, but you should determine how to program saab 9-3 key fob to route and connect each column and row. There are 22 microcontroller pins and wires to connect to this keyboard. It has 5 rows and 17 columns.

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

Some of the tools available at auto parts stores -- such as the Autel MaxiIM IM608 Pro and IM508 -- may aid shop customers or DIY customers in certain instances programme replacement keys and recover the lost immobilizer's data, Sanabria says. The tools connect to OBD ports and help the customer through each step making the process simpler than replacing the vehicle's computer.

Jumpstarting the battery

Most people keep a set of jumper cables in their trunk to use in an emergency, but jumping a battery on newer cars might not be the most efficient option. These vehicles have many digital and computer systems that communicate with one another. A surge in voltage when a battery is connected to another could cause damage to the components, rendering your car undriveable.

Connect the cables to the vehicle working. Let it run for two minutes. Attach the red clip on the positive terminal of the good battery. (It will read "POS" or "+".) Attach the other end to a clean, unpainted metal surface under the hood of your disabled vehicle. The engine block is a good choice. Do not connect the black cable to the negative terminal on the dead battery, since this could trigger a spark that ignites the gasoline in the engine bay.

Once the cables are connected the vehicle that is disabled and allow it to run for around five minutes before disconnecting the cables in reverse order. The battery in your Saab 9-3 will be recharged as you drive. It will take some time for it to drop back down. It's a good idea to purchase a spare key fob as soon as you can, because replacing the only working one requires the installation of a new computer module and special programming to convince it that the lost keys aren't in the process of trying to steal the car.

replacement key for saab 93 case

Many Saab owners only have one key for their car and if they lose it, the cost will be. It's expensive to buy an additional key and it requires replacing the CIM or TWICE for older models. In the event of theft or any other catastrophe it is best to have a spare key. Even when the key is "new" it won't work.

The dealer will charge you the most expensive dollar if you only have one working key. We can reset and reprogram the computer's EEEPROM in order to be able to accept a new key without replacing the entire system. This could save you lots of money. It's more affordable instead of waiting until you lose the sole key.
